Abstract

A computer system identifies web pages of interest to a client. The system comprises a cataloging function which defines a hierarchy of subject categories, logically arranges a multitude of web pages in the categories and periodically adds web pages to the categories. The system also comprises a profile building function which receives selections of categories from a user, records the selections and responds with an identification of subcategories of each selected category. The user can make further selections from the subcategories. Alternately, the user makes a key word search and then selects data web pages from the results of the search. The profile building function records the categories of the data web pages selected by the user. Next, the user requests a list of recently added web pages of interest to the user. In response, the system identifies recently added web pages from the categories previously selected by the user and from the categories of the data web pages previously selected by the user.

Claims

1. A computer network for identifying web pages of interest to a user, said network comprising:

a server computer comprising

cataloging means for defining a hierarchy of subject categories, assigning a multitude of web pages to said categories based on subjects of said web pages and

periodically assigning additional web pages to said categories based on subjects of said additional web pages; and

profile building means, responsive to selection of a category by said user, for identifying other categories that descend from the selected category, responsive to selection of one of said other categories by said user, for identifying still other categories that descend from said one other category, for recording said selected categories and responsive to a request by said user to identify web pages of interest, for identifying hot links to web pages assigned to said selected categories; and

a client computer physically distanced from but coupled to said server computer and having a web browser which displays web pages defining said hierarchy, permits said user to make said selections of categories and request the identity of web pages of interest, displays the identified hot links and permits the user to select the identified hot links.

2. A computer network as set forth in claim 1 wherein said categories include other hot links to respective data web pages, said other hot links being displayed by said web browser within web pages that concurrently display said categories, said identified hot links and said other hot links bypassing said server computer, whereby when said user selects said identified hot links and said other hot links respective htmls are sent from other server computer(s) to said client computer bypassing the first said server computer.

3. A computer network as set forth in claim 2 wherein web pages defined by said identified hot links and said other hot links include hot links to still other web pages and when said user selects said still other hot links from said client computer respective htmls are sent from other server computer(s) to said client computer bypassing said first server computer.

4. A computer network as set forth in claim 2 wherein said user requests an identity of recently added web pages from the categories previously selected by said user but not the identity of other web pages added prior to said recently added web pages, and said server computer complies with said request for recently added web pages.

5. A computer network as set forth in claim 1 wherein

said profile building means is logically or physically interposed between said cataloging means and said user;

said web browser concurrently displays said categories with other hot links to respective web pages; and

said profile building means provides a web address of said profile building means for said other hot links and said identifying hot links so that when said user selects said other hot links and said identifying hot links, said selections for said other hot links and said identifying hot links are sent to said profile building means, and said profile building means sends respective fetch requests to other server computer(s) that store web pages corresponding to said other hot links and said identified hot links.

6. A computer network as set forth in claim 5 wherein additional hot links within said web pages corresponding to said other hot links and said identified hot links were assigned to respective categorizes before said user selects them, and when said user selects said additional hot links said profile building means records the respective categories, and when said user requests an identity of web pages of interest, said profile building means identifies hot links to web pages from said selected categories and hot links to other web pages in categories in which said additional web pages were categorized.

7. A computer network as set forth in claim 1 wherein said profile building means responds to said request for web pages of interest by identifying recently added web pages from the selected categories and not identifying other web pages added prior to said recently added web pages.

8. A method for identifying web pages of interest to a user operating a client computer linked to a server computer, said method comprising the steps of:

said server computer defining a hierarchy of subject categories, assigning a multitude of web pages to said categories based on subjects of said web pages and subsequently assigning additional web pages to said categories based on subjects of said additional web pages;

said client computer fetching and displaying web pages defining said hierarchy and permitting said user to select a plurality of said categories;

said server computer, in response to selection of each of said plurality of categories, identifying other categories that descend from the selected category and recording said selected categories;

said client computer permitting said user to request web pages of interest to said user;

said server computer, in response to said request by said user to identify web pages of interest, identifying hot links to web pages assigned to said selected categories; and

said client computer displaying web pages containing said hot links and permitting said user to make said selections of identified hot links.

9. A method as set forth in claim 8 wherein

said categories include other hot links to respective data web pages;

and

said client computer displays said other hot links within web pages that concurrently display said categories, said identified hot links and said other hot links bypassing said server computer, whereby when said user selects said identified hot links and said other hot links respective htmls are sent from other server computer(s) to said client computer bypassing the first said server computer.

10. A method as set forth in claim 9 wherein web pages defined by said identified hot links and said other hot links include hot links to still other web pages and when said user selects said still other hot links from said client computer respective htmls are sent from other server computer(s) to said client computer bypassing said first server computer.

11. A method as set forth in claim 9 further comprising the steps of said user requesting an identity of recently added web pages from the categories previously selected by said user but not the identity of other web pages added prior to said recently added web pages, and said server computer complies with said request for recently added web pages.

12. A method as set forth in claim 8 wherein said server computer responds to said request for web pages of interest by identifying recently added web pages from the selected categories and not identifying other web pages added prior to said recently added web pages.

13. A computer program product for identifying web pages of interest to a user operating a client computer linked to a server computer, said computer program product comprising:

a computer readable medium;

first program instruction means for execution in said server computer to instruct a processor to define a hierarchy of subject categories, assign a multitude of web pages to said categories based on subjects of said web pages and subsequently assign additional web pages to said categories based on subjects of said additional web pages;

second program instruction means for execution in said client computer to instruct a processor to fetch and display web pages defining said hierarchy and permit said user to select a plurality of said categories;

third program instruction means for execution in said server computer to instruct a processor, in response to selection of each of said plurality of categories, to identify other categories that descend from the selected category and record said selected categories;

fourth program instruction means for execution in said client computer to instruct a processor to permit said user to request web pages of interest to said user;

fifth program instruction means for execution in said server computer to instruct a processor, in response to said request by said user to identify web pages of interest, to identify hot links to web pages assigned to said selected categories; and

sixth program instruction means for execution in said client computer to instruct a processor to display web pages containing said hot links and permit said user to make said selections of identified hot links; and

wherein all of said program instruction means are recorded on said medium.

14. A computer program product as set forth in claim 13 further comprising seventh program instruction means for execution in said server computer to instruct a processor to respond to said request for web pages of interest by identifying recently added web pages from the selected categories and not identifying other web pages added prior to said recently added web pages;

and wherein

said seventh program instruction means is recorded on said medium.
