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 of a social networking system. The entries are archived in a number of remote data hosts, with a portion of the entries stored in an action cache to expedite retrieval. The action cache is modified to include relevant entries of action data by selecting the most relevant entries from proxy data aggregators, which identify sets of entries from remote data hosts coupled to the proxy data aggregators based on the relevance of the entries in the remote data hosts. The relevance of an entry is based on an associated engagement score indicating a likelihood of a user requesting content interacting with a notification based on an entry.

Abstract translation: 社交数据聚合器生成描述社交网络系统的用户采取的动作数据的条目。 这些条目存档在多个远程数据主机中，一部分条目存储在动作缓存中以加快检索。 行动缓存被修改为包括行动数据的相关条目，从代理数据聚合器中选择最相关的条目，代理数据聚合器根据远程数据主机中条目的相关性来识别与代理数据聚合器耦合的远程数据主机的条目集 。 条目的相关性基于相关联的参与分数，其指示用户基于条目请求内容与通知进行交互的可能性。

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.
