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.

Abstract translation: 社交网络系统选择先前呈现给用户的内容，以及与之前呈现的内容项目一起呈现给用户。 社交网络系统选择候选内容项目作为满足一个或多个标准的先前呈现的内容项目。 生成与一个或多个属性相关联的一个或多个索引，其包括具有与索引相关联的属性的候选内容项。 基于用户与索引中的候选内容项目进行交互的可能性，对索引中的候选内容项进行排名，并且基于排名从用于呈现的索引中选择一个或多个候选内容项。 从索引中选择的候选内容项目与先前未向用户呈现的附加内容项目呈现给用户。
