Abstract

In one embodiment, a set of user groups of a social-networking system may be accessed. A first subset of the user groups may be determined for a particular user of the social-networking system, based on one or more filtering criteria. A number of recommendation-source processes may be applied to the first subset to determine a number of second subsets of the first set. Each recommendation-source process may represent a particular recommendation source. The second subsets may be combined into a list of user groups. The list of user groups may be ranked, and sent to the particular user.

Claims

1. A method comprising:

by one or more computing devices, accessing a set of user groups of a social-networking system;

by one or more computing devices, determining a first subset of the user groups for a particular user of the social-networking system based on one or more filtering criteria;

by one or more computing devices, applying a plurality of recommendation-source processes to the first subset to determine a plurality of second subsets of the first subset, wherein each of the recommendation-source processes represents a particular recommendation source;

by one or more computing devices, combining the second subsets into a list of user groups;

by one or more computing devices, ranking the list of user groups; and

by one or more computing devices, sending the list of user groups as ranked to the particular user.

2. The method of claim 1, wherein:

the social-networking system is associated with a plurality of users;

the social-networking system comprises a graph that comprises a plurality of nodes and a plurality of edges connecting the nodes;

some of the nodes each correspond to one of the user groups; and

some of the nodes each correspond to one of the users.

3. The method of claim 1, wherein the particular recommendation source determines the second subset of user groups by comparing the first subset with:

a user group joined by friends of the particular user;

a user group joined by users sharing common membership in another user group with the particular user;

a user group joined by users determined to have a common interest with the particular user;

a user group joined by users having a location or age in common with the particular user;

a user group joined by users having profile information in common with the particular user;

a user group associated with a topic that is associated with the particular user;

a user group having a co-interaction association with another user group associated with the particular user;

a user group having a co-interaction association with a page associated with the particular user;

or

a user group viewed by the particular user.

4. The method of claim 1, wherein the one or more filtering criteria are based at least in part on:

a most recent activity for a user group;

a number of members of a user group;

a most recent writing activity for a user group;

a rate of activities in a user group;

or

a membership type of a user group.

5. The method of claim 3, wherein the rate of activities in the user group comprises:

a rate of posts in the user group over a predetermined period of time;

a rate of comments or likes per post in the user group over a predetermined period of time;

or

a rate of views in the user group over a predetermined period of time.

6. The method of claim 3, wherein the membership type of the user group comprises:

an open user group;

a closed user group;

a secret user group;

a disabled user group;

or

an empty user group.

7. The method of claim 3, wherein the most recent writing activity for a user group comprises a date of a most recent post shared to the user group by a member of the user group.

8. The method of claim 3, wherein the most recent activity for a user group comprises:

a date of a most recent post, like, or comment in the user group;

or

a predetermined number of posts, likes, or comments in the user group over a predetermined period of time.

9. The method of claim 1, wherein the each of the recommendation-source processes determines a predetermined number of user groups for the second subset.

10. The method of claim 1, wherein at least one recommendation source is updated in response to an action on the social-networking system by the particular user, the action comprising:

a new group joined by the particular user;

a view of a group by the particular user on the online social network;

a post shared to the online social network by the particular user;

a second user being added as a friend by the particular user;

a like or comment shared by the particular user;

or

a profile update for the particular user.

11. The method of claim 1, wherein a particular user group is excluded from the first subset based on a language filter.

12. The method of claim 1, wherein a particular user group is excluded from the first subset based on at least one previous list of user groups comprising the particular user group being sent to a user of the social-networking system.

13. The method of claim 12, further wherein the particular user group is excluded from the first subset based on one or more actions of the user of the social-networking system in response to receiving the at least one previous list of user groups.

14. The method of claim 1, wherein a particular user group is excluded from the first subset based on previous activities of the particular user in association with the particular user group.

15. The method of claim 1, wherein a particular user group is excluded from the first subset based on one or more administrative-approval factors for the particular user group.

16. The method of claim 15, wherein the administrative-approval factors comprise:

a number of users waiting to be admitted into the particular user group;

a number of group join requests by the particular user awaiting administrative action;

or

a rejection rate of new members for the particular user group.

17. The method of claim 1, wherein ranking the list of user groups is based at least in part on:

a probability that the particular user will interact with a particular user group;

a social affinity or coefficient of a particular user group with respect to the particular user;

or

a ranking score for a particular user group with respect to the particular user, the ranking score comprising one or more feature scores, wherein the feature scores are based at least in part on one or more characteristics of the user group.

18. The method of claim 17, wherein the ranking score is calculated through a machine-learning process.

19. One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

access a set of user groups of a social-networking system;

determine a first subset of the user groups for a particular user of the social-networking system based on one or more filtering criteria;

apply a plurality of recommendation-source processes to the first subset to determine a plurality of second subsets of the first subset, wherein each of the recommendation-source processes represents a particular recommendation source;

combine the second subsets into a list of user groups;

rank the list of user groups; and

send the list of user groups as ranked to the particular user.

20. A system comprising:

one or more processors; and

a memory coupled to the processors comprising instructions executable by the processors, the processors being operable when executing the instructions to;

access a set of user groups of a social-networking system;

determine a first subset of the user groups for a particular user of the social-networking system based on one or more filtering criteria;

apply a plurality of recommendation-source processes to the first subset to determine a plurality of second subsets of the first subset, wherein each of the recommendation-source processes represents a particular recommendation source;

combine the second subsets into a list of user groups;

rank the list of user groups; and

send the list of user groups as ranked to the particular user.
