Abstract: Software for an online social service receives a request for a newsfeed from a user. The newsfeed depends at least in part on a memory-cached list of social friends of the user and on a memory-cached list of events associated with each social friend. The software refreshes a memory-cached copy of the list of social friends from a corresponding list in a persistent data store, based upon a determination of a utility associated with the user. And the software refreshes a memory-cached copy of a list of events associated with a social friend from a corresponding list of events in a persistent data store, based upon a determination of a utility associated with the social friend. Then the software causes the newsfeed to be displayed to the user.

Abstract: Software running on servers at a website hosting a news service generates a first profile for a user of the news service. The first profile is based at least in part on implicit relevance feedback from the user on content presented by the news service. The software obtains a second profile for the user from a web-searching service. The software creates a score for a candidate item of content. The score is based on similarity of the candidate item to the first profile and similarity of the candidate item to the second profile. Similarity to the second profile measures at least similarity to a plurality of web-search queries and similarity to any titles of any search results resulting from each of the queries. The software then presents the item of content to the user in a content stream served by the news service, based on the score.

Abstract translation: 在托管新闻服务的网站的服务器上运行的软件为新闻服务的用户生成第一个简档。 第一个配置文件至少部分地基于来自用户对由新闻服务呈现的内容的隐含的相关性反馈。 软件从网页搜索服务获取用户的第二个配置文件。 该软件为候选项目的内容创建分数。 分数基于候选项与第一简档的相似性以及候选项与第二简档的相似度。 与第二简档的相似性至少测量与多个网络搜索查询的相似性，并且与每个查询产生的任何搜索结果的任何标题的相似性。 然后，该软件基于该分数将新闻服务所提供的内容流中的内容的内容呈现给用户。
