Abstract: In one aspect, a method includes identifying a first user viewing a first set of posts at a social networking service, the first set of posts including one or more posts, determining that the level of engagement of the first user at the social networking service is below a predetermined level, generating a second set of posts in response to determining that the level of engagement of the first user at the social networking service is below a predetermined level, the second set of posts including one or more posts not previously seen by the user and providing the second set of posts for display to the user. Other aspects can be embodied in corresponding systems and apparatus, including computer program products.

Abstract: A system comprising a processor and a memory storing instructions that, when executed, cause the system to identify a page on a website, retrieve a stream of posts related to the page, determine whether the page is dynamic, in response to the page being determined to be dynamic, modify the stream of posts related to the page biased toward including more recent posts, generate a user interface element for display of the stream of related content; and provide the user interface element for presentation to the user. The disclosure also includes similar methods and computer program products.

Abstract: In one aspect, a method includes retrieving terms associated with a topic and analyzing the terms based on search results of user queries for content relating to the topic. The method includes selecting one or more terms from the terms based on the analysis. The method includes generating a label from the selected one or more terms and applying the label to a content item relating to the topic. Other aspects can be embodied in corresponding systems and apparatus, including computer program products.

Abstract: Aspects of the subject technology relate to mixing an aggregated content data structure into a content stream. A first plurality of aggregated content data structures is be received, each comprising a group of content items for display in a content stream of a user and being associated with a respective score. A first aggregated content data structure may be selected from among the first plurality of aggregated content data structures based on the scores and predetermined type target percentages associated with the user. The first aggregated content data structure may be mixed into a content stream associated with a user, and the content stream provided for display.

Abstract: In one aspect, a method includes receiving an indication of a request from a user to view a stream associated with the user, generating a request for one or more items visible to the user for display within the stream, the request including a search query identifying search criteria including one or more tokens, the one or more tokens including at least a user token identifying the user, receiving one or more items in response to the request, the one or more items including at least one of the one or more tokens and further being visible to the user and providing the one or more items for display to the user within the stream in response to the request. Other aspects can be embodied in corresponding systems and apparatus, including computer program products.

Abstract: Embodiments include identifying a plurality of communication sessions, each of the plurality of communication sessions having multiple participants. Embodiments may also include applying at least one parameter to each of the communication sessions and determining a non-adjusted value for the at least one parameter for each of the communication sessions. Embodiments may further include determining whether the at least one parameter has been assigned a predetermined weight adjustment. If the at least one parameter has been assigned a weight adjustment, adjusting the value for the at least one parameter based upon the predetermined weight assigned to each of the at least one parameter. Embodiments may include generating a combined value for each of the communication sessions based upon, at least in part, one or more of the non-adjusted value and the adjusted value and ranking each of the communication sessions based upon, at least in part, the combined value.

Abstract: The subject matter of this specification can be implemented in, among other things, a method for providing socially relevant content in a news domain. The methods includes a steop for receiving a request from a user for a news aggregator page related to a news story. The method also includes a step for retrieving social contents items related to the news story. The method also includes a step for providing the news aggregator page for display, wherein the news aggregator page includes multiple links to news content items related to the news story, and the retrieved social content items related to the news story.
