Advanced information gathering for targeted activities

[00002] This application claims the benefit of U.S. Provisional Application No. 60/110,818 filed Nov. 12, 1998.

[00003] The present invention relates to agent based systems and more particularly to an agent based system which automatically creates background information for an upcoming event.

[00004] Agent based technology has become increasingly important for use with applications designed to interact with a user for performing various computer based tasks in foreground and background modes. Agent software comprises computer programs that are set on behalf of users to perform routine, tedious and time-consuming tasks. To be useful to an individual user, an agent must be personalized to the individual user's goals, habits and preferences. Thus, there exists a substantial requirement for the agent to efficiently and effectively acquire user-specific knowledge from the user and utilize it to perform tasks on behalf of the user.

[00005] The concept of agency, or the user of agents, is well established. An agent is a person authorized by another person, typically referred to as a principal, to act on behalf of the principal. In this manner the principal empowers the agent to perform any of the tasks that the principal is unwilling or unable to perform. For example, an insurance agent may handle all of the insurance requirements for a principal, or a talent agent may act on behalf of a performer to arrange concert dates.

[00006] With the advent of the computer, a new domain for employing agents has arrived. Significant advances in the realm of expert systems enable computer programs to act on behalf of computer users to perform routine, tedious and other time-consuming tasks. These computer programs are referred to as “software agents.”

[00007] Moreover, there has been a recent proliferation of computer and communication networks. These networks permit a user to access vast amounts of information and services without, essentially, any geographical boundaries. Thus, a software agent has a rich environment to perform a large number of tasks on behalf of a user. For example, it is now possible for an agent to make an airline reservation, purchase the ticket, and have the ticket delivered directly to a user. Similarly, an agent could scan the Internet and obtain information ranging from the latest sports or news to a particular graduate thesis in applied physics. Current solutions fail to apply agent technology to existing calendar technology to provide targeted acquisition of background information for a user's upcoming events.

[00008] According to a broad aspect of a preferred embodiment of the invention, an agent based system assists in preparing an individual for an upcoming meeting by helping him/her retrieve relevant information about the meeting from various sources. The system obtains input text in character form indicative of the target meeting from the a calendar program that includes the time of the meeting. As the time of the meeting approaches, the calendar program is queried to obtain the text of the target event and that information is utilized as input to the agent system. Then, the agent system parses the input meeting text to extract its various components such as title, body, participants, location, time etc. The system also performs pattern matching to identify particular meeting fields in a meeting text. This information is utilized to query various sources of information on the web and obtain relevant stories about the current meeting to send back to the calendaring system. For example, if an individual has a meeting with Netscape and Microsoft to talk about their disputes, the system obtains this initial information from the calendaring system. It will then parse out the text to realize that the companies in the meeting are “Netscape” and “Microsoft” and the topic is “disputes”. It will then surf the web for relevant information concerning the topic. Thus, in accordance with an objective of the invention, the system updates the calendaring system and eventually the user with the best information it can gather to prepare for the target meeting. In accordance with a preferred embodiment, the information is stored in a file that is obtained via selection from a link imbedded in the calendar system.

[00036] A preferred embodiment of a system in accordance with the present invention is preferably practiced in the context of a personal computer such as an IBM compatible personal computer, Apple MACINTOSH computer or UNIX based workstation. A representative hardware environment is depicted in FIG. 1, which illustrates a typical hardware configuration of a workstation in accordance with a preferred embodiment having a central processing unit 110, such as a microprocessor, and a number of other units interconnected via a system bus 112. The workstation shown in FIG. 1 includes a Random Access Memory (RAM) 114, Read Only Memory (ROM) 116, an I/O adapter 118 for connecting peripheral devices such as disk storage units 120 to the bus 112, a user interface adapter 122 for connecting a keyboard 124, a mouse 126, a speaker 128, a microphone 132, and/or other user interface devices such as a touch screen (not shown) to the bus 112, communication adapter 134 for connecting the workstation to a communication network (e.g., a data processing network) and a display adapter 136 for connecting the bus 112 to a display device 138. The workstation typically has resident thereon an operating system such as the Microsoft Windows NT or Windows/95 Operating System (OS), the IBM OS/2 operating system, the MAC OS, or UNIX operating system. Those skilled in the art will appreciate that the present invention may also be implemented on platforms and operating systems other than those mentioned.

[00037] A preferred embodiment is written using JAVA, C, and the C++ language and utilizes object oriented programming methodology. Object oriented programming (OOP) has become increasingly used to develop complex applications. As OOP moves toward the mainstream of software design and development, various software solutions require adaptation to make use of the benefits of OOP. A need exists for these principles of OOP to be applied to a messaging interface of an electronic messaging system such that a set of

[00038] OOP classes and objects for the messaging interface can be provided. OOP is a process of developing computer software using objects, including the steps of analyzing the problem, designing the system, and constructing the program. An object is a software package that contains both data and a collection of related structures and procedures. Since it contains both data and a collection of structures and procedures, it can be visualized as a self-sufficient component that does not require other additional structures, procedures or data to perform its specific task. OOP, therefore, views a computer program as a collection of largely autonomous components, called objects, each of which is responsible for a specific task. This concept of packaging data, structures, and procedures together in one component or module is called encapsulation.

[00039] In general, OOP components are reusable software modules which present an interface that conforms to an object model and which are accessed at run-time through a component integration architecture. A component integration architecture is a set of architecture mechanisms which allow software modules in different process spaces to utilize each others capabilities or functions. This is generally done by assuming a common component object model on which to build the architecture.

[00040] It is worthwhile to differentiate between an object and a class of objects at this point. An object is a single instance of the class of objects, which is often just called a class. A class of objects can be viewed as a blueprint, from which many objects can be formed.

[00041] OOP allows the programmer to create an object that is a part of another object. For example, the object representing a piston engine is said to have a composition-relationship with the object representing a piston. In reality, a piston engine comprises a piston, valves and many other components; the fact that a piston is an element of a piston engine can be logically and semantically represented in OOP by two objects.

[00042] OOP also allows creation of an object that “depends from” another object. If there are two objects, one representing a piston engine and the other representing a piston engine wherein the piston is made of ceramic, then the relationship between the two objects is not that of composition. A ceramic piston engine does not make up a piston engine. Rather it is merely one kind of piston engine that has one more limitation than the piston engine; its piston is made of ceramic. In this case, the object representing the ceramic piston engine is called a derived object, and it inherits all of the aspects of the object representing the piston engine and adds further limitation or detail to it. The object representing the ceramic piston engine “depends from” the object representing the piston engine. The relationship between these objects is called inheritance.

[00043] When the object or class representing the ceramic piston engine inherits all of the aspects of the objects representing the piston engine, it inherits the thermal characteristics of a standard piston defined in the piston engine class. However, the ceramic piston engine object overrides these ceramic specific thermal characteristics, which are typically different from those associated with a metal piston. It skips over the original and uses new functions related to ceramic pistons. Different kinds of piston engines have different characteristics, but may have the same underlying functions associated with it (e.g., how many pistons in the engine, ignition sequences, lubrication, etc.). To access each of these functions in any piston engine object, a programmer would call the same functions with the same names, but each type of piston engine may have different/overriding implementations of functions behind the same name. This ability to hide different implementations of a function behind the same name is called polymorphism and it greatly simplifies communication among objects.

[00044] With the concepts of composition-relationship, encapsulation, inheritance and polymorphism, an object can represent just about anything in the real world. In fact, our logical perception of the reality is the only limit on determining the kinds of things that can become objects in object-oriented software. Some typical categories are as follows:

• [00045] Objects can represent physical objects, such as automobiles in a traffic-flow simulation, electrical components in a circuit-design program, countries in an economics model, or aircraft in an air-traffic-control system.
• [00046] Objects can represent elements of the computer-user environment such as windows, menus or graphics objects.
• [00047] An object can represent an inventory, such as a personnel file or a table of the latitudes and longitudes of cities.
• [00048] An object can represent user-defined data types such as time, angles, and complex numbers, or points on the plane.

[00049] With this enormous capability of an object to represent just about any logically separable matters, OOP allows the software developer to design and implement a computer program that is a model of some aspects of reality, whether that reality is a physical entity, a process, a system, or a composition of matter. Since the object can represent anything, the software developer can create an object which can be used as a component in a larger software project in the future.

[00050] If 90% of a new OOP software program consists of proven, existing components made from preexisting reusable objects, then only the remaining 10% of the new software project has to be written and tested from scratch. Since 90% already came from an inventory of extensively tested reusable objects, the potential domain from which an error could originate is 10% of the program. As a result, OOP enables software developers to build objects out of other, previously built, objects.

[00051] This process closely resembles complex machinery being built out of assemblies and sub-assemblies. OOP technology, therefore, makes software engineering more like hardware engineering in that software is built from existing components, which are available to the developer as objects. All this adds up to an improved quality of the software as well as an increased speed of its development.

[00052] Programming languages are beginning to fully support the OOP principles, such as encapsulation, inheritance, polymorphism, and composition-relationship. With the advent of the C++ language, many commercial software developers have embraced OOP. C++ is an OOP language that offers a fast, machine-executable code. Furthermore, C++ is suitable for both commercial-application and systems-programming projects. For now, C++ appears to be the most popular choice among many OOP programmers, but there is a host of other OOP languages, such as Smalltalk, common lisp object system (CLOS), and Eiffel. Additionally, OOP capabilities are being added to more traditional popular computer programming languages such as Pascal.

[00053] The benefits of object classes can be summarized, as follows:

• [00054] Objects and their corresponding classes break down complex programming problems into many smaller, simpler problems.
• [00055] Encapsulation enforces data abstraction through the organization of data into small, independent objects that can communicate with each other. Encapsulation protects the data in an object from accidental damage, but allows other objects to interact with that data by calling the object's member functions and structures.
• [00056] Subclassing and inheritance make it possible to extend and modify objects through deriving new kinds of objects from the standard classes available in the system. Thus, new capabilities are created without having to start from scratch.
• [00057] Polymorphism and multiple inheritance make it possible for different programmers to mix and match characteristics of many different classes and create specialized objects that can still work with related objects in predictable ways.
• [00058] Class hierarchies and containment hierarchies provide a flexible mechanism for modeling real-world objects and the relationships among them.
• [00059] Libraries of reusable classes are useful in many situations, but they also have some limitations. For example:
• [00060] Complexity. In a complex system, the class hierarchies for related classes can become extremely confusing, with many dozens or even hundreds of classes.
• [00061] Flow of control. A program written with the aid of class libraries is still responsible for the flow of control (i.e., it must control the interactions among all the objects created from a particular library). The programmer has to decide which functions to call at what times for which kinds of objects.
• [00062] Duplication of effort. Although class libraries allow programmers to use and reuse many small pieces of code, each programmer puts those pieces together in a different way. Two different programmers can use the same set of class libraries to write two programs that do exactly the same thing but whose internal structure (i.e., design) may be quite different, depending on hundreds of small decisions each programmer makes along the way. Inevitably, similar pieces of code end up doing similar things in slightly different ways and do not work as well together as they should.

[00063] Class libraries are very flexible. As programs grow more complex, more programmers are forced to reinvent basic solutions to basic problems over and over again. A relatively new extension of the class library concept is to have a framework of class libraries. This framework is more complex and consists of significant collections of collaborating classes that capture both the small scale patterns and major mechanisms that implement the common requirements and design in a specific application domain. They were first developed to free application programmers from the chores involved in displaying menus, windows, dialog boxes, and other standard user interface elements for personal computers.

[00064] Frameworks also represent a change in the way programmers think about the interaction between the code they write and code written by others. In the early days of procedural programming, the programmer called libraries provided by the operating system to perform certain tasks, but basically the program executed down the page from start to finish, and the programmer was solely responsible for the flow of control. This was appropriate for printing out paychecks, calculating a mathematical table, or solving other problems with a program that executed in just one way.

[00065] The development of graphical user interfaces began to turn this procedural programming arrangement inside out. These interfaces allow the user, rather than program logic, to drive the program and decide when certain actions should be performed. Today, most personal computer software accomplishes this by means of an event loop which monitors the mouse, keyboard, and other sources of external events and calls the appropriate parts of the programmer's code according to actions that the user performs. The programmer no longer determines the order in which events occur. Instead, a program is divided into separate pieces that are called at unpredictable times and in an unpredictable order. By relinquishing control in this way to users, the developer creates a program that is much easier to use. Nevertheless, individual pieces of the program written by the developer still call libraries provided by the operating system to accomplish certain tasks, and the programmer must still determine the flow of control within each piece after being called by the event loop. Application code still “sits on top of” the system.

[00066] Even event loop programs require programmers to write a lot of code that should not need to be written separately for every application. The concept of an application framework carries the event loop concept further. Instead of dealing with all the nuts and bolts of constructing basic menus, windows, and dialog boxes and then making these things all work together, programmers using application frameworks start with working application code and basic user interface elements in place. Subsequently, they build from there by replacing some of the generic capabilities of the framework with the specific capabilities of the intended application.

[00067] Application frameworks reduce the total amount of code that a programmer has to write from scratch. However, because the framework is really a generic application that displays windows, supports copy and paste, and so on, the programmer can also relinquish control to a greater degree than event loop programs permit. The framework code takes care of almost all event handling and flow of control, and the programmer's code is called only when the framework needs it (e.g., to create or manipulate a proprietary data structure).

[00068] A programmer writing a framework program not only relinquishes control to the user (as is also true for event loop programs), but also relinquishes the detailed flow of control within the program to the framework. This approach allows the creation of more complex systems that work together in interesting ways, as opposed to isolated programs, having custom code, being created over and over again for similar problems.

[00069] Thus, as is explained above, a framework basically is a collection of cooperating classes that make up a reusable design solution for a given problem domain. It typically includes objects that provide default behavior (e.g., for menus and windows), and programmers use it by inheriting some of that default behavior and overriding other behavior so that the framework calls application code at the appropriate times.

[00070] There are three main differences between frameworks and class libraries:

• [00071] Behavior versus protocol. Class libraries are essentially collections of behaviors that you can call when you want those individual behaviors in your program. A framework, on the other hand, provides not only behavior but also the protocol or set of rules that govern the ways in which behaviors can be combined, including rules for what a programmer is supposed to provide versus what the framework provides.
• [00072] Call versus override. With a class library, the code the programmer instantiates objects and calls their member functions. It's possible to instantiate and call objects in the same way with a framework (i.e., to treat the framework as a class library), but to take full advantage of a framework's reusable design, a programmer typically writes code that overrides and is called by the framework. The framework manages the flow of control among its objects. Writing a program involves dividing responsibilities among the various pieces of software that are called by the framework rather than specifying how the different pieces should work together.
• [00073] Implementation versus design. With class libraries, programmers reuse only implementations, whereas with frameworks, they reuse design. A framework embodies the way a family of related programs or pieces of software work. It represents a generic design solution that can be adapted to a variety of specific problems in a given domain. For example, a single framework can embody the way a user interface works, even though two different user interfaces created with the same framework might solve quite different interface problems.

[00074] Thus, through the development of frameworks for solutions to various problems and programming tasks, significant reductions in the design and development effort for software can be achieved. A preferred embodiment of the invention utilizes HyperText Markup Language (HTML) to implement documents on the Internet together with a general-purpose secure communication protocol for a transport medium between the client and the Newco. HTTP or other protocols could be readily substituted for HTML without undue experimentation. Information on these products is available in T. Berners-Lee, D. Connoly, “RFC 1866: Hypertext Markup Language-2.0” (Nov. 1995); and R. Fielding, H, Frystyk, T. Bemers-Lee, J. Gettys and J.C. Mogul, “HypertextTransfer Protocol—HTTP/1.1: HTTP Working Group Internet Draft” (May 2, 1996). HTML is a simple data format used to create hypertext documents that are portable from one platform to another. HTML documents are SGML documents with generic semantics that are appropriate for representing information from a wide range of domains. HTML has been in use by the World-Wide Web global information initiative since 1990. HTML is an application of ISO Standard 8879:1986 Information Processing Text and Office Systems; Standard Generalized Markup Language (SGML).

[00075] To date, Web development tools have been limited in their ability to create dynamic Web applications which span from client to server and interoperate with existing computing resources. Until recently, HTML has been the dominant technology used in development of Web-based solutions. However, HTML has proven to be inadequate in the following areas:

• [00076] Poor performance;
• [00077] Restricted user interface capabilities;
• [00078] Can only produce static Web pages;
• [00079] Lack of interoperability with existing applications and data; and
• [00080] Inability to scale.

[00081] Sun Microsystem's Java language solves many of the client-side problems by:

• [00082] Improving performance on the client side;
• [00083] Enabling the creation of dynamic, real-time Web applications; and
• [00084] Providing the ability to create a wide variety of user interface components.

[00085] With Java, developers can create robust User Interface (UI) components. Custom “widgets” (e.g. real-time stock tickers, animated icons, etc.) can be created, and client-side performance is improved. Unlike HTML, Java supports the notion of client-side validation, offloading appropriate processing onto the client for improved performance. Dynamic, real-time Web pages can be created. Using the above-mentioned custom UI components, dynamic Web pages can also be created.

[00086] Sun's Java language has emerged as an industry-recognized language for “programming the Internet.” Sun defines Java as: “a simple, object-oriented, distributed, interpreted, robust, secure, architecture-neutral, portable, high-performance, multithreaded, dynamic, buzzword-compliant, general-purpose programming language. Java supports programming for the Internet in the form of platform-independent Java applets.” Java applets are small, specialized applications that comply with Sun's Java Application Programming Interface (API) allowing developers to add “interactive content” to Web documents (e.g. simple animations, page adornnents, basic games, etc.). Applets execute within a Java-compatible browser (e.g. Netscape Navigator) by copying code from the server to client. From a language standpoint, Java's core feature set is based on C++. Sun's Java literature states that Java is basically “C++, with extensions from Objective C for more dynamic method resolution”.

[00087] Another technology that provides similar function to JAVA is provided by Microsoft and ActiveX Technologies, to give developers and Web designers wherewithal to build dynamic content for the Internet and personal computers. ActiveX includes tools for developing animation, 3-D virtual reality, video and other multimedia content. The tools use Internet standards, work on multiple platforms, and are being supported by over 100 companies. The group's building blocks are called ActiveX Controls, small, fast components that enable developers to embed parts of software in hypertext markup language (HTML) pages. ActiveX Controls work with a variety of programming languages including Microsoft Visual C++, Borland Delphi, Microsoft Visual Basic programming system and, in the future, Microsoft's developmenttool for Java, code named “Jakarta.” ActiveX Technologies also includes ActiveX Server Framework, allowing developers to create server applications. One of ordinary skill in the art readily recognizes that ActiveX could be substituted for JAVA without undue experimentationto practice the invention.

[00088] In accordance with a preferred embodiment, BackgroundFinder (BF) is implemented as an agent responsible for preparing an individual for an upcoming meeting by helping him/her retrieve relevant information about the meeting from various sources. BF receives input text in character form indicative of the target meeting. The input text is generated in accordance with a preferred embodiment by a calendar program that includes the time of the meeting. As the time of the meeting approaches, the calendar program is queried to obtain the text of the target event and that information is utilized as input to the agent. Then, the agent parses the input meeting text to extract its various components such as title, body, participants, location, time etc. The system also performs pattern matching to identify particular meeting fields in a meeting text. This information is utilized to query various sources of information on the web and obtain relevant stories about the current meeting to send back to the calendaring system. For example, if an individual has a meeting with Netscape and Microsoft to talk about their disputes, and would obtain this initial information from the calendaring system. It will then parse out the text to realize that the companies in the meeting are “Netscape” and “Microsoft” and the topic is “disputes.” Then, the system queries the web for relevant information concerning the topic. Thus, in accordance with an objective of the invention, the system updates the calendaring system and eventually the user with the best information it can gather to prepare the user for the target meeting. In accordance with a preferred embodiment, the information is stored in a file that is obtained via selection from a link imbedded in the calendar system.

[00089] A computer program in accordance with a preferred embodiment is organized in five distinct modules: BF.Main, BF.Parse, Background Finder.Error, BF.PatternMatching and BF.Search. There is also a formMain which provides a user interface used only for debugging purposes. The executable programs in accordance with a preferred embodiment never execute with the user interface and should only return to the calendaring system through Microsoft's Winsock control. A preferred embodiment of the system executes in two different modes which can be specified under the command line sent to it by the calendaring system. When the system runs in simple mode, it executes a keyword query to submit to external search engines. When executed in complex mode, the system performs pattern matching before it forms a query to be sent to a search engine.

[00090] The system in accordance with a preferred embodiment utilizes three user defined structures:

• [00091] 1. TMeetingRecord;
• [00092] 2. TPatternElement; and
• [00093] 3. TPatternRecord.

[00094] The user-defined structure, tMeetingRecord, is used to store all the pertinent information concerning a single meeting. This info includes userID, an original description of the meeting, the extracted list of keywords from the title and body of meeting etc. It is important to note that only one meeting record is created per instance of the system in accordance with a preferred embodiment. This is because each time the system is spawned to service an upcoming meeting, it is assigned a task to retrieve information for only one meeting. Therefore, the meeting record created corresponds to the current meeting examined. ParseMeetingText populates this meeting record and it is then passed around to provide information about the meeting to other functions.

[00095] If GoPatternMatch can bind any values to a particular meeting field, the corresponding entries in the meeting record is also updated. The structure of tMeetingRecord with each field described in parentheses is provided below in accordance with a preferred embodiment.

[00002]

A.1.1.1.1.1	Public Type tMeetingRecord
sUserID As String	(user id given by Munin)
sTitleOrig As String	(original non stop listed title we need to keep
	around to send back to Munin)
sTitleKW As String	(stoplisted title with only keywords)
sBodyKW As String	(stoplisted body with only keywords)
sCompany( ) As String	(companys identified in title or body through
	pattern matching)
sTopic( ) As String	(topics identified in title or body through
	pattern matching)
sPeople( ) As String	(people identified in title or body through
	pattern matching)
sWhen( ) As String	(time identified in title or body through pattern
	matching)
sWhere( ) As String	(location identified in title or body through
	pattern matching)
sLocation As String	(location as passed in by Munin)
sTime As String	(time as passed in by Munin)
sParticipants( ) As String	(all participants engaged as passed in by
	Munin)
sMeetingText As String	(the original meeting text w/o userid)
End Type

There are two other structures which are created to hold each individual pattern utilized in pattern matching. The record tAPatternRecord is an array containing all the components/elements of a pattern. The type tAPatternElement is an array of strings which represent an element in a pattern. Because there may be many “substitutes” for each element, we need an array of strings to keep track of what all the substitutes are. The structures of tAPatternElement and tAPatternRecord are presented below in accordance with a preferred embodiment.
Public Type tAPatternElement

• • [00098] elementArray( ) As String
    End Type
    Public Type tAPatternRecord
  • [00101] patternarray( ) As tAPatternElement
    End Type

[00103] Many constants are defined in each declaration section of the program which may need to be updated periodically as part of the process of maintaining the system in accordance with a preferred embodiment. The constants are accessible to allow dynamic configuration of the system to occur as updates for maintaining the code.

[00104] Included in the following tables are lists of constants from each module which I thought are most likely to be modified from time to time. However, there are also other constants used in the code not included in the following list. It does not mean that these non-included constants will never be changed. It means that they will change much less frequently.

[00109] The best way to depict the process flow and the coordination of functions between each other is with the five flowcharts illustrated in FIGS. 2 to 6. FIG. 2 depicts the overall process flow in accordance with a preferred embodiment. Processing commences at the top of the chart at function block 200 which launches when the program starts. Once the application is started, the command line is parsed to remove the appropriate meeting text to initiate the target of the background find operation in accordance with a preferred embodiment as shown in function block 210. A global stop list is generated after the target is determined as shown in function block 220. Then, all the patterns that are utilized for matching operations are generated as illustrated in function block 230. Then, by tracing through the chart, function block 200 invokes GoBF 240 which is responsible for logical processing associated with wrapping the correct search query information for the particular target search engine. For example, function block 240 flows to function block 250 and it then calls GoPatternMatch as shown in function block 260. To see the process flow of GoPatternMatch, we swap to the diagram titled “Process Flow for BF's Pattern Matching Unit.”

[00110] One key thing to notice is that functions depicted at the same level of the chart are called by in sequential order from left to right (or top to bottom) by their common parent function. For example, Main 200 calls ProcessCommandLine 210, then CreateStopListist 220, then CreatePatterns 230, then GoBackgroundFinder 240. FIGS. 3 to 6 detail the logic for the entire program, the parsing unit, the pattern matching unit and the search unit respectively. FIG. 6 details the logic determinative of data flow of key information through BackgroundFinder, and shows the functions that are responsible for creating or processing such information.

[00111] The Alta Vista search engine utilizes the identifies and returns general information about topics related to the current meeting as shown in function block 270 of FIG. 2. The system in accordance with a preferred embodiment takes all the keywords from the title portion of the original meeting text and constructs an advanced query to send to Alta Vista. The keywords are logically combined together in the query. The results are also ranked based on the same set of keywords. One of ordinary skill in the art will readily comprehend that a date restriction or publisher criteria could be facilitated on the articles we want to retrieve. A set of top ranking stories are returned to the calendaring system in accordance with a preferred embodiment.

[00112] The NewsPage search system is responsible for giving us the latest news topics related to a target meeting. The system takes all of the keywords from the title portion of the original meeting text and constructs a query to send to the NewsPage search engine. The keywords are logically combined together in the query. Only articles published recently are retrieved. The Newspage search system provides a date restriction criteria that is settable by a user according to the user's preference. The top ranking stories are returned to the calendaring system.

[00113] FIG. 3 is a user profile data model in accordance with a preferred embodiment. Processing commences at function block 300 which is responsible for invoking the program from the main module. Then, at function block 310, a wrapper function is invoked to prepare for the keyword extraction processing in function block 320. After the keywords are extracted, then processing flows to function block 330 to determine if the delimiters are properly positioned. Then, at function block 340, the number of words in a particular string is calculated and the delimiters for the particular field are and a particular field from the meeting text is retrieved at function block 350. Then, at function block 380, the delimiters of the string are again checked to assure they are placed appropriately. Finally, at function block 360, the extraction of each word from the title and body of the message is performed a word at a time utilizing the logic in function block 362 which finds the next closest word delimiter in the input phrase, function block 364 which strips unnecessary materials from a word and function block 366 which determines if a word is on the stop list and returns an error if the word is on the stop list.

[00114] The limitations associated with a simple searching method include the following:

• • [00115] 1. Because it relies on a stoplist of unwanted words in order to extract from the meeting text a set of keywords, it is limited by how comprehensive the stoplist is. Instead of trying to figure out what parts of the meeting text we should throw away, we should focus on what parts of the meeting text we want.
  • [00116] 2. A simple search method in accordance with a preferred embodiment only uses the keywords from a meeting title to form queries to send to Alta Vista and NewsPage. This ignores an alternative source of information for the query, the body of the meeting notice. We cannot include the keywords from the meeting body to form our queries because this often results in queries which are too long and so complex that we often obtain no meaningful results.
  • [00117] 3. There is no way for us to tell what each keyword represents. For example, we may extract “Andy” and “Grove” as two keywords. However, a simplistic search has no way knowing that “Andy Grove” is in fact a person's name. Imagine the possibilities if we could somehow intelligently guess that “Andy Grove” is a person's name. We can find out if he is an Andersen person and if so what kind of projects he's been on before etc. etc.
  • [00118] 4. In summary, by relying solely on a stoplist to parse out unnecessary words, we suffer from “information overload”.

[00119] Here's how the pattern matching system can address each of the corresponding issues above in accordance with a preferred embodiment.

• [00120] 1. By doing pattern matching, we match up only parts of the meeting text that we want and extract those parts.
• [00121] 2. By performing pattern matching on the meeting body and extracting only the parts from the meeting body that we want. Our meeting body will not go to complete waste then.
• [00122] 3. Pattern matching is based on a set of templates that we specify, allowing us to identify people names, company names etc from a meeting text.
• [00123] 4. In summary, with pattern matching, we no longer suffer from information overload. Of course, the big problem is how well our pattern matching works. If we rely exclusively on artificial intelligence processing, we do not have a 100% hit rate. We are able to identify about 20% of all company names presented to us.

[00124] A pattern in the context of a preferred embodiment is a template specifying the structure of a phrase we are looking for in a meeting text. The patterns supported by a preferred embodiment are selected because they are templates of phrases which have a high probability of appearing in someone's meeting text. For example, when entering a meeting in a calendar, many would write something such as “Meet with Bob Dutton from Stanford University next Tuesday.” A common pattern would then be something like the word “with” followed by a person's name (in this example it is Bob Dutton) followed by the word “from” and ending with an organization's name (in this case, it is Stanford University).

[00125] The common terminology associated with pattern matching is provided below.

• [00126] Pattern: a pattern is a template specifying the structure of a phrase we want to bind the meeting text to. It contains sub units.
• [00127] Element: a pattern can contain many sub-units. These subunits are called elements. For example, in the pattern “with $PEOPLE$ from $COMPANY$”, “with” “$PEOPLE$” “from” “$COMPANY$” are all elements.
• [00128] Placeholder: a placeholder is a special kind of element in which we want to bind a value to.Using the above example, “$PEOPLE$” is a placeholder.
• [00129] Indicator: an indicator is another kind of element which we want to find in a meeting text but no value needs to bind to it. There may be often more than one indicator we are looking for in a certain pattern. That is why an indicator is not an “atomic” type.
• [00130] Substitute: substitutes are a set of indicators which are all synonyms of each other. Finding any one of them in the input is good.

[00131] There are five fields which are identified for each meeting:

• • [00132] Company ($COMPANY$)
  • [00133] People ($PEOPLE$)
  • [00134] Location ($LOCATION$)
  • [00135] Time ($TIME$)
  • [00136] Topic ($TOPIC_UPPER$) or ($TOPIC_ALL$)

[00137] In parentheses are the placeholders I used in my code as representation of the corresponding meeting fields.

[heading-00138] Each placeholder has the following meaning:

[none]

• • [00139] $COMPANY$: binds a string of capitalized words (e.g. Meet with Joe Carter of <Andersen Consulting >)
  • [00140] $PEOPLE$: binds series of string of two capitalized words potentially connected by “,” “and” or “&” (e.g. Meet with <Joe Carter>of Andersen Consulting, Meet with <Joe Carter and Luke Hughes>of Andersen Consulting)
  • [00141] $LOCATION$: binds a string of capitalized words (e.g. Meet Susan at <Palo Alto Square>)
  • [00142] $TIME$: binds a string containing the format #:## (e.g. Dinner at <6:30 pm>)
  • [00143] $TOPIC_UPPER$: binds a string of capitalized words for our topic (e.g. <Stanford Engineering Recruiting>Meeting to talk about new hires).
  • [00144] $TOPIC_ALL$: binds a string of words without really caring if it's capitalized or not. (e.g. Meet to talk about <ubiquitous computing>)

[00145] Here is a table representing all the patterns supported by BF. Each pattern belongs to a pattern group. All patterns within a pattern group share a similar format and they only differ from each other in terms of what indicators are used as substitutes. Note that the patterns which are grayed out are also commented in the code. BF has the capability to support these patterns but we decided that matching these patterns is not essential at this point.

[00146] FIG. 4 is a detailed flowchart of pattern matching in accordance with a preferred embodiment. Processing commences at function block 400 where the main program invokes the pattern matching application and passes control to function block 410 to commence the pattern match processing. Then, at function block 420, the wrapper function loops through to process each pattern which includes determining if a part of the test string can be bound to a pattern as shown in function block 430. Then, at function block 440, various placeholders are bound to values if they exist, and in function block 441, a list of names separated by punctuation are bound, and at function block 442 a full name is processed by finding two capitalized words as a full name and grabbing the next letter after a space after a word to determine if it is capitalized. Then, at function block 443, time is parsed out of the string in an appropriate manner and the next word after a blank space in function block 444. Then, at function block 445, the continuous phrases of capitalized words such as company, topic or location are bound and in function block 446, the next word after the blank is obtained for further processing in accordance with a preferred embodiment. Following the match meeting field processing, function block 450 is utilized to loacte an indicator which is the head of a pattern, the next word after the blank is obtained as shown in function block 452 and the word is checked to determine if the word is an indicator as shown in function block 454. Then, at function block 460, the string is parsed to locate an indicator which is not at the end of the pattern and the next word after unnecessary white space such as that following a line feed or a carriage return is processed as shown in function block 462 and the word is analyzed to determine if it is an indicator as shown in function block 464. Then, in function block 470, the temporary record is reset to the null set to prepare it for processing the next string and at function block 480, the meeting record is updated and at function block 482 a check is performed to determine if an entry is already made to the meeting record before parsing the meeting record again.

[00147] Now that we have identified fields within the meeting text which we consider important, there are quite a few things we can do with it. One of the most important applications of pattern matching is of course to improve the query we construct which eventually gets submitted to Alta Vista and News Page. There are also a lot of other options and enhancements which exploit the results of pattern matching that we can add to BF. These other options will be described in the next section. The goal of this section is to give the reader a good sense of how the results obtained from pattern matching can be used to help us obtain better search results.

[00148] FIG. 5 is a flowchart of the detailed processing for preparing a query and obtaining information from the Internet in accordance with a preferred embodiment. Processing commences at function block 500 and immediately flows to function block 510 to process the wrapper functionality to prepare for an Internet search utilizing a web search engine. If the search is to utilize the Alta Vista search engine, then at function block 530, the system takes information from the meeting record and forms a query in function blocks 540 to 560 for submittal to the search engine. If the search is to utilize the NewsPage search engine, then at function block 520, the system takes information from the meeting record and forms a query in function blocks 521 to 528.

[00149] The strength of the Alta Vista search engine is that it provides enhanced flexibility. Using its advance query method, one can construct all sorts of Boolean queries and rank the search however you want. However, one of the biggest drawbacks with Alta Vista is that it is not very good at handling a large query and is likely to give back irrelevant results. If we can identify the topic and the company within a meeting text, we can form a pretty short but comprehensive query which will hopefully yield better results. We also want to focus on the topics found. It may not be of much merit to the user to find out info about a company especially if the user already knows the company well and has had numerous meetings with them. It's the topics they want to research on.

[00150] The strength of the News Page search engine is that it does a great job searching for the most recent news if you are able to give it a valid company name. Therefore when we submit a query to the news page web site, we send whatever company name we can identify and only if we cannot find one do we use the topics found to form a query. If neither one is found, then no search is performed. The algorithm utilized to form the query to submit to Alta Vista is illustrated in FIG. 7. The algorithmn that we will use to form the query to submit to News Page is illustrated in FIG. 8.

[00151] The following table describes in detail each function in accordance with a preferred embodiment. The order in which functions appear mimics the process flow as closely as possible. When there are situations in which a function is called several times, this function will be listed after the first function which calls it and its description is not duplicated after every subsequent function which calls it.

[00002]

Procedure
Name	Type	Called By	Description
Main	Public	None	This is the main
(BF.Main)	Sub		function where
			the program first
			launches. It
			initializes BF
			with the
			appropriate para-
			meters (e.g.
			Internet time-
			out, stoplist . . . )
			and calls GoBF
			to launch the
			main part of
			the program.
ProcessCom-	Private-	Main	This function
mandLine	Sub		parses the
(BF.Main)			command line. It
			assumes that the
			delimiter indicating
			the beginning of
			input from
			Munin is stored in
			the constant
			CMD—
			SEPARATOR.
CreateStopList	Private	Main	This function sets
(BF.Main)	Func-		up a stop
	tion		list for future
			use to parse out
			unwanted words
			from the meeting
			text. There
			are commas on each
			side of each word
			to enable straight
			checking.
CreatePatterns	Public	Main	This procedure is
(BF.Pattern	Sub		called once
Match)			when BF is first
			initialized to
			create all the
			potential patterns
			that portions of
			the meeting text
			can bind to. A
			pattern can
			contain however
			many elements as
			needed. There
			are two types
			of elements. The
			first type of
			elements are
			indicators. These
			are real words
			which delimit the
			potential of a
			meeting field
			(e.g. company)
			to follow. Most
			of these indicators
			are stop words
			as expected
			because stop
			words are words
			usually common
			to all
			meeting text so
			it makes sense
			they form patterns.
			The second type
			of elements are
			special strings
			which represent
			placeholders. A
			placeholder is
			always in the
			form of $*$
			where * can
			be either
			PEOPLE,
			COMPANY,
			TOPIC_UPPER,
			TIME, LOCATION
			or TOPIC_ALL.
			A pattern can
			begin with either
			one of the
			two types of
			elements and
			can be however
			long, involving
			however any
			number/type of
			elements. This
			procedure dynamically
			creates a new
			pattern record
			for each pattern
			in the table and
			it also dynamic-
			ally creates
			new tAPattern-
			Elements for
			each element
			within a pattern.
			In addition, there
			is the concept
			of being able to
			substitute indicators
			within a pattern.
			For example, the
			pattern
			$PEOPLE$ of
			$COMPANY$ is
			similar to the
			pattern
			$PEOPLE$ from
			$COMPANY$.
			“from” is a
			substitute for
			“of”. Our
			structure should
			be able to
			express such a
			need for
			substitution.
GoBF	Public	Main	This is a
(BF.Main)	Sub		wrapper
			procedurer
			that calls
			both the parsing
			and the searching
			subroutines of
			the BF. It
			is also responsible
			for sending data
			back to Munin.
ParseMeeting	Public	GoBackGround	This function
Text	Func-		takes the initial	Finder
(BF.Parse)	tion		meeting text
			and identifies
			the userID of
			the record as
			well as other
			parts of the
			meeting text
			including the
			title, body,
			participant list,
			location and time.
			In addition,
			we call a helper
			function Process-
			StopList to
			eliminate all
			the unwanted
			words from
			the original
			meeting title
			and meeting body
			so that only
			keywords are
			left. The
			information
			parsed out is
			stored in the
			MeetingRecord
			structure.
			Note that this
			function does
			no error checking
			and for the
			most time
			assumes that the
			meeting text
			string is
			correctly
			formatted by
			Munin.
			The important
			variable is
			this Meeting
			Record is the
			temp holder for
			all info
			regarding current
			meeting. It's
			eventually
			returned to
			caller.
FormatDelim-	Private	ParseMeetingText,	There are 4 ways
itation		DetermineNum	in which the
(BF.Parse)		Words,	delimiters can be
		GetAWord	placed. We
		From	take care of all
		String	these cases by
			reducing them
			down to Case 4
			in which there
			are no delimiters
			around but
			only between
			fields in a
			string (e.g.
			A::B::C)
DetermineNum	Public	ParseMeeting	This functions
Words	Func-	Text,	determines
(BF.Parse)	tion	ProcessStop	how many words
		List	there are in
			a string
			(stInEvalString)
			The function
			assumes that each
			word is separated
			by a designated
			separator as
			specified in
			stSeparator. The
			return type is
			an integer that
			indicates how
			many words have
			been found assuming
			each word
			in the string
			is separated by
			stSeparator.
			This function is
			always used along
			with GetAWord-
			FromString and
			should be called
			before calling
			GetAWordFrom
			String.
GetAWord	Public	ParseMeeting	This function
From String	Func-	Text,	extracts the ith
(BF.Parse)	tion	ProcessStop	word of the
		List	string
			(stInEvalString)
			assuming that each
			word in the
			string is separated
			by a designated
			separator contained
			in the variable
			stSeparator.
			In most cases,
			use this function
			with Determine-
			NumWords. The
			function returns
			the wanted word.
			This function checks
			to make sure that
			iInWordNum is
			within bounds
			so that i
			is not greater
			than the total
			number of words
			in string or
			less than/equal
			to zero. If it
			is out of bounds,
			we return empty
			string to indicate we
			can't get
			anything. We try
			to make sure
			this doesn't
			happen by calling
			DetermineNumWords
			first.
ParseAndClean	Private	ParseMeetingText	This function first
Phrase	Func-		grabs the word
(BF.Parse)	tion		and send it to
			CleanWord in
			order strip the
			stuff that nobody
			wants. There
			are things in
			parse Word that
			will kill the
			word, so we
			will need a
			method of
			looping through
			the body and
			rejecting words
			without killing the
			whole function
			i guess keep
			CleanWord and
			check a return
			value ok,
			now I have a
			word so I need
			to send it down
			the parse chain.
			This chain goes
			ParseClean-
			Phrase ->
			CleanWord ->
			EvaluateWord. If
			the word gets
			through the entire
			chain without
			killed, it will be
			added at the
			end to
			our keyword string.
			first would be
			the function
			that checks for
			“/” as a
			delimiter and
			extracts the
			parts of that.
			This I will call
			“StitchFace”
			(Denise is more
			normal and calls
			it GetAWord-
			FromString)
			if this finds
			words, then each
			of these will be
			sent, in turn,
			down the chain. If
			these get through
			the entire chain
			without being
			added or killed
			then they will be
			added rather
			than tossed.
FindMin	Private	ParseAndClean	This function
(BF.Parse)	Func-	Phrase	takes in 6
	tion		input values
			and evaluates to
			see what the
			minimum non
			zero value is.
			It first creates
			an array as a
			holder so that
			we can sort the
			five input
			values in
			ascending order.
			Thus the minimum
			value will be
			the first non
			zero value
			element of the
			array. If we
			go through
			entire array
			without finding
			a non zero value,
			we know that
			there is an
			error and we
			exit the function.
CleanWord	Private	ParseAnd	This function
(BF.Parse)	Func-	Clean	tries to clean
	tion	Phrase	up a word in
	Func-		a meeting text.
	tion		It first of all
			determines if the
			string is of a valid length.
			It then passes
			it through a
			series of tests to see it
			is clean and
			when needed, it
			will edit the word
			and strip unnecessary
			characters off of
			it. Such tests includes
			getting rid of file
			extensions, non
			chars, numbers etc.
EvaluateWord	Private	ParseAndClean	This function tests
(BF.Parse)	Func-	Phrase	to see if this
	tion		word is in the
			stop list so
			it can determine whether
			to eliminate the
			word from the
			original meeting text.
			If a word is
			not in the stoplist, it
			should stay around as
			a keyword and this
			function exits
			beautifully with no
			errors. However, if the
			words is a stopword, an
			error must be
			returned. We must
			properly delimit the
			input test string
			so we don't
			accidentally retrieve
			sub strings.
GoPattern	Public	GoBF	This procedure is
Match	Sub		called when our
(BF.Pattern			QueryMethod is set
Match)			to complex query
			meaning we do want to
			do all the pattern
			matching stuff.
			It's a simple wrapper
			function which
			initializes some arrays
			and then invokes
			pattern matching on
			the title and the
			body.
Match	Public	GoPattern	This procedure loops
Patterns	Sub	Match	through every pattern
(BF.Pattern			in the pattern
Match)			table and tries to
			identify different
			fields within a
			meeting text specified
			by sInEvalString.
			For debugging
			purposes it also
			tries to tabulate how
			many times a
			certain pattern was
			triggered and stores it
			in gTabulateMatches
			to see whichp
			pattern fired the
			most. gTabulateMatches
			is stored as a
			global because we
			want to be able to
			run a batch
			file of 40 or 50
			test strings
			and still be able
			to know how
			often a pattern was
			triggered.
MatchAPattern	Private	MatchPatterns	This function goes
(BF.Pattern	Func-		through each
Match)	tion		element in the
			current pattern.
			It first
			evaluates to
			determine
			whether element is
			a placeholder or
			an indicator.
			If it is a
			placeholder, then it
			will try to bind the
			placeholder with some
			value. If it
			is an indicator, then
			we try to
			locate it.
			There is a
			trick however.
			Depending on
			whether we are at
			current element is
			the head of the
			pattern or
			not we want to take
			different actions.
			If we are
			at the head, we want to
			look for the indicator or
			the placeholder. If we
			can't find it, then we
			know that the current
			pattern doesn't exist
			and we quit.
			However, if it is
			not the head, then we
			continue looking,
			because there may
			still be a head
			somewhere. We retry
			in this case.
etingField	Private	MatchAPattern	This function uses a
(BF.Pattern	Func-		big switch statement
Match)	tion		to first determine
			what kind of
			placeholder we are
			talking about
			and depending on what
			type of placeholder,
			we have specific
			requirements and
			different binding
			criteria as
			specified in the
			subsequent functions
			called such
			as BindNames,
			BindTime etc.
			If binding is
			successful we add
			it to our
			guessing record.
BindNames	Private	MatchMeetingField	In this function,
(BF.Pattern	Func-		we try to
Match)	tion		match names
			to the
			corresponding
			placeholder
			$PEOPLE$.
			Names
			are defined as
			any consecutive
			two words which are
			capitalized. We also
			what to retrieve
			a series of names
			which are connected
			by and, or &
			so we look until we
			don't see any
			of these 3
			separators anymore.
			Note that we
			don't want to bind
			single word names
			because it
			is probably
			too general anyway
			so we don't
			want to produce broad
			but irrelevant
			results. This
			function calls
			BindAFullName which
			binds
			one name so
			in a since
			BindNames collects
			all the results
			from BindAFullName
BindAFull	Private	BindNames	This function tries
Name	Func-		to bind a full
(BF.Pattern	tion		name. If the
Match)			$PEOPLE$

			because we've
			been deleting
			stuff off the head

			all along.
			If it is the
			head, we search
			until we find
			something that
			looks like a full
			name. If we
			can't find it,
			then there's no
			such pattern in the
			text entirely and
			we quit entirely
			from this pattern. This
			should eventually return
			us to the next
			pattern in
			MatchPatterns.

(BF.Pattern	tion		which is an
Match)			indicator. Note
			that this indicator
			SHOULD BE AT
			THE HEAD of the
			pattern otherwise
			it would have gone
			to the function
			LocateIndicator
			instead. Therefore,
			we keep on
			grabbing the next
			word until
			either there's no

			to grab (quit) or
			if we find
			one of the indicators
			we are looking for.
ContainIn	Private	LocatePattern	' This function

			LocatePatternHead
			instead.
			Because of this, if our
			pattern is to be
			satisfied, the
			next word we grab
			HAS to be the

			Thus we
			only grab one word,
			test to see if
			it is a valid indicator
			and then return result.

[00152] FIG. 6 is a flowchart of the actual code utilized to prepare and submit searches to the Alta Vista and Newspage search engines in accordance with a preferred embodiment.

[00153] Processing commences at function block 610 where a command line is utilized to update a calendar entry with specific calendar information. The message is next posted in accordance with function block 620 and a meeting record is created to store the current meeting information in accordance with function block 630. Then, in function block 640 the query is submitted to the Alta Vista search engine and in function block 650, the query is submitted to the Newspage search engine. When a message is returned from the search engine, it is stored in a results data structure as shown in function block 660 and the information is processed and stored in summary form in a file for use in preparation for the meeting as detailed in function block 670.

[00154] FIG. 7 provides more detail on creating the query in accordance with a preferred embodiment. Processing commences at function block 710 where the meeting record is parsed to obtain potential companies, people, topics, location and a time. Then, in function block 720, at least one topic is identified and in function block 720, at least one company name is identified and finally in function block 740, a decision is made on what material to transmit to the file for ultimate consumption by the user.

[00155] FIG. 8 is a variation on the query theme presented in FIG. 7. A meeting record is parsed in function block 800, a company is identified in function block 820, a topic is identified in function block 830 and finally in function block 840 the topic and or the company is utilized in formulating the query.

[00156] Alternative embodiments for adding various specific features for specific user requirements are discussed below.

[00157] To increase BF's performance, more patterns/pattern groups are added to the procedure “CreatePatterns.” The existing code for declaring patterns can be used as a template for future patterns. Because everything is stored as dynamic arrays, it is convenient to reuse code by cutting and pasting. The functions BindName, BindTime, BindCompanyLocTopic which are responsible for associating a value with a placeholder can be enhanced. The enhancement is realized by increasing the set of criteria for binding a certain meeting field in order to increase the number of binding values. For example, BindTime currently accepts and binds all values in the form of ##:## or #:##. To increase the times we can bind, we may want BindTime to also accept the numbers 1 to 12 followed by the more aesthetic time terminology “o'clock.” Vocabulary based recognition algorithms and assigning an accuracy rate to each guess BF makes allowing only guesses which meet a certain threshold to be valid.

[00158] Depending on what location the system identifies through pattern matching or alternatively depending on what location the user indicates as the meeting place, a system in accordance with a preferred embodiment suggests a plurality of fine restaurants whenever it detects the words lunch/dinner/breakfast. We can also use a site like company finder to confirm what we got is indeed a company name or if there is no company name that pattern matching can identify, we can use a company finder web site as a “dictionary” for us to determine whether certain capitalized words represent a company name. We can even display stock prices and breaking news for a company that we have identified.

[00159] FIG. 9 is a flow diagram that depicts the hardware and logical flow of control for a device and a software system designed to allow Web-based comparison shopping in conventional, physical, non-Web retail environments. A wireless phone or similar hand-held wireless device 920 with internet Protocol capability is combined with a miniature barcode reader 910 (installed either inside the phone or on a short cable) and used to scan the Universal Product Code (UPC) bar code on a book or other product 900. The wireless device 920 transmits the bar code via an antennae 930 to the Pocket BargainFinder Service Module (running on a Web server) 940, which converts it to (in the case of books) its International Standard Book Number or (in the case of other products) whatever identifier is appropriate. The Service Module then contacts the appropriate third-party Web site (s) to find price, shipping and availability information on the product from various Web suppliers 950. This information is formatted and displayed on the hand-held device's screen. The IP wireless phone or other hand held device 920 utilizes a wireless modem such as a RICOCHET SE Wireless Modem from Metricom. Utilizing this device, a user can hang out in a coffee shop with a portable computer perched on a rickety little table, with a latte sloshing dangerously close to the keyboard, and access the Internet at speeds rivaling direct connect via a telephone line.

[00160] The 8-ounce RICOCHET SE Wireless Modem is about as large as a pack of cigarettes and setup is extremely simple, simply attach the modem to the back of your portable's screen with the included piece of VELCRO fastener, plug the cable into the serial port, flip up the stubby antenna, and transmit. Software setup is equally easy: a straightforward installer adds the RICOCHET modem drivers and places the connection icon on your desktop. The functional aspects of the modem are identical to that of a traditional telephone modem.

[00161] Of course, wireless performance isn't nearly as reliable as a traditional dial-up phone connection. We were able to get strong connections in several San Francisco locations as long as we stayed near the windows. But inside CNET's all-brick headquarters, the RICOCHET modem couldn't connect at all. When you do get online, performance of up to 28.8 kbps is available with graceful degradation to slower speeds. But even the slower speeds didn't disappoint. Compared to the alternative—connecting via a cellular modem—the RICOCHET modem is much faster, more reliable, and less expensive to use. Naturally, the RICOCHET SE wireless modem is battery powered. The modem has continuous battery life of up to 12 hours. And in accordance with a preferred embodiment, we ran down our portable computer's dual cells before the RICOCHET modem_started to fade.

[00162] Thus, utilizing the wireless modem, a user may utilize the web server software 940 to identify the right product 950 and then use an appropriate device's key(s) to select a supplier and place an order in accordance with a preferred embodiment. The BargainFinder Service Module then consummates the order with the appropriate third-party Web supplier 960.

[00163] mySite! is a high-impact, Internet-based application in accordance with a preferred embodiment that is focused on the theme of delivering services and providing a personalized experience for each customer via a personal web site in a buyer-centric world. The services are intuitively organized around satisfying customer intentions—fundamental life needs or objectives that require extensive planning decisions, and coordination across several dimensions, such as financial planning, healthcare, personal and professional development, family life, and other concerns. Each member owns and maintains his own profile, enabling him to create and browse content in the system targeted specifically at him. From the time a demand for products or services is entered, to the completion of payment, intelligent agents are utilized to conduct research, execute transactions and provide advice. By using advanced profiling and filtering, the intelligent agents learn about the user, improving the services they deliver. Customer intentions include Managing Daily Logistics (e.g., email, calendar, contacts, to-do list, bill payment, shopping, and travel planning); and Moving to a New Community (e.g., finding a place to live, moving household possessions, getting travel and shipping insurance coverage, notifying business and personal contacts, learning about the new community). From a consumer standpoint, mySite! provides a central location where a user can access relevant products and services and accomplish daily tasks with ultimate ease and convenience.

[00164] From a business standpoint, mySite! represents a value-added and innovative way to effectively attract, service, and retain customers. Intention value networks allow a user to enter through a personalized site and, and with the assistance of a learning, intelligent agent, seamlessly interact with network participants. An intention value network in accordance with a preferred embodiment provides superior value. It provides twenty four hour a day, seven days a week access to customized information, advice and products. The information is personalized so that each member views content that is highly customized to assure relevance to the required target user.

[00165] An Egocentric Interface is a user interface crafted to satisfy a particular user's needs, preferences and current context. It utilizes the user's personal information that is stored in a central profile database to customize the interface. The user can set security permissions on and preferences for interface elements and content. The content integrated into the Egocentric Interface is customized with related information about the user. When displaying content, the Egocentric Interface will include the relationship between that content and the user in a way that demonstrates how the content relates to the user. For instance, when displaying information about an upcoming ski trip the user has signed up for, the interface will include information about events from the user's personal calendar and contact list, such as other people who will be in the area during the ski trip. This serves to put the new piece of information into a context familiar to the individual user.

[00166] FIG. 10A describes the Intention Value Network Architecture implementation for the World Wide Web. For simplification purposes, this diagram ignores the complexity pertaining to security, scalability and privacy. The customer can access the Intention Value Network with any Internet web browser 1010, such as Netscape Navigator or Microsoft Internet Explorer, running on a personal computer connected to the Internet or a Personal Digital Assistant with wireless capability. See FIG. 17 for a more detailed description of the multiple methods for accessing an Intention Value Network. The customer accesses the Intention Value Network through the unique name or IP address associated with the Integrator's Web Server 1020. The Integrator creates the Intention Value Network using a combination of resources, such as the Intention Database 1030, the Content Database 1040, the Supplier Profile Database 1050, and the Customer Profile Database 1060.

[00167] The Intention Database 1030 stores all of the information about the structure of the intention and the types of products and services needed to fulfill the intention. Information in this database includes intention steps, areas of interest, layout templates and personalization templates. The Content Database 1040 stores all of the information related to the intention, such as advice, referral information, personalized content, satisfaction ratings, product ratings and progress reports.

[00168] The Supplier Profile Database 1050 contains information about the product and service providers integrated into the intention. The information contained in this database provides a link between the intention framework and the suppliers. It includes product lists, features and descriptions, and addresses of the suppliers' product web sites. The Customer Profile Database 1060 contains personal information about the customers, such as name, address, social security number and credit card information, personal preferences, behavioral information, history, and web site layout preferences. The Supplier's Web Server 1070 provides access to all of the supplier's databases necessary to provide information and transactional support to the customer.

[00169] The Product Information Database 1080 stores all product-related information, such as features, availability and pricing. The Product Order Database 1090 stores all customer orders. The interface to this database may be through an Enterprise Resource Planning application offered by SAP, Baan, Oracle or others, or it may be accessible directly through the Supplier's Web Server or application server. The Customer Information Database 1091 stores all of the customer information that the supplier needs to complete a transaction or maintain customer records.

[00170] FIG. 10B is a flowchart providing the logic utilized to create a web page within the Egocentric Interface. The environment assumes a web server and a web browser connected through a TCP/IP network, such as over the public Internet or a private Intranet. Possible web servers could include Microsoft Internet Information Server, Netscape Enterprise Server or Apache. Possible web browsers include Microsoft Internet Explorer or Netscape Navigator. The client (i.e. web browser) makes a request 1001 to the server (i.e. web server) for a particular web page. This is usually accomplished by a user clicking on a button or a link within a web page. The web server gets the layout and content preferences 1002 for that particular user, with the request to the database keyed off of a unique user id stored in the client (i.e. web browser) and the User profile database 1003. The web server then retrieves the content 1004 for the page that has been requested from the content database 1005. The relevant user-centric content, such as calendar, email, contact list, and task list items are then retrieved 1006. (See FIG. 11 for a more detailed description of this process.) The query to the database utilizes the user content preferences stored as part of the user profile in the User profile database 1003 to filter the content that is returned. The content that is returned is then formatted into a web page 1007 according to the layout preferences defined in the user profile. The web page is then returned to the client and displayed to the user 1008.

[00171] FIG. 11 describes the process of retrieving user-centric content to add to a web page. This process describes 1006 in FIG. 10B in a more detailed fashion. It assumes that the server already has obtained the user profile and the existing content that is going to be integrated into this page. The server parses 1110 the filtered content, looking for instances of events, contact names and email addresses. If any of these are found, they are tagged and stored in a temporary holding space. Then, the server tries to find any user-centric content 1120 stored in various databases. This involves matching the tagged items in the temporary storage space with calendar items 1130 in the Calendar Database 1140; email items 1115 in the Email Database 1114; contact items 1117 in the Contact Database 1168; task list items 1119 in the Task List Database 1118; and news items 1121 in the News Database 1120. After retrieving any relevant user-centric content, it is compiled together and returned 1122.

[00172] The system allows the user to create a number of different personas that aggregate profile information into sets that are useful in different contexts. A user may create one persona when making purchases for his home. This persona may contain his home address and may indicate that this user is looking to find a good bargain when shopping. The same user may create a second persona that can be used when he is in a work context. This persona may store the user's work address and may indicate that the user prefers certain vendors or works for a certain company that has a discount program in place. When shopping for work-related items, the user may use this persona. A persona may also contain rules and restrictions. For instance, the work persona may restrict the user to making airline reservations with only one travel agent and utilizing booking rules set up by his employer.

[00173] FIG. 12 describes the relationship between a user, his multiple personas and his multiple profiles. At the User Level is the User Profile 1200. This profile describes the user and his account information. There is one unique record in the database for each user who has an account. Attached to each user are multiple Personas 1220, 1230 & 1240. These Personas are used to group multiple Profiles into useful contexts. For instance, consider a user who lives in San Francisco and works in Palo Alto, but has a mountain cabin in Lake Tahoe. He has three different contexts in which he might be accessing his site. One context is work-related. The other two are home-life related, but in different locations. The user can create a Persona for Work 1220, a Persona for Home 1230, and a Persona for his cabin home 1240. Each Persona references a different General Profile 1250, 1260 and 1270 which contains the address for that location. Hence, there are three General Profiles. Each Persona also references one of two Travel Profiles. The user maintains a Work Travel Profile 1280 that contains all of the business rules related to booking tickets and making reservations. This Profile may specify, for instance, that this person only travels in Business or First Class and his preferred airline is United Airlines. The Work Persona references this Work Travel Profile. The user may also maintain a Home Travel Profile 1290 that specifies that he prefers to travel in coach and wants to find non-refundable fairs, since they are generally cheaper. Both the Persona for Home and the Persona for the cabin home point to the Home Travel Profile.

[00174] FIG. 13 describes the data model that supports the Persona concept. The user table 1310 contains a record for each user who has an account in the system. This table contains a username and a password 1320 as well as a unique identifier. Each user can have multiple Personas 1330, which act as containers for more specialized structures called Profiles 1340. Profiles contain the detailed personal information in Profile Field 1350 records. Attached to each Profile are sets of Profile Restriction 1360 records. These each contain a Name 1370 and a Rule 1380, which define the restriction. The Rule is in the form of a pattern like (if x then y), which allows the Rule to be restricted to certain uses. An example Profile Restriction would be the rule that dictates that the user cannot book a flight on a certain airline contained in the list. This Profile Restriction could be contained in the “Travel” Profile of the “Work” Persona set up by the user's employer, for instance. Each Profile Field also contains a set of Permissions 1390 that are contained in that record. These permissions dictate who has what access rights to that particular Profile Field's information.

[00175] Satisfying Customer Intentions, such as Planning for Retirement or Relocating requires a specialized interface. Customer Intentions require extensive planning and coordination across many areas, ranging from financial security, housing and transportation to healthcare, personal and professional development, and entertainment, among others. Satisfying Intentions requires a network of complementary businesses, working across industries, to help meet consumers' needs.

[00176] An Intention-Centric Interface is a user interface designed to help the user manage personal Intentions. At any given point, the interface content is customized to show only content that relates to that particular Intention. The Intention-Centric Interface allows the user to manage the process of satisfying that particular Intention. This involves a series of discrete steps and a set of content areas the user can access. At any point, the user can also switch the interface to manage a different Intention, and this act will change the content of the interface to include only that content which is relevant to the satisfaction of the newly selected Intention.

[00177] FIG. 14 provides a detailed description of the data model needed to support an Intention-Centric Interface. Each User Persona 1410 (see FIG. 13 for a more detailed description of the Persona data model.) has any number of active User Intentions 1420. Each active User Intention is given a Nickname 1430, which is the display name the user sees on the screen. Each active User Intention also contains a number of Data Fields 1440, which contain any user data collected throughout the interaction with the user. For instance, if the user had filled out a form on the screen and one of the fields was Social Security Number, the corresponding Data Field would contain Name =“SSN” 1450, Value=“999-99-9999” 1460. Each User Intention also keeps track of Intention Step 1470 completion status. The Completion 1480 field indicates whether the user has completed the step. Every User Intention is a user-specific version of a Generic Intention 1490, which is the default model for that Intention for all users. The Generic Intention is customized through Custom Rules 1411 and 1412 that are attached to the sub-steps in the Intention. These Custom Rules are patterns describing how the system will customize the Intention for each individual user using the individual user's profile information.

[00178] An agent keeps track of key statistics for each user. These statistics are used in a manner similar to the Tamagochi virtual reality pet toy to encourage certain behaviors from the user. The statistics that are recorded are frequency of login, frequency of rating of content such as news articles, and activity of agents, measured by the number of tasks which it performs in a certain period. This information is used by the system to emotionally appeal to the user to encourage certain behaviors.

[00179] FIG. 15 describes the process for generating the page that displays the agent's current statistics. When the user requests the agent statistics page 1510 with the client browser, the server retrieves the users' statistics 1520 from the users' profile database 1530. The server then performs the mathematical calculations necessary to create a normalized set of statistics 1540. The server then retrieves the formulas 1550 from the content database 1560 that will be used to calculate the user-centric statistics. Graphs are then generated 1570 using the generic formulas and that user's statistics. These graphs are inserted into a template to create the statistics page 1580. This page is then returned to the user 1590.

[00180] The system provide Consumer Report-like service that is customized for each user based on a user profile. The system records and provides ratings from users about product quality and desirability on a number of dimensions. The difference between this system and traditional product quality measurement services is that the ratings that come back to the users are personalized. This service works by finding the people who have the closest match to the user's profile and have previously rated the product being asked for. Using this algorithm will help to ensure that the product reports sent back to the user only contain statistics from people who are similar to that user.

[00181] FIG. 16 describes the algorithm for determining the personalized product ratings for a user. When the user requests a product report 1610 for product X, the algorithm retrieves the profiles 1620 from the profile database 1630 (which includes product ratings) of those users who have previously rated that product. Then the system retrieves the default thresholds 1640 for the profile matching algorithm from the content database 1650. It then maps all of the short list of users along several dimensions specified in the profile matching algorithm 1660. The top n (specified previously as a threshold variable) nearest neighbors are then determined and a test is performed to decide if they are within distance y (also specified previously as a threshold variable) of the user's profile in the set 1670 using the results from the profile matching algorithm. If they are not within the threshold, then the threshold variables are relaxed 1680, and the test is run again. This processing is repeated until the test returns true. The product ratings from the smaller set of n nearest neighbors are then used to determine a number of product statistics 1690 along several dimensions. Those statistics are inserted into a product report template 1695 and returned to the user 1697 as a product report.

[00182] This system provides one central storage place for a person's profile. This storage place is a server available through the public Internet, accessible by any device that is connected to the Internet and has appropriate access. Because of the ubiquitous accessibility of the profile, numerous access devices can be used to customize services for the user based on his profile. For example, a merchant's web site can use this profile to provide personalized content to the user. A Personal Digital Assistant (PDA) with Internet access can synchronize the person's calendar, email, contact list, task list and notes on the PDA with the version stored in the Internet site. This enables the person to only have to maintain one version of this data in order to have it available whenever it is needed and in whatever formats it is needed.

[00183] FIG. 17 presents the detailed logic associated with the many different methods for accessing this centrally stored profile. The profile database 1710 is the central storage place for the users' profile information. The profile gateway server 1720 receives all requests for profile information, whether from the user himself or merchants trying to provide a service to the user. The profile gateway server is responsible for ensuring that information is only given out when the profile owner specifically grants permission. Any device that can access the public Internet 1730 over TCP/IP (a standard network communications protocol) is able to request information from the profile database via intelligent HTTP requests. Consumers will be able to gain access to services from devices such as their televisions 1740, mobile phones, Smart Cards, gas meters, water meters, kitchen appliances, security systems, desktop computers, laptops, pocket organizers, PDAs, and their vehicles, among others. Likewise, merchants 1750 will be able to access those profiles (given permission from the consumer who owns each profile), and will be able to offer customized, personalized services to consumers because of this.

[00184] One possible use of the ubiquitous profile is for a hotel chain. A consumer can carry a Smart Card that holds a digital certificate uniquely identifying him. This Smart Card's digital certificate has been issued by the system and it recorded his profile information into the profile database. The consumer brings this card into a hotel chain and checks in. The hotel employee swipes the Smart Card and the consumer enters his Pin number, unlocking the digital certificate. The certificate is sent to the profile gateway server (using a secure transmission protocol) and is authenticated. The hotel is then given access to a certain part of the consumer's profile that he has previously specified. The hotel can then retrieve all of the consumer's billing information as well as preferences for hotel room, etc. The hotel can also access the consumer's movie and dining preferences and offer customized menus for both of them. The hotel can offer to send an email to the consumer's spouse letting him/her know the person checked into the hotel and is safe. All transaction information can be uploaded to the consumer's profile after the hotel checks him in. This will allow partners of the hotel to utilize the information about the consumer that the hotel has gathered (again, given the consumer's permission).

[00185] In an Intention Value Network, the overall integrator system coordinates the delivery of products and services for a user. The integrator manages a network of approved suppliers providing products and services, both physical and virtual, to a user based on the user's preferences as reflected in the user's profile. The integrator manages the relationship between suppliers and consumers and coordinates the suppliers' fulfillment of consumers' intentions. It does this by providing the consumer with information about products and suppliers and offering objective advice, among other things.

[00186] FIG. 18 discloses the detailed interaction between a consumer and the integrator involving one supplier. The user accesses a Web Browser 1810 and requests product and pricing information from the integrator. The request is sent from the user's browser to the integrator's Web/Application Server 1820. The user's preferences and personal information is obtained from an integrator's customer profile database 1830 and returned to the Web/Application server. The requested product information is extracted from the supplier's product database 1840 and customized for the particular customer. The Web/Application server updates the supplier's customer information database 1850 with the inquiry information about the customer. The product and pricing information is then formatted into a Web Page 1860 and returned to the customer's Web Browser.

[00187] A suite of software agents running on the application and web servers are programmed to take care of repetitive or mundane tasks for the user. The agents work according to rules set up by the user and are only allowed to perform tasks explicitly defined by the user. The agents can take care of paying bills for the user, filtering content and emails, and providing a summary view of tasks and agent activity. The user interface for the agent can be modified to suit the particular user.

[00188] FIG. 19 discloses the logic in accordance with a preferred embodiment processing by an agent to generate a verbal summary for the user. When the user requests the summary page 1900, the server gets the user's agent preferences 1920, such as agent type, rules and summary level from the user profile database 1930. The server gets the content 1940, such as emails, to do list items, news, and bills, from the content database 1950. The agent parses all of this content, using the rules stored in the profile database, and summarizes the content 1960. The content is formatted into a web page 1970 according to a template. The text for the agent's speech is generated 1980, using the content from the content database 1990 and speech templates stored in the database. This speech text is inserted into the web page 1995 and the page is returned to the user 1997.

[00189] The above scenario requires the web site to maintain a guarantee of privacy of information according to a published policy. This system is the consumer's Trusted Third Party, acting on his behalf in every case, erring on the side of privacy of information, rather than on the side of stimulation of commerce opportunities. The Trusted Third Party has a set of processes in place that guarantee certain complicity with the stated policy.

[00190] This word extends the word “eCommerce” to mean “personalized electronic commerce.” FIG. 20 illustrates a display login in accordance with a preferred embodiment. The display is implemented as a Microsoft Internet Explorer application with an agent 2000 that guides a user through the process of interacting with the system to customize and personalize various system components to gather information and interact with the user's personal requirements. A user enters a username at 2010 and a password at 2020 and selects a button 2040 to initiate the login procedure. As the logo 2030 suggests, the system transforms electronic commerce into a personalized, so called “me” commerce.

[00191] FIG. 21 illustrates a managing daily logistics display in accordance with a preferred embodiment. A user is greeted by an animated agent 2100 with a personalized message 2190. The user can select from various activities based on requirements, including travel 2110, household chores 2120, finances 2130 and marketplace activities 2140. Icons 2142 for routine tasks such as e-mail, calendaring and document preparation are also provided to facilitate rapid navigation from one activity to another. Direct links 2146 are also provided to allow transfer of news and other items of interest. Various profiles can be selected based on where the user is located. For example, work, home or vacation. The profiles can be added 2170 as a user requires a new profile for another location. Various items 2180 of personal information are collected from the user to support various endeavors. Moreover, permissions 2150 are set for items 2180 to assure information is timely and current.

[00192] FIG. 22 illustrates a user main display in accordance with a preferred embodiment. World 2200 and local news 2210 is provided based on a user's preference. The user has also selected real estate 2230 as an item to provide direct information on the main display. Also, a different agent 2220 is provided based on the user's preference.

[00193] FIG. 23 illustrates an agent interaction in accordance with a preferred embodiment. The agent 2310 is communicating information 2300 to a user indicating that the user's life insurance needs have changed and pointing the user to the chart that best summarizes the information for the user. Particular tips 2395 are provided to facilitate more detailed information based on current user statistics. A chart 2370 of the user's life insurance needs is also highlighted at the center of the display to assist the user in determining appropriate action. A button 2380 is provided to facilitate changing the policy and a set of buttons 2390 are provided to assist a user in selecting various views of the user's insurance requirements.

[00194] An Event Backgrounder is a short description of an upcoming event that is sent to the user just before an event. The Event Backgrounder is constantly updated with the latest information related to this event. Pertinent information such as itinerary and logistics are included, and other useful information, such as people the user knows who might be in the same location, are also included. The purpose of the Event Backgrounder is to provide the most up-to-date information about an event, drawing from a number of resources, such as public web sites and the user's calendar and contact lists, to allow the user to react optimally in a given situation.

[00195] This software looks for opportunities to tell the user when a friend, family member or acquaintance is or is going to be in the same vicinity as the user. This software scans the user's calendar for upcoming events. It then uses a geographic map to compare those calendar events with the calendar events of people who are listed in his contact list. It then informs the user of any matches, thus telling the user that someone is scheduled to be near him at a particular time.

[00196] The term information overload is now relatively understood in both its definition as well as its implications and consequences. People have a finite amount of attention that is available at any one time, but there is more and more vying for that attention every day. In short, too much information and too little time are the primary factors complicating the lives of most knowledge workers today.

[00197] The first attempts to dynamically deal with information overload were primarily focused on the intelligent filtering of information such that the quantity of information would be lessened. Rather than simply removing random bits of information, however, most of these approaches tried to be intelligent about what information was ultimately presented to the user. This was accomplished by evaluating each document based on the user's interests and discarding the less relevant ones. It follows, therefore, that the quality was also increased.

[00198] Filtering the information is only a first step in dealing with information is this new age. Arguably, just as important as the quality of the document is having ready access to it. Once you have entered a meeting, a document containing critical information about the meeting subject delivered to your office is of little value. As the speed of business continues to increase fueled by the technologies of interconnectedness, the ability to receive quality information wherever and whenever you are becomes critical. This new approach is called intelligent information delivery and is heralding in a new information age.

[00199] A preferred embodiment demonstrates the intelligent information delivery theory described above in an attempt to not only reduce information overload, but to deliver high quality information where and when users' require it. In other words, the system delivers right information to the right person at the right time and the right place.

[heading-00202] Back-end Server (2400) Processes

[00203] FIG. 25 is a block diagram of a back end server in accordance with a preferred embodiment. The back-end (2400 of FIG. 24) is a computer system that has the following software active: Intelligent Agents Coordinator (Munin) 2580, Information Prioritization Subsystem 2530, a set of continuously and periodically running information gathering and processing Intelligent Agents 2500, 2502 and 2504, User Profiles Database 2542 and supporting software, Information Channels Database 2542 and supporting software, communications software 2550, information transformation software 2560, and auxiliary software.

[heading-00204] The Awareness Machine (2446 & 2448 of FIG. 24)

[00205] The Awareness Machine is a combination of hardware device and software application. The hardware consists of handheld personal computer and wireless communications device. The Awareness Machine reflects a constantly updated state-of-the-owner's-world by continually receiving a wireless trickle of information. This information, mined and processed by a suite of intelligent agents, consists of mail messages, news that meets each user's preferences, schedule updates, background information on upcoming meetings and events, as well as weather and traffic. The Awareness Machine is covered by another patent application.

[00206] FIG. 26 is a block diagram of a magic wall in accordance with a preferred embodiment.

[heading-00207] The Magic Wall

[heading-00208] The Magic Wall hardware includes:

[none]

• [00209] Computer system 2640 connected to the back-end server
• [00210] Sensor array 2634, 2630 and 2632 detects presence, position, and identity of a person
• [00211] Large touch-sensitive display 2620
• [00212] Sound input 2610 /output 2614 hardware
  The Magic Wall software supports:
• [00214] Multimedia output compatible with current Web standards
• [00215] Speech recognition
• [00216] Tactile input
• [00217] Intelligent agents representations in the form of speech-enabled animated characters
  The Magic Wall operates as follows:
• [00219] 1. If a user appears in the vicinity of Magic Wall, the sensor array triggers “user here” event that sends an environmental cue containing the person's id and the location to the Intelligent Agent Coordinator.
• [00220] 2. User is identified based on the information returned by the sensor array.
• [00221] 3. The Magic Wall switches to “locked on the user” mode. If another user approaches, the system will notify him or her that it cannot serve another user while the current user is being served.
• [00222] 4. Intelligent Agent Coordinator is notified about the user presence.
• [00223] 5. The Intelligent Agent Coordinator decides if there is pertinent to that user and Magic Wall location time-sensitive information to show (e.g. traffic report, meeting reminder). If such information exists, it is prepared for delivery. If not, control is transferred to the Information Prioritization Subsystem.
• [00224] 6. Information Prioritization Subsystem decides what information is most relevant to the user based on their personal profile, freshness of the information, and the Intelligent Agent Coordinator's prior suggestions.
• [00225] 7. The page of information identified as the most relevant to the user at this time and place is shown. The act of the information delivery can also include animation and speech output of the intelligent agent representation.
• [00226] 8. If user desires so, he or she can ask Magic Wall to show a particular page. The Magic Wall recognizes the speech fragment and then identifies and shows the requested page.
• [00227] 9. As the user departs from the Magic Wall area, the sensor array triggers “user left” event.
• [00228] 10.The Magic Wall switches back to the waiting state.
  Other Clients

[00230] The Web client is a standard browser navigating to a set of Web pages which allow user to see the same information that is available via the Magic Wall.

[00231] The e-mail client is any standard e-mail program.

[heading-00232] Intelligent Agent Coordinator Description

[00233] This piece of code is the coordinating agent (or meta-agent) for the Active Knowledge Management system. This means that all communications between the system and each user, as well as communication between the different minion agents are handled (coordinated) by the Intelligent Agent Coordinator. Examples of these minion agents are:

• [00234] BackgroundFinder—an agent that parses meeting text determining important keywords and phrases and finds background information on the meeting for each user
• [00235] TrafficFinder—an agent that finds traffic information for each user based on where they live
• [00236] Several other agents that are responsible for doing statistical analysis of the data in each user's profile and updating fields pertinent to that data

[00237] The Intelligent Agent Coordinator 2580 of FIG. 25 is also the user's “interface” to the system, in that whenever the user interacts with the system, regardless of the GUI or other end-user interface, they are ultimately dealing with (asking questions of or sending commands to) the Intelligent Agent Coordinator. The Intelligent Agent Coordinator has four primary responsibilities: 1) monitoring user activities, 2) handling information requests, 3) maintaining each user's profile, and 4) routing information to and from users and to and from the other respective agents.

[heading-00238] Monitoring User Activities

[00239] Anytime a user triggers a sensor the Intelligent Agent Coordinator receives an “environmental cue.” These cues not only enable the Intelligent Agent Coordinator to gain an understanding where users' are for information delivery purposes, but also to learn the standard patterns (arrival time, departure time, etc.) of each persons' life. These patterns are constantly being updated and refined in an attempt to increase the system's intelligence when delivering information. For instance, today it is not uncommon for a person to have several email accounts (work-based, home-based, mobile-based, etc.) as well as several different computers involved in the retrieval process for all of these accounts. Thus, for the Intelligent Agent Coordinator to be successful in delivering information to the correct location it must take into account all of these accounts and the times that the user is likely to be accessing them in order to maximize the probability that the user will see the information. This will be discussed further in another section.

[heading-00240] Handling Information Requests

[00241] The Intelligent Agent Coordinator handles information requests from other agents in order to personalize information intended for each user and to more accurately reflect each user's interests in the information they are given. These requests will commonly be related to the user's profile. For instance, if an agent was preparing a traffic report for a user it may request the traffic region (search string) of that user from the Intelligent Agent Coordinator. All access to the user's profile data is accessed in this method.

[heading-00242] Maintaining User Profiles

[00243] User profiles contain extensive information about the users. This information is a blend of user-specified data and information that the Intelligent Agent Coordinator has learned and extrapolated from each user's information and activities. In order to protect the data contained in the profiles, the Intelligent Agent Coordinator must handle all user information requests. The Intelligent Agent Coordinator is constantly modifying and updating these profiles by watching the user's activities and attempting to learn the patterns of their lives in order to assist in the more routine, mundane tasks. The Intelligent Agent Coordinator also employs other agents to glean meaning from each user's daily activities. These agents mine this data trying to discover indications of current interests, long-term interests, as well as time delivery preferences for each type of information. Another important aspect of the Intelligent Agent Coordinator's observations is that it also tries to determine where each user is physically located throughout the day for routing purposes.

[heading-00244] Information Routing

[00245] Most people are mobile throughout their day. The Intelligent Agent Coordinator tries to be sensitive to this fact by attempting to determine, both by observation (unsupervised learning) and from cues from the environment, where users are or are likely to be located. This is certainly important for determining where to send the user's information, but also for determining in which format to send the information. For instance, if a user were at her desk and using the web client, the Intelligent Agent Coordinator would be receiving indications of activity from her PC and would know to send any necessary information there. In addition, because desktop PCs are generally quite powerful, a full-featured, graphically intense version could be sent. However, consider an alternative situation: the Intelligent Agent Coordinator has received an indication (via the keycard reader next to the exit) that you have just left the building. Minutes later the Intelligent Agent Coordinator also receives notification that you have received an urgent message. The Intelligent Agent Coordinator, knowing that you have left the building and having not received any other indications, assumes that you are reachable via your handheld device (for which it also knows the capabilities) and sends the text of the urgent message there, rather than a more graphically-oriented version.

[heading-00246] Inherent Innovations

[00247] The Active Knowledge Management system represents some of the most advanced thinking in the world of knowledge management and human computer interaction. Some of the primary innovations include the following:

• [00248] The Intelligent Agent Coordinator as illustrated above.
• [00249] The development, demonstration, and realization of the theory of Intelligent Information Delivery
• [00250] Support for several channels of information delivery, all of which utilize a common back-end. For instance, if a user is in front of a Magic Wall the information will be presented in a multimedia-rich form. If the system determines that the user is mobile, the information will be sent by to their Awareness Machine in standard text. It facilitates delivery of information whenever and wherever a user requires the information.
• [00251] Personalization of information based not only on a static user profile, but also by taking into account history of the user interactions and current real-time situation including “who, where, and when” awareness.
• [00252] Utilization of fast and scalable Information Prioritization Subsystem that takes into account Intelligent Agents Coordinator opinion, user preferences, and history of user interactions. It takes the load of mundane decisions off the Intelligent Agents part therefore allowing the agents to be much more sophisticated and precise without compromising the system scalability.
• [00253] Speech recognition and speech synthesis in combination with intelligent agent animated representation and tactile input provides for efficient, intuitive, and emotionally rewarding interaction with the system.

[00254] The following code is written and executed in the Microsoft Active Server Pages environment in accordance with a preferred embodiment. It consists primarily of Microsoft Jscript with some database calls embedded in the code to query and store information in the database.
