Abstract

A unique system and method that facilitates providing customized search results for a particular user. The system and method involve tracking user interactions with respect to a list of search results for a given query. In particular, click content, click order, and time stamp data can be collected for each submitted query on a per-user basis. Analysis of the collected data can facilitate inferring the user'"'"'s context or intention with respect to the submitted query to improve the relevancy of returned search results. In addition, the presentation or appearance of the search results can vary according to user preferences, user profile data, or user interests. Thus, different users who submit similar queries using the same or similar terms can receive different sets of search results.

Claims

1. A ranking system that facilitates improving the relevancy of search results for a particular user comprising:

an interaction tracking component that monitors and tracks user interactions with respect to a given set of search result items;

an analysis component that examines the user interactions of the particular user for the given set of search result items; and

a ranking component that re-ranks one or more search result items in the given set based at least in part on the user interactions to facilitate customizing search results for the particular user.

2. The system of claim 1, wherein the analysis component evaluates at least a portion of user data to facilitate determining at least one of user context or user intention with respect to a given set of search terms.

3. The system of claim 2, wherein the user data comprises demographic information, personal interests, preferences, and previously submitted searches.

4. The system of claim 2, wherein the analysis component associates the user interactions with respect to the given set of search terms.

5. The system of claim 1 further comprising a scoring component that adjusts at least one of scores or weights of one or more items from the set of search result items according to the user interactions to affect a ranking of the items.

6. The system of claim 1, wherein user interactions comprise clicking on any one search result item, clicking on a back button, clicking on a next button, skipping one or more search result items, refining search terms, and submitting a new set of search terms.

7. The system of claim 1, wherein the tracking component comprises at least one of a click recorder, voice recognition module, and a time counter.

8. The system of claim 7, wherein the click recorder tracks at least one of click content and click order to facilitate improving relevancy of search result items returned to the user.

9. The system of claim 1, wherein the tracking component is located on a server and sends a persistent cookie to a client machine for each new submission of search terms to facilitate tracking the user'"'"'s response to one or more result items returned for each respective set of search terms.

10. The system of claim 1 further comprising:

a search engine that generates one or more search result items for a given query; and

one or more filter components located on a client that filter the search result items based on user data to customize at least one of the following;

appearance and presentation of at least one search result item and order of the search result items.

11. A method that facilitates improving the relevancy of search results for a particular user comprising:

tracking user interaction with respect to the one or more search result items;

analyzing at least a portion of content of the one or more search result items based on the user interaction with the items and user data; and

fine-tuning search results for a given set of search terms on a per-user basis based at least in part upon user interaction data for each particular user, wherein fine-tuning comprises re-ordering the search result items in a customized manner according to the user'"'"'s interaction with them and the user'"'"'s personal data.

12. The method of claim 11, wherein tracking user interaction comprises monitoring user behavior, recording click order and corresponding click content, recording skipped items, measuring elapsed time between clicks, and recording items that are at least one of printed, saved, bookmarked, or emailed.

13. The method of claim 11, wherein tracking user interaction comprises creating a persistent cookie on a client machine with each new set of search terms submitted for searching.

14. The method of claim 13, wherein the persistent cookie captures click data and a timestamp for each click.

15. The method of claim 11, wherein analyzing at least a portion of the content comprises analyzing at least a title of one or more of the items in conjunction with user interaction data and user data.

16. The method of claim 11, wherein fine-tuning search results comprises adjusting at least one of a score or a weight of each respective result item according to at least one of tracked data or user data.

17. The method of claim 11 further comprises aggregating user interaction data for the set of search terms from a plurality of users in order to facilitate improving search results returned to the plurality of users for the set of search terms.

18. The method of claim 11 further comprises filtering at least a portion of the search results items for at least one of presentation, source, and content according to user filter settings.

19. The method of claim 11 further comprises inferring at least one of user intention or user context with respect to the set of search terms based on the user interaction data and user data to facilitate the fine-tuning of future searches.

20. A ranking system that facilitates improving the relevancy of search results for a particular user comprising:

means for tracking user interactions with respect to a given set of search result items;

means for examining the user interactions of the particular user for the given set of search result items; and

means for re-ranking one or more search result items in the given set based at least in part on the user interactions to facilitate customizing search results for the particular user.
