Abstract: A content distribution system determines a content selection metric that allows the content distribution system to evaluate whether a content provider maximizes its net content value by stating the true content value of presenting content items by the content distribution system. The content distribution system determines net content values of presented content items and re-performs content selection processes based on modified content value offers. The content distribution system then determines sets of alternative net content values and compares the alternative net content values to the corresponding net content values to determine if the content provider can achieve a greater net content value with a content value offer that does not match the stated content value of presenting the content value. The content distribution system then determines a content selection metric based on the compared net content values and alternative net content values.

Abstract: To generate stories for presentation to social networking system users, one or more story generation engines receives a set of actions of social networking system users. Various story generation engines output stories of different types that collect particular types of actions and arrange the actions in a specified format for presentation. The story generators may avoid selecting the same actions for different stories. Stories generated by the various story generators may be ranked and the ranking used to select stories for presentation to one or more social networking system users.

Abstract: A social data aggregator generates entries of action data describing actions taken by users. A portion of the entries are stored in an action cache to expedite retrieval. To store more recent or relevant entries in the action cache, entries are removed from the action cache based on engagement scores associated with the entries. An engagement score indicates a likelihood of a user requesting content interacting with a notification based on an entry. Entries having the lowest engagement scores or having engagement scores below a threshold are removed from the action cache.

Abstract: A social networking system provides a content feed to a client device associated with the user of a social networking system, the content feed including a plurality of content items. The social networking system identifies one or more missed content items, of the plurality of content items, that were part of the content feed and were not displayed by the client device. The social networking system generates a subsequent content feed that includes one or more content items that have not been previously provided to the client device and a missed feed unit that is associated with the one or more missed content items. In one embodiment, the missed feed unit, when selected, redirects the user to a new page that presents a different content feed including the identified missed content items. The social networking system provides the subsequent content feed to the client device for presentation to the user.

Abstract: A social networking system selects content items previously presented to a user for presentation to the user along with content items that were not previously presented. The social networking system selects candidate content items as previously-presented content items satisfying one or more criteria. One or more indices each associated with one or more attributes are generated that include candidate content items having attributes associated with an index. Candidate content items in an index are ranked based on a likelihood of the user interacting with the candidate content items in the index, and one or more candidate content items are selected from the index for presentation based on the ranking. The candidate content items selected from the index are presented to the user along with additional content items not previously-presented to the user.
