Abstract

The relevancy of search results are improved by exploiting changes in data related to information access. Parameter varying aspects of parameter varying data associated with document access are leveraged to provide enhanced ranking of document. As an aspect of the parameter varies, a rank can be accomplished, producing multiple ranks for a given set of parameter varying data. Parameters such as time, user preferences, popularity, and/or user demographics and the like can be utilized as parameter varying data. Thus, in general, single or multiple varying aspects of the parameters can be employed to produce a set of ranks comprising one or more rankings of document. This technique can be employed with static rankers, dynamic rankers, and/or ranker training data and the like to produce higher relevancy search results, increasing user satisfaction.

Claims

1. A method for ranking documents, comprising:

obtaining parameter varying data related to at least one document; and

employing a parameter varying aspect of the parameter varying data to rank the document.

2. The method of claim 1, wherein the parameter varying data comprises time varying data and the parameter varying aspect comprises a time varying aspect.

3. The method of claim 2 further comprising:

utilizing the time varying data to provide time varying static ranking of documents.

4. The method of claim 1, wherein the parameter varying data comprises user demographic varying data and the parameter varying aspect comprises a demographic varying aspect.

5. The method of claim 1 further comprising:

utilizing the parameter varying data to provide static ranking of documents.

6. The method of claim 5, wherein the parameter varying data comprises individual user varying data and the parameter varying aspect comprises an individual user varying aspect.

7. The method of claim 5 further comprising:

utilizing parameter varying data to construct multiple document ranks.

8. The method of claim 1 further comprising:

utilizing the parameter varying data to provide dynamic ranking of documents.

9. The method of claim 1 further comprising:

incorporating the parameter varying data directly into the ranking of the documents.

10. The method of claim 1 further comprising:

incorporating the parameter varying data into training data utilized for ranking the documents.

11. The method of claim 1, wherein the parameter varying data comprises popularity varying data and the parameter varying aspect comprises a popularity varying aspect.

12. The method of claim 1, wherein the parameter varying data comprises user preference varying data and the parameter varying aspect comprises a user preference varying aspect.

19. A device employing the method of claim 1 comprising at least one selected from the group consisting of a computer, a server, and a handheld electronic device.

13. A system that ranks documents, comprising:

a receiving component that receives parameter varying data that is associated with a document; and

a ranking component that determines a rank for the document based on, at least in part, a parameter varying aspect of the parameter varying data.

14. The system of claim 13, the parameter varying data comprising user demographic, user preference, popularity, and/or time varying data and associated aspects.

15. A static ranking system that employs, at least in part, the system of claim 13 to determine document ranking.

16. A dynamic ranking system that employs, at least in part, the system of claim 13 to determine document ranking.

17. The system of claim 13, the ranking component provides multiple static rankings based on the parameter varying aspect of the parameter varying data.

20. A device employing the system of claim 13 comprising at least one selected from the group consisting of a computer, a server, and a handheld electronic device.

18. A system that ranks documents, comprising:

means for obtaining data with a varying aspect that is related to document access by online users; and

means for utilizing the varying aspect in determining a rank for a document employed in a static and/or dynamic search result ranker.
