Abstract

Techniques for identifying mutual interests between users of a social networking system are disclosed herein. In one embodiment, a method includes identifying, by a social networking system, a content object with which a first user of the social networking system has interacted. The social networking associates a keyword phrase with the first user. The keyword phrase has been previously associated with the content object. The social networking system further determines a mutual interest for the first user and a second user of the social networking system by identifying a match between the keyword phrase associated with the first user with a keyword phrase associated with the second user.

Claims

1. A method comprising:

identifying, by a social networking system, a content object with which a first user of the social networking system has interacted;

associating, by the social networking system, a keyword phrase with the first user, wherein the keyword phrase is associated with the content object; and

determining, by the social networking system, a mutual interest for the first user and a second user of the social networking system by identifying a match between the keyword phrase associated with the first user with a keyword phrase associated with the second user.

2. The method of claim 1, further comprising:

associating the keyword phrase with the content object by conducting a reverse keyword search on the content object.

3. The method of claim 1, further comprising:

notifying the first user or the second user that another user of the social networking system shares the mutual interest.

4. The method of claim 1, wherein the content object has been interacted by an action of the first user suggesting that the first user takes an interest in the content object.

5. The method of claim 1, wherein the second user locates within a geographic region that is specified by the first user.

6. The method of claim 1, wherein keyword phrases associated with the first user includes keyword phrases identified from a user profile of the first user.

7. The method of claim 1, wherein the reverse keyword search receives the content object or an identifier of the content object as an input, and generates a keyword phrase that is related to the content object as an output.

8. The method of claim 1, further comprising:

notifying the first user that another user of the social networking system in close proximity of the first user shares the mutual interest.

9. The method of claim 1, further comprising:

notifying the first user that another user of the social networking system shares the mutual interest, wherein the other user plans to attend an event that the first user plans to attend.

10. A method comprising:

storing a plurality of database entries by a social networking system, wherein the plurality of database entries record relationships between content objects and keyword phrases;

receiving a notification that a first user of the social networking system has interacted with a content object;

identifying a database entry from the plurality of database entries, wherein the database entry records a relationship between the content object and a keyword phrase;

associating, by the social networking system, the keyword phrase with the first user; and

determining, by the social networking system, a mutual interest for the first user and a second user of the social networking system by identifying a match between the keyword phrase associated with the first user with a keyword phrase associated with the second user.

11. The method of claim 10, further comprising:

notifying the first user that another user of the social networking system shares the mutual interest.

12. The method of claim 10, wherein the content object has been interacted by an action of the first user suggesting that the first user takes an interest in the content object.

13. The method of claim 10, wherein the second user locates within a geographic region that is specified by the first user.

14. The method of claim 10, wherein keyword phrases associated with the first user includes keyword phrases identified from a user profile of the first user.

15. The method of claim 10, further comprising:

notifying the first user that another user of the social networking system in dose proximity of the first user shares the mutual interest.

16. The method of claim 10, further comprising:

notifying the first user that another user of the social networking system shares the mutual interest, wherein the other user plans to attend an event that the first user plans to attend.

17. A social networking system comprising:

a user activity track module configured to detect a first user of the social networking system interacting with a content object;

a reverse keyword search engine configured to generate a keyword phrase based on the content object;

an object store configured to record the keyword phrase in a user object for the first user; and

a user match module configured to determine a mutual interest for the first user and a second user of the social networking system by identifying a match between the keyword phrase recorded in the user object for the first user and a keyword phrase recorded in a user object for the second user.

18. The social networking system of claim 17, wherein the user match module is further configured to notify the first user that another user of the social networking system shares the mutual interest.

19. The social networking system of claim 17, wherein the reverse keyword search engine includes a database containing information of relationships between a plurality of content objects and a plurality of keyword phrases.

20. The social networking system of claim 19, wherein the reverse keyword search engine is further configured to update the database by results of a new reverse keyword search.
