Abstract

In a preferred embodiment, the invention dynamically generates content and presentation to a user by modifying conventional content, e.g. rendering, restructuring, filtering, or supplementing such content, based on information, e.g. annotations, stored in a database. The invention, referred to as the Meta-Web, allows a user at a Web browser, which may be any standard Web browser supported by a standard computing platform, to posit a query which is routed to a Meta-Web server. The Meta-Web server returns search results to the Web browser and the user may then explore the results, for example by clicking on a URL in the search results. The results returned to the user are produced after the Meta-Web server forwards the query to a search engine. The search engine then returns the results to the Meta-Web server. Unique to the invention is the provision of a registry14 which also receives search results and/or other information from the Meta-Web server, and that accumulates knowledge, meta-knowledge that was created at a time of entry of such knowledge, and meta-knowledge in the form of one or more annotations that accumulate over time, where the annotations include any of, but are not limited to, usefulness of said knowledge, additional user opinions, certifications of veracity of said knowledge, commentary by users, and connections between the knowledge and other units of knowledge. The Meta-Web server either combines both the search results and information from the registry, or operates upon the search results in accordance with information contained in the registry. The search results are augmented or modified by the registry under control of the Meta-Web server, which then builds a results page. The results pages is then forwarded to the user's Web browser.

BACKGROUND OF THE INVENTION

1. Technical Field

The invention relates to knowledge. More particularly, the invention relates to a system for organizing knowledge in such a way that users can find it, learn from it, and add to it as needed.

2. Description of the Prior Art

There is widespread agreement that the amount of knowledge in the world is growing so fast that even experts have trouble keeping up. Today not even the most highly trained professionals—in areas as diverse as science, medicine, law, and engineering—can hope to have more than a general overview of what is known. They spend a large percentage of their time keeping up on the latest information, and often specialize in highly narrow sub-fields because they find it impossible to keep track of broader developments.

Education traditionally meant the acquisition of the knowledge people needed for their working lives. Today, however, a college education can only provide an overview of knowledge in a specialized area, and a set of skills for learning new things as the need arises. Professionals need new tools that allow them to access new knowledge as they need it.

The World Wide Web

In spite of this explosion of knowledge, mechanisms for distributing it have remained pretty much the same for centuries: personal communication, schools, journals, and books. The World Wide Web is the one major new element in the landscape. It has fundamentally changed how knowledge is shared, and has given us a hint of what is possible. Its most important attribute is that it is accessible—it has made it possible for people to not only learn from materials that have now been made available to them, but also to easily contribute to the knowledge of the world in their turn. As a result, the Web's chief feature now is people exuberantly sharing their knowledge.

The Web also affords a new form of communication. Those who grew up with hypertext, or have otherwise become accustomed to it, find the linear arrangement of textbooks and articles confining and inconvenient. In this respect, the Web is clearly better than conventional text.

The Web, however, is lacking in many respects.

It has no mechanism for the vetting of knowledge. There is a lot of information on the Web, but very little guidance as to what is useful or even correct.

There are no good mechanisms for organizing the knowledge in a manner that helps users find the right information for them at any time. Access to the (often inconsistent or incorrect) knowledge on the Web thus is often through search engines, which are all fundamentally based on key word or vocabulary techniques. The documents found by a search engine are likely to be irrelevant, redundant, and often just plain wrong.

The Web knows very little about the user (except maybe a credit card number). It has no model of how the user learns, or what he does and does not know—or, for that matter, what it does and does not know.

A Comparison of Knowledge Sources

There are several aspects to how learners obtain knowledge—they might look at how authoritative the source is, for example, or how recent the information is, or they might want the ability to ask the author a question or to post a comment. Those with knowledge to share might prefer a simple way to publish that knowledge, or they might seek out a well-known publisher to maintain their authority.

While books and journals offer the authority that comes with editors and reviewers, as well as the permanence of a durable product, the Web and newsgroups provide immediacy and currency, as well as the ability to publish without the bother of an editorial process. Table “A” is a summary of the affordances of various forms of publishing.

Corporate and Government Needs

For institutions, corporations, and governments, failure to keep track of knowledge has consequences that are quite different from those for an individual. Often, institutions make a bad decision due to lack of knowledge on the part of those at the right place and at the right time, even though someone else within the institution may actually hold the relevant knowledge.

The consequences of not having the right knowledge at the right place and time can be very severe: doctors prescribing treatments that are sub-optimal, engineers designing products without the benefit of the latest technical ideas, business executives making incorrect strategic decisions, lawyers making decisions without knowledge of relevant precedents or laws, and scientists working diligently to rediscover things that are already known—all these carry tremendous costs to society.

The invention addresses the problem of providing a system that has a very large, e.g. multi-petabyte, database of knowledge to a very large number of diverse users, which include both human beings and automated processes. There are many aspects of this problem that are significant challenges. Managing a very large database is one of them. Connecting related data objects is another. Providing a mechanism for creating and retrieving metadata about a data object is a third.

In the past, various approaches have been used to solve different parts of this problem. The World Wide Web, for example, is an attempt to provide a very large database to a very large number of users. However, it fails to provide reliability or data security, and provides only a limited amount of metadata, and only in some cases. Large relational database systems tackle the problem of reliability and security very well, but are lacking in the ability to support diverse data and diverse users, as well as in metadata support.

The ideal system should permit the diverse databases that exist today to continue to function, while supporting the development of new data. It should permit a large, diverse set of users to access this data, and to annotate it and otherwise add to it through various types of metadata. Users should be able to obtain a view of the data that is complete, comprehensive, valid, and enhanced based on the metadata.

The system should support data integrity, redundancy, availability, scalability, ease of use, personalization, feedback, controlled access, and multiple data formats. The system must accommodate diverse data and diverse metadata, in addition to diverse user types. The access control system must be sufficiently flexible to give different users access to different portions of the database, with distributed management of the access control. Flexible administration must allow portions of the database to be maintained independently, and must allow for new features to be added to the system as it grows.

It would be advantageous to provide a system to organize knowledge in such a way that users can find it, learn from it, and add to it as needed.

SUMMARY OF THE INVENTION

In a preferred embodiment, the invention dynamically generates content and presentations for a user by modifying conventional content, e.g. rendering, restructuring, filtering, or supplementing such content, based on information, e.g. annotations, stored in a database. The invention, referred to as the Meta-Web, allows a user at a Web browser, which may be any standard Web browser supported by a standard computing platform, posits a query that is routed to a Meta-Web server. The Meta-Web server routes the query to a search engine that returns search results to the Meta-Web server. The Meta-Web server then routes the results to a Meta-Web registry that, based on the search results and the content of the registry returns annotations and other meta-data to the Meta-Web server. The Meta-Web server uses the annotations and/or other meta-data to generate and route annotated pages to the browser and the user may then explore the results within the annotated pages, for example by clicking on a URL within the annotated pages.

Unique to the invention is the provision of the registry that receives the search results and provides annotations and/or other information to the Meta-Web server. The registry may also accumulate knowledge, meta-knowledge that was created at a time of entry of such knowledge, and meta-knowledge in the form of one or more annotations that accumulate over time, where the annotations include any of, but are not limited to, usefulness of said knowledge, additional user opinions, certifications of veracity of said knowledge, reputation (which may be based on a formal reputation system), commentary by users, and connections between the knowledge and other units of knowledge.

To create the annotated pages, the Meta-Web server either combines both the search results and information from the registry, or operates upon the search results in accordance with information contained in the registry. The search results are thus augmented or modified by the registry information under control of the Meta-Web server, which then builds the annotated pages. The annotated pages are then forwarded to the user's Web browser.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 is a block schematic diagram showing the architecture of the Meta-Web facility disclosed herein. In operation, a user at aWeb browser10, which may be any standard Web browser supported by a standard computing platform, posits a query (1000) that is routed to a Meta-Web server16. The Meta-Web server routes the query (1006) to a search engine that returns search results (1008) to the Meta-Web server. The Meta-Web server then routes the results (1010) to a Meta-Web registry (14) that, based on the search results and the content of the registry returns annotations and/or other meta-data (1012) to the Meta-Web server. The Meta-Web uses the annotations and/or other meta-data to generate and route annotated pages (1014) to the browser, and the user may then explore the results within the annotated pages, for example by clicking on a URL within the annotated pages (1004).

Unique to the invention is the provision of theregistry14 that receives the search results (1010) and provides annotations (1012) and/or other information to the Meta-Web server. The registry may also accumulate knowledge, meta-knowledge that was created at a time of entry of such knowledge, and meta-knowledge in the form of one or more annotations that accumulate over time, where the annotations include any of, but are not limited to, usefulness of said knowledge, additional user opinions, certifications of veracity of said knowledge, reputation (which may be based on a formal reputation system), commentary by users, and connections between the knowledge and other units of knowledge. Such connections comprise typed links between registry objects, where such links may comprise, for example, relationships, such as a person's role in an organization or a place where a person lives, and such objects may comprise, for example, representations of products, people, places, categories, events, organizations, roles, documents, portions of documents, certifications, ratings, dates, and times.

Accordingly, the presently preferred embodiment of the invention comprises four elements, i.e. a standard Web browser and a standard search engine, which are well known to those skilled in the art, and the registry and Meta-Web server. The registry associates metadata with objects, while the Meta-Web server creates Web pages dynamically, which are then sent to the user's Web browser for viewing by the user. While a Web browser is described herein in connection with the presently preferred embodiment, those skilled in the art will appreciate that other access facilities may be used to practice the invention. As well, the search engine may comprise any type of data access facility. Key to the invention is the provision of the Meta-Web server and registry. Further, while the Meta-Web server and registry are discussed herein as separate elements, their functionality may be combined into a single element. Likewise, their functionality may be dispersed broadly across several elements. For example, a knowledge base comprising knowledge, meta-knowledge that was created at a time of entry of said knowledge, and meta-knowledge in the form of one or more annotations that accumulate over time, the annotations including any of, but not limited to, usefulness of said knowledge, additional user opinions, certifications of veracity of said knowledge, commentary by users, and connections between said knowledge and other units of knowledge may comprise an element of the invention, see U.S. patent application Ser. No. 10/474,155, filed 10 Apr. 2002.

The Meta-Web server as presently embodied creates two types of Web pages, both of which are described in the discussion below and in the Figures accompanying that discussion. One of the Web pages is a Web page that consists of search results with annotations. The other type of Web page is a Web page that consists of a content page with an annotation tool, such as an annotation bar at the side of the results page. In the preferred embodiment, the annotation bar is incorporated into a standard Web browser, but in other embodiments it may be part of a separate Meta-Web application which runs on the user's computer, or it may be an element that is spawned by operation of the user's Web browser, such as a Java applet or JavaScript.

Content displayed to the user is dynamically extracted from the registry by the Meta-Web server. Known techniques for displaying this information include framing, HTML, cascading style sheets, and the like. As discussed in detail below, the architecture herein disclosed provides annotations, search results, and other information in a standard Web browser, as well as a suite of tools for interacting therewith.

The Meta-Web server constructs a search query page which includes a field into which a user can enter one or more search terms. Standard searching techniques, such as Boolean operations, are supported. The query page is delivered to the user's Web browser as a search form. The search form may resemble well known search forms, such as those provided by Google® or it may be presented in any other appropriate format.

When the user enters a query into the search form, the query is forwarded to the search engine by the Meta-Web server. In the preferred embodiment, a user query is processed by the Meta-Web server. Thus, a Web page is constructed by the Meta-Web Server in response to the query when a query is directed to the Meta-Web server from the user via the user's Web browser. Rather than providing results from the search engine directly to the user, the Meta-Web server examines the search results and then performs a look-up in the registry to determine if there are annotations or other information associated with the search results that might be used, for example, to order the results in terms of relevance or other orderings. Likewise, the Meta-Web server may consult the registry prior to positing the query to the search engine. The Meta-Web server may then modify the query or search space and, thereafter, submit the query to the search engine.

Any annotations or other metadata found in the registry may be added to the search results. The Meta-Web server then dynamically constructs a presentation for the user which is returned to the user. The form of the presentation may be controlled by a preference set by the user in the user's Web browser, based upon a user profile stored in the registry, or any combination thereof.

Metadata may be used by the Meta-Web server to check a query term in the registry and determine if there is a prepared way of presenting the data in connection with the term. For example, if there is a common term, it may be determined that the registry has a standard presentation or query results for that term, and that that presentation is preferred over other presentations. Thus, as an alternative to dynamic assembly of the Web page, the registry may provide the Meta-Web server with a preformed response for the query.

One embodiment of the invention provides a relevance button that may be displayed to the user to create a display item which explains the relevance of a term.

In another embodiment, the user may select an item and instead of returning the Web page to the user, that aspect of the search would be framed in the Web page with an annotation bar as discussed above. Thus, the Meta-Web server adds the annotation bar to the Web page to provide the user with the ability not only to comment on relevance or usability of the search result, but to add annotations as desired. Such annotations are then stored in the registry for further use. The annotations are thereafter linked to that user's search space so that further queries by the user bring up the annotations. Further, the annotations may be linked for all uses of that term so that queries by other individuals also produce the annotations entered by the user through the annotation bar. In this way, a community of annotations is assembled which is associated with a particular query term or search result. These aspects of the invention are discussed in greater detail below.

Thus, the presently preferred embodiment of the invention provides selected content within a frame and provides additional frames for annotations, as well as a tool bar for entering and editing annotations. The Meta-Web server dynamically creates the frame for this page and collects the content and annotations to create the complete page. In another embodiment, HTML or XML may be used to accomplish a similar purpose. Additionally, the Meta-Web server may incorporate active components, such as JavaScript or Java applets to provide additional functionality to the user during the annotation process, and may also employ cascading style sheets.

If the content selected by a user relates to a product, i.e. the URL selected by the user leads to a product node, then the Meta-Web server can perform an independent search to collect data with regard to that particular product and dynamically create a Web page for the user that includes information collected in real time. Alternatively, the additional information may be associated with the product in the registry and the Meta-Web server associates the registry information with the product.

Various schemes are envisioned by which the registry, under direction of the Meta-Web server, may be independently updated to refresh or enhance this information. For example, a particular product may be the subject of additional independent searching under control of the Meta-Web server when a certain number of requests are made for a particular product, or when a particular interval has elapsed since the last query concerning the product. Further, independent events, such as discontinuation of a product, may trigger Meta-Web server activities.

The Meta-Web server may identify products within a Web page provided to a user as a result of a user's request for content. Thus, the Meta-Web server identifies product terms or other terms in a page of content, for example by highlighting or underlining, indicating that additional information is available to the user for those products or terms. For example, the user may be performing a search for a particular class of products and within the content a particular product is mentioned. If that product is highlighted, then the user is made aware that the Meta-Web server has identified related information in the registry. The user may then select that highlighted term and the information in the registry is then provided to the user.

For example, if the name of a product is identified, a product node may be selected and annotations associated with it may be provided to the user. Further, the Meta-Web server may provide a filter for those annotations to determine which annotations are of interest to the user, depending on the user profile or user preferences. These annotations can include offers by various merchants to sell the product and other information that may be of interest in connection with the product.

In the event of a filter being applied, the filter may be based on a user profile that may be stored in one of several places. For example, a Web site visited by the user could store a cookie related to the user. In this case, the user could automatically be logged in to the Meta-Web server or at a site being visited, all as a result of a cookie. The Meta-Web server could also keep a profile of the user in a separate database or it could use the registry database. The profile itself may comprise, for example, trusted reputation systems (see, for example, U.S. Provisional Patent Application entitled “Reputation System,” Attorney Docket No. APPL007CI2PR, filed Dec. 12, 2003, U.S. Serial No. not yet assigned), preferred vendors and areas of specific user competence, interest, or understanding.

InFIG. 2, asubject field20 is provided which includes a portion into which the user may enter a search query. When the user has finished composing the query, the user may select thefind button22, and the query is then passed to the Meta-Web server where it is executed.

The invention, also includes anannotation bar21, as discussed above, which is dynamically added to any content, such as search results, that is served to the user by the Meta-Web server. The annotation bar may include user-actuated buttons which provide such functions as allowing the user to comment24, askquestions26, indicate that the information is relevant27, or indicate that the information is not relevant28. Such buttons may be, for example, special local tools embedded in a browser or part of a separate local tool application, or, they may be incorporated into a modified results page.

The invention is envisioned as having many applications. One application of the invention concerns a product purchase, where the user is looking to buy a product on-line after getting information about it. In this example, the user types in a search expression in thesubject field20. In the example ofFIG. 2, the user is looking for information on a flat screen TV.

FIG. 3 is a screen shot showing the results provided to the user in response to the query for a flat screen W. The results are sorted in a way that is personalized for the user. Thus, various icons may be provided near the results. As shown inFIG. 3, the entry “Television Shopping Review/Video/TV & HDTV” is accompanied by anicon31 that appears inFIG. 3 to be darker, while the entry “Net-TV vs. Sony Panasonic digital flat screen TV's pure plasma” is accompanied by anicon32 that appears to be lighter. The significance of the various icons is discussed below. If the user selects thedarker icon31, then a pop-upwindow40 provides information regarding the relevancy to the user of the search result, as shown inFIG. 4.

As shown inFIG. 5, if the lighter icon is selected, then a pop-upwindow50 also shows relevancy of the search result, but the lighter color indicates that the search results include something of personal interest to the user, such as an endorsement by a personal friend. This can be seen in the pop-upwindow50 where it is indicated that the document was recommended because “Stewart Brand likes it.” In this example, Stewart Brand is a friend of the user. The assembly of the information into this format is performed by the Meta-Web server based upon the combining of information contained in the registry and the search results, as described above.

While the examples herein show icons which indicate relevancy by having lighter or darker intensity, the context of indication provided by the icons and the constituency of the icons is a matter of choice for those skilled in the art. Thus, the icons may flash, may be of different colors, may of different shapes, and the like. Further, a user may be alerted by device other than icons, such as audible beeps, and the like.

FIG. 6 is a screen shot in which the user has selected one of the search results60 from the list ofresults30, seeFIG. 3. Variousgray icons61 are shown at the right hand side of the display. The upper icons refer to the entire document and includerelevancy62,information63, and buy64. The bottom icons relate to a portion of the document, for example a user highlighted portion of the document, and include the availability ofFAQs65,additional information66, and an option to buy67 the product.

InFIG. 7, the user has selected theFAQs button65 and a pop-upwindow70 provides answers to Frequently Asked Questions. The FAQs associated with the document concern that part of the document which is highlighted by theuser71. Thus, the invention contemplates that the user can select portions of documents, which are then used by the Meta-Web server to identify annotations in the registry and dynamically generate FAQs relating thereto. Highlighting may also be accomplished automatically by the Meta-Web server, for example, in response to a user query, where the query terms are used to highlight relevant portion of a document.

InFIG. 8, the user has selected the relateditems button66 for the portion oftext80 that is highlighted by the user. As a result, a pop-upwindow81 provides related items and information for the highlighted text. As above, this information is assembled dynamically by the Meta-Web server in connection with the registry.

InFIG. 9, the user selects only thedocuments91 in the related items andinfo window81.

InFIG. 10, selecteddocument100 is displayed with its own annotations. Each document has a unique set of annotations. In the example ofFIG. 10, therelevancy icon62 is illuminated to indicate that there is a comment of personal value or interest to the user.

InFIG. 11, the user has selected therelevancy icon62 and a pop-upwindow110 provides the information of interest to the user. In this case, a window “about this document” is spawned that provides various data gathered from diverse sources that are relevant to the user.

InFIG. 12, the user has highlighted the product “Panasonic PT-45LC12,” as shown by thebox157 which surrounds the product name. The user has also selected acomment icon120 which spawns acomment window121 for the selected product. In this case, a message from a personal friend is displayed. The comment is associated with a product name. Note that the friend in this case has annotated the product but not the particular document that the user is currently viewing. Here, the Meta-Web server has linked Stewart Brand's comment about the product to the product itself, and it has linked the product to the document, as well as to Stewart Brand and to the current user, to display the annotation shown. Thus, various connections have been formed by the Meta-Web server based on the personal information of the user and other information, all of which reside in the registry or within the realm of resources available to the Meta-Web server.

InFIG. 13, the user has selected aninformation icon130 which spawns a pop-upwindow131 that allows the user to look at information about the product that has been obtained from diverse sources.

InFIG. 14, the user has selected a relateditems icon66. The Meta-Web server then spawns arelated items window140 in which the user finds a product node for the user highlighted product, as discussed above. The product node is an abstract Meta-Web object that is constructed by the Meta-Web out of all the information relating to the product. In this case, the node is a ranked list of information.

As shown inFIG. 15, the user selects the item <Product Node: Panasonic PT-45LC12>156 from the related items window.

FIG. 16 is a display that shows a Meta-Web object150 which is a representation of a product node that is dynamically created by the Meta-Web to group together all the information relating to a product. In the example ofFIG. 15, the user interface had been tailored for a particular user through user profile and preference information. Those skilled in the art will appreciate that any of standard and personal formats may be provided for the display. In the example ofFIG. 16, a “change my window”button151 is provided to allow the user to change the appearance of the information. By selecting the “change my window” button the user's “my window”presentation152 may be changed.

If the user selects the manufacturerspecifications sheet button153, the manufacturer'sspecification sheet162 is displayed (seeFIG. 17). The annotations discussed above are associated with the manufacturers specifications sheet as well.

InFIG. 18, the user has selected thebuy button64 and can enter into a personalized purchase transaction to bring the user to a preferred vendor or list of vendors. In various embodiments in the invention, the user's wallet or other personal information may be linked to the Meta-Web server such that the user's purchase transaction may proceed in an automated fashion.

A further example of the invention is concerned with an information-seeking problem where the user is looking to find information about a more complex product or service. In this example (seeFIG. 19) the user is interested in LASIK eye surgery and enters that term into thesearch field20.

As shown inFIG. 20, a screen similar to that shown inFIG. 3, described above, is assembled by the Meta-Web server and returned to the user, except in this case theresults190 relate to the user's query with regard to LASIK and the results have been ordered with regard to relevance to the user.

As shown inFIG. 21, the user chooses thefirst document200 in the results set. The selecteddocument210, seeFIG. 22, turns out to be a technical paper on eye surgery, but the user is not interested in this result. Rather than go back to the results screen, the user selects the “Don't like it”button28, seeFIG. 23. This action updates the user's profile via the Meta-Web server and takes the user back to the results screen, seeFIG. 24. The Meta-Web server has used the updated user profile in this case to re-write theresult list198. Accordingly, the user now sees a different results screen with documents that are more likely to be useful. The user selects the first document230 (FIG. 25). The selected document240 (seeFIG. 26) is displayed. Note that there are annotations available for the document as indicated by the icons at the right side of the document.

As shown onFIG. 27, the user has scrolled to theend250 of the selecteddocument240. The user selects the comment button24 (FIG. 28). This allows the user to add a comment to the document. A pop-up window (FIG. 29) is spawned to ask the user to select the text which comprises an excerpt of the document that is to be associated with his comment. As shown inFIG. 30, the user selects the text document indicated by drawing abox280 around the text. The user then enters his comment290 (FIG. 31). Next, the user submits his comment to the Meta-Web server by selecting a submit button300 (FIG. 32) and the registry is updated to include the user comments. Thecomment icon120 is now highlighted to show that a comment of personal interest has been entered by the user (FIG. 33).

InFIG. 34, the user is about to ask a question related to the document. In this case, the user selects theask button26. The user is informed that the question with be forwarded to the author331 (FIG. 35). Other documents may have different mechanisms for dealing with questions, in addition to forwarding the question to the author.

By selecting theask button26, the Meta-Web server spawns anask window330 into which the user may enter his question (FIG. 36). The user asks hisquestion340 and submits it to the Meta-Web server by selecting theask button341.

As shown inFIG. 37, the user selects thebuy button64 and the Ray-Ban Ad350 on the left side of the display is highlighted. The user is not interested in sun glasses, so he makes another choice.

As shown inFIG. 38, the user selects anotherbuy button360 and theword LASIK361 in the text is highlighted. Because the user is interested in LASIK, rather than Ray-Ban, the user selects the buy button associated with LASIK. Thus, multiple instances of buy buttons and other buttons may be presented to the user on the right hand side to help the user judge the relevancy of the particular portion of the document. The user's choice in selecting LASIK is recorded in the registry by the Meta-Web server and this information may be used in the future to provide more relevant information to the user and/or to groups of users.

As a result of selecting thebuy button360, the user is presented with a list of vendors370 (FIG. 39). The list of the vendors is a results screen that is sorted in a personalized way. As with other result screens, the relevancy of the results are displayed by various types of icons. InFIG. 39, some icons appear darker while others appear lighter.

As shown inFIG. 40, the user selects thepersonal interest icon380. In this example the Meta-Web server has brought together a number of pieces of information to make its recommendation. As shown in therelevancy window381, the vendor is “Maloney Vision Institute,” Dr. Maloney is associated with the vendor, Dr. Maloney is rated highly by Dr. Szabo, and Dr. Szabo is rated highly by the user and his personal physician. Also indicated is that the vendor is covered under the user's medical insurance provider.

As shown inFIG. 41, the vendor has an associatedWeb site390 and the user selects the Web site. As a result, the vendor'sWeb site400 is displayed to the user, seeFIG. 42.
