Abstract

A method for contextualizing search results is disclosed. The method includes performing a traditional web query that returns a set of result pages, using collaborative filtering techniques to generate a set of predicted pages, comparing the set of predicted pages with the set of result pages, and ranking the set of result pages so that result pages that are also included in the set of predicted pages are ranked higher than those that are not. Methods herein also contemplate using the search history of the user or others to refine the results of searches.

Claims

1. A method, comprising:

receiving a search request;

performing a traditional web query that returns a set of result pages;

using collaborative filtering techniques to generate a set of predicted pages;

comparing the set of predicted pages with the set of result pages; and

adjusting the set of result pages based upon the set of predicted pages.

2. The method of claim 1, wherein each of the set of result pages comes from a server, and wherein using collaborative filtering techniques includes obtaining a case base for at least one of the servers from which a result page came.

3. The method of claim 2, wherein obtaining a case base includes generating the case base.

4. The method of claim 2, wherein obtaining a case base includes accessing the case base.

5. The method of claim 2, wherein using collaborative filtering techniques to generate a set of predicted pages includes:

generating a list of viewed pages visited by a source of the request within a finite time period before the search; and

comparing the list of viewed pages with the case base for the at least one server to generate a list of predicted matches.

6. The method of claim 5, wherein the finite time period is a predetermined value.

7. The method of claim 5, wherein the finite time period is received from the source of the search request.

8. The method of claim 1, wherein using collaborative filtering techniques includes obtaining a case base for the server from which the web query originated.

9. The method of claim 8, wherein using collaborative filtering techniques to generate a set of predicted pages includes:

generating a list of viewed pages visited by a source of the request within a finite time period before the search; and

comparing the list of viewed pages with the case base for the server from which the web query originated.

10. The method of claim 1, wherein adjusting the set of result pages includes ranking the set of result pages so that result pages that are also included in the set of predicted pages are ranked higher than they would have been otherwise.

11. The method of claim 1, wherein adjusting the set of result pages includes highlighting any of the result pages that are the same as the predicted pages.

12. The method of claim 1, wherein adjusting the set of result pages includes adding predicted pages that aren'"'"'t part of the result pages to the search results as potential matches.

13. A method for performing a search of the web, comprising:

receiving a search request;

performing a traditional web query that returns a set of result pages;

defining a time period prior to the search;

determining what pages were visited by the source of the search request during the time period prior to the search.

adjusting the set of result pages based upon the set of viewed pages.

14. The method of claim 13, wherein the finite time period is a predetermined value.

15. The method of claim 13, wherein the finite time period is received from the source of the search request.

16. A method for personalizing a web search, comprising:

retaining a record of a user'"'"'s search history; and

adjusting the results of the web search in view of the user'"'"'s search history.

17. The method of claim 16, further comprising retaining information on pages that link to at least one page in the user'"'"'s search history.

18. The method of claim 16, wherein retaining a record of a user'"'"'s search history includes writing the user'"'"'s search history to a cookie on a computer with which the user connects to the web.

19. The method of claim 16, wherein retaining a record of a user'"'"'s search history includes storing the history in a database remote from the user.

20. The method of claim 16, further comprising comparing the user'"'"'s search history with the search history of other user'"'"'s to determine a set of predicted pages, and wherein the predicted pages are used to adjust the results of the web search.

21. The method of claim 16, wherein the results come are listed in a particular order and where adjusting the results includes reranking the set of result pages in view of the user'"'"'s search history.

22. A method for personalizing a web search, comprising:

retaining a record of previous searches conducted by the search engine;

determining a set of predicted pages for particular search terms based upon the record of previous searches; and

adjusting the results of the web search by the predicted pages.
