12. The computer-implemented method of claim 11 , wherein the ranking algorithm decreases rankings for at least some content items determined by the image classification process to include at least one of memes or food.

13. The computer-implemented method of claim 11 , wherein the ranking algorithm is based on social interaction analysis.

14. The computer-implemented method of claim 13 , wherein the ranking algorithm increases rankings for at least some content items determined by the social interaction analysis to be associated with a current relationship associated with the user account and decreases rankings for at least some content items determined by the social interaction analysis to be associated with a terminated relationship associated with the user account.

15. The computer-implemented method of claim 1 , wherein at least a first content item in the subset of content items is associated with a first time period and wherein at least a second content item in the subset of content items is associated with a second time period.

16. The computer-implemented method of claim 1 , wherein at least a first content item in the subset of content items is associated with a first location and wherein at least a second content item in the subset of content items is associated with a second location.

17. The computer-implemented method of claim 1 , wherein the user account is associated with at least one of a user of a social networking system, an entity associated with the social networking system, a group associated with the social networking system, a post on the social networking system, an application provided via the social networking system, or an event created through the social networking system.
