Abstract: In one embodiment, a method includes sending, from an application server to a first set of client systems, instructions for providing a treatment to a first set of users. The method includes determining an average treatment effect of the treatment for the first set of users based on information about user interactions associated with the treatment and a network exposure to the treatment for each user. Network exposure for a user is a measure of other users associated with the user that have been provided the treatment. The method includes modifying the treatment based on the determined average treatment effect. The method includes sending, to a second set of client systems, instructions for providing the modified treatment to a second set of users. The second set of users is a discrete, non-overlapping set of users with respect to the first set.

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: 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. In one embodiment, a best page may be determined for a user based on information about the user.

Abstract: In particular embodiments a social networking system may receive authorization from a first user of a social-networking system to control at least in part one or more functions of a set-top box (STB) of the first user, determine one or more social actions of one or more second users of the social-networking system, determine one or more instructions for the STB of the first user based at least in part on the social actions, and provide the instructions for the STB of the first user. The social-networking system includes a graph having a plurality of nodes and edges connecting the nodes.

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 using the metapages generated for the concepts. Aggregated social information may be presented to users 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. 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. A best page for a concept embodied in multiple pages may be determined using a hierarchy of rules.

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: In particular embodiments a social networking system captures data associated with video content provided to a first user of a social-networking system, identifies, using the captured data, the video content provided to the first user, and updates a graph of the social-networking system to associate the first user with the identified video content. The graph of the social-networking system has a plurality of nodes and edges connecting the nodes. The nodes of the graph include user nodes that are each associated with a particular user of the social-networking system.

Abstract: In particular embodiments, one or more computer systems of a social-networking system determine identities of one or more users in proximity to a display device and query a social graph of the social-networking system for social content associated with the determined identities. The social graph includes nodes and edges connecting the nodes. The nodes include user nodes that are each associated with a particular user of the social-networking system. The one or more computer systems of the social-networking system identify, using the social content, recommended media content for the one or more users in proximity to the display device and provide a playlist for display on the display device. The playlist includes the recommended media content for the one or more users in proximity to the display device.

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: In particular embodiments, one or more computer systems of a social-networking system determine information associated with a product displayed on a display device and access a database of known products. The one or more computer systems of the social-networking system determine, by comparing the database of known products with the determined information associated with the product, an identity of the product displayed on the display device. The one or more computer systems of the social-networking system provide one or more instructions to display media content related to the identified product.

Abstract: In one embodiment, a computing device receives an indication of a first user action by a first user. The computing device determines a topic of the first user action based on analyzing content associated with the first user action, and determines whether the first user has a preference to exclude posts associated with the topic or a category associated with the topic. If the first user has not indicated any preference to exclude posts associated with the topic or the category, then the computing device identifies a second user action by a second user and related to the topic, and determines whether the first user has indicated a preference to exclude posts associated with the second user. If the first user has not indicated any preference to exclude posts associated with the second user, the first user is provided with access to the second user action.

Abstract: In particular embodiments, one or more computer systems of a social-networking system identify a user viewing video content on a first display device, identify the video content being viewed on the first display device by the user, and determine a second display device associated with the identified user.
