Abstract: Embodiments improve the ability of users of a social networking system to search for information that is likely to be relevant to them by learning and/or applying a search context associated with selector components used to search for objects of the social networking system. The search context is specific to the use of an individual selector and thus need not be as general as the context of an entire page or set of pages in which selectors can be embedded. The social networking system may learn the context of a selector by monitoring user selections from prior search results performed using the selector.

Abstract: In particular embodiments, a social networking system identifies a user viewing video content on a first display device, identifies the video content being viewed on the first display device by the user, and determines a second display device associated with the identified user. The social networking system sends one or more instructions to the determined second display device to display one or more chat messages associated with the identified video content.

Abstract: A social networking system leverages user's social information to evaluate content submitted for inclusion in objects. If the evaluated submission is accepted, the submission is added to the content of an object. Accepted submissions are also used to predict associations between metadata and objects. Metadata is used to predict which objects will match user searches for information. The social networking system also provides a user interface configured to prompt users to submit information to objects. When a user completes a submission to an object, the user is provided with other options for groups of objects to contribute to. The objects offered are chosen to increase the likelihood that the user will choose to provide submissions to one of the provided objects.

Abstract: Equivalent concepts expressed across multiple domains are matched and associated with a metapage generated by a social networking system. User preferences expressed on multiple domains, represented as pages in a social networking system, may be organized by concept and shared with advertisers, third-party developers, and other users of the social networking system using the metapages generated for the concepts. Aggregated social information may be presented to users of the social networking system viewing a page associated with a metapage. Information presented on external websites may be used to link pages across multiple domains with a metapage generated on the social networking system. In one embodiment, the information on other external websites associated with the metapage may be presented as links on the pages associated with the metapage. Feedback from users may be used to include or exclude pages from being associated with a generated metapage.

Abstract: In one embodiment, a method includes accessing a social graph comprising a plurality of nodes and a plurality of edges connecting the nodes, each node corresponding to a user of an online social network, identifying a plurality of clusters in the social graph using graph clustering, providing a treatment to a first set of users based on the clusters, and determining a treatment effect treatment for the users in the first set based on a network exposure to the treatment for each user.

Abstract: Embodiments of the invention improve the ability of a social networking system to determine which types of data—hereinafter referred to as “fields”—are relevant to which types of user pages. Specifically, a social networking system assigns page types to different user pages, and likewise stores information on different types of fields. By analyzing the relationships of different pages and fields, the social networking system determines which types of fields are particularly well-suited for inclusion on different types of pages. Using the learned information about page types and field types, the social networking system can better aid page administrators in specifying data to add to their pages. For example, the social networking system can recommend to administrators the addition of certain types of fields or automatically add the fields. Further, the social networking system can specialize a search for social networking system data to field types.

Abstract: A social networking system provides an instruction that a third-party system may include in a web page or other content. The instruction includes information identifying content presented by the web page or other content specified by the third-party system. The information identifying the content presented by the web page is communicated to the social networking system. Based on the information identifying the content, the social networking system determines a social context for a viewer of the web page. The social context may be selected to optimize for a particular conversion event.

Abstract: To allow third-party websites to leverage social information maintained in a social networking system, a third-party website may include social information for a user in a web page provided by the third-party website. The social information is obtained from the social networking system. The web page provided by the third-party website includes a social context plug-in that causes a user's browser to obtain social information from a social networking system and to incorporate it within the web page. Customization rules are specified by the web page or by the third-party website to determine how the social information is aggregated and presented on the web page. Hence, the customization rules allow an operator of the third-party website to customize the social content displayed with the web page to provide more relevant information to social networking system users interacting with the third-party website.
