Abstract

A method comprises identifying a first user having stored in a database a set of first bookmarks associated with a topic of interest; determining a level of relatedness of a second user to the first user by comparing a first number of overlapping bookmarks that were stored in the database by the second user and that overlap the set of first bookmarks; determining a level of value of the second user to the first user by comparing a second number of related nonoverlapping bookmarks that were stored in the database by the second user, that relate to the topic of interest, and that do not overlap the set of first bookmarks; and presenting at least a portion of the related nonoverlapping bookmarks to the first user.

Claims

1. A method, comprising:

identifying a first user having stored in a database a set of first bookmarks associated with a topic of interest;

determining a level of relatedness of a second user to the first user by comparing a first number of overlapping bookmarks that were stored in the database by the second user and that overlap the set of first bookmarks;

determining a level of value of the second user to the first user by comparing a second number of related nonoverlapping bookmarks that were stored in the database by the second user, that relate to the topic of interest, and that do not overlap the set of first bookmarks; and

presenting at least a portion of the related nonoverlapping bookmarks to the first user.

2. The method of claim 1, further comprising determining whether the first user has more than a threshold number of first bookmarks in the set of first bookmarks associated with the topic of interest.

3. The method of claim 1, wherein the database is a publicly available database.

4. The method of claim 1, wherein the first bookmarks are associated with at least one first tag that indicates the topic of interest.

5. The method of claim 4, wherein the nonoverlapping bookmarks are associated with at least one second tag, and further comprising determining whether the nonoverlapping bookmarks are related to the topic of interest by comparing the at least one first tag to the at least one second tag.

6. The method of claim 1, further comprising determining whether the first number is greater than an overlapping threshold.

7. The method of claim 1, further comprising determining whether the second number is greater than a nonoverlapping threshold.

8. The method of claim 1, further comprising generating an overlap score of the second user to the first user based on the level of relatedness and on the level of value.

9. The method of claim 8, further comprising

determining a level of relatedness of a third user to the first user by comparing a third number of overlapping bookmarks that were stored in the database by the third user and that overlap the set of first bookmarks;

determining a level of value of the third user to the first user by comparing a fourth number of related nonoverlapping bookmarks that were stored in the database by the third user, that relate to the topic of interest, and that do not overlap the set of first bookmarks;

generating an overlap score of the third user to the first user based on the level of relatedness and on the level of value; and

comparing the overlap score of the second user to the overlap score of the third user to determine whether the second user or the third user should be prioritized.

10. The method of claim 9, further comprising presenting the first user a first link to the bookmarks of the second user and second link to the bookmarks of the third user.

11. A system, comprising:

a recommendation manager for identifying a first user having stored in a database a set of first bookmarks corresponding to a topic of interest; and

an overlap determination module for determining a level of relatedness of a second user to the first user by comparing a first number of overlapping bookmarks that were stored in the database by the second user and that overlap the set of first bookmarks, and for determining a level of value of the second user to the first user by comparing a second number of related nonoverlapping bookmarks that were stored in the database by the second user, that relate to the topic of interest, and that do not overlap the set of first bookmarks.

12. The system of claim 11, wherein the recommendation manager determines whether the first user has more than a threshold number of first bookmarks in the set of first bookmarks associated with the topic of interest.

13. The system of claim 11, wherein the database is a publicly available database.

14. The system of claim 11, wherein the first bookmarks are associated with at least one first tag that indicates the topic of interest.

15. The system of claim 14, wherein the nonoverlapping bookmarks are associated with at least one second tag, and wherein the overlap determination module determines whether the nonoverlapping bookmarks are related to the topic of interest by comparing the at least one first tag to the at least one second tag.

16. The system of claim 11, further comprising a related user finder for determining whether the first number is greater than an overlapping threshold.

17. The system of claim 11, further comprising a related user finder for determining whether the second number is greater than a nonoverlapping threshold.

18. The system of claim 11, further comprising an overlap score generator for generating an overlap score of the second user to the first user based on the level of relatedness and on the level of value.

19. The system of claim 18,

wherein the overlap determination module determines a level of relatedness of a third user to the first user by comparing a third number of overlapping bookmarks that were stored in the database by the third user and that overlap the set of first bookmarks;

wherein the overlap determination module determines a level of value of the third user to the first user by comparing a fourth number of related nonoverlapping bookmarks that were stored in the database by the third user, that relate to the topic of interest, and that do not overlap the set of first bookmarks;

wherein the overlap score generator generates an overlap score of the third user to the first user based on the level of relatedness and on the level of value; and

further comprising a recommendation manager for comparing the overlap score of the second user to the overlap score of the third user to determine whether the second user or the third user should be prioritized.

20. The system of claim 19, wherein the recommendation manager enables presenting the first user a first link to the bookmarks of the second user and second link to the bookmarks of the third user.

21. The system of claim 11, wherein the recommendation manager enables presenting at least a portion of the related nonoverlapping bookmarks to the first user.

22. A system comprising:

means for identifying a first user having stored in a database a set of first bookmarks associated with a topic of interest;

means for determining a level of relatedness of a second user to the first user by comparing a first number of overlapping bookmarks that were stored in the database by the second user and that overlap the set of first bookmarks;

means for determining a level of value of the second user to the first user by comparing a second number of related nonoverlapping bookmarks that were stored in the database by the second user, that relate to the topic of interest, and that do not overlap the set of first bookmarks; and

means for presenting at least a portion of the related nonoverlapping bookmarks to the first user.
