Abstract: Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium for providing content. A method includes: identifying a plurality of segments of viewers wherein each segment is associated with an entity; identifying pairs of segments for comparison; responsive to a request for content, identifying a content item for presentation on a user device; identifying a first pair of segments that are associated with the content item; determining, for each segment of the first segment pair, a response metric associated with responses to the content item, the responses attributable to entities in a given segment; and providing the content item responsive to the request including providing results associated with the response metric for both segments of the first pair of segments for presentation along with the content item.

Abstract: A method performed by one or more processing devices includes receiving information specifying one or more attributes of a story; identifying, from a social graph, items of data with attributes matching at least one of the one or more attributes of the story, and connections to an item of data representing a user for whom the story is generated; identifying content items associated with the identified items of data; generating, based on the identified content items, data for a graphical user interface that when rendered by a device used by the user, includes: a visual representation of the story.

Abstract: Techniques for providing electronic content may include: identifying members of a social network that have a characteristic in common; determining a first proportion of the social network that the members compose; determining that a first member of the social network has the characteristic; identifying first content from the members that have the characteristic in common; and outputting second content from the social network to the first member. At least some of the first content may be included in the second content, and the at least some of the first content may represent a second proportion of the second content, where the second proportion is based on the first proportion.
