Abstract: A viewing user is provided with social advertisements when accessing content associated with a social networking system. A social advertisement can include a candidate advertisement and an associated social story. Candidate advertisements are advertisements provided by one or more advertisers, where the advertisements each specify a relationship between their advertising content and one or more social networking objects. To identify social stories associated with the candidate advertisements, the social networking system identifies other users associated with the viewing user who has interacted with social networking objects that are related to candidate advertisements. Additionally, the social networking system identifies the one or more interactions between the other users and the one or more objects as a social story.

Abstract: A social networking system provides access to personas comprising information, for example, web pages describing users or entities. The information may be suggested by the social networking system or requested by the user, for example, via search. The social networking system authenticates the personas so that only authentic personas are suggested to users or returned when a user is searching for information. The authenticity of a persona is determined based on the connections and/or likes coming from other personas, user accounts, or other entities represented within the social networking system that have been previously authenticated. The authenticity of the person is also determined based on external links to the persona, for example, external websites referring to the persona or the rate at which external systems such as search engines direct web traffic to the persona.

The frame header may include a message-enabled flag, a message-count flag, at least one message-size flag corresponding to each of the accompanying messages, and message-data corresponding to the contents of the accompanying message(s). The message-count flag indicates a number of accompanying messages being included in the frame header, and each message-size flag indicates the size of a corresponding accompanying message.

Abstract: Systems and methods for identifying, in a network environment in which users watch videos that are downloaded or streamed over a network, a video in which a user is likely to be interested based on session context. For example, a server or other computing system identifies prior session contexts in which prior users watched videos and session progress data for prior sessions in which these prior users watched the videos. The server or other computing system determines a session context of a user for whom a video is to be recommended. For this user, the server or other computing system generates a recommendation identifying one or more videos in which the user is likely to be interested, where the user has not previously watched the recommended videos. The recommendation is generated based on the prior session contexts, the session progress data, and the session context of the user.
