Abstract: A social graph may be modeled as a collection of claims. Each claim is associated with an author, an audience, and an assertion about a fact. Probabilistic information may be collected from various sources for a claim, enabling a social networking system to evaluate a truthfulness of the assertion made in the claim. User-declared profile information may be evaluated as claims. A user, entity, or application may make claims about any assertions made in the social networking system. Reputation scores may be determined for users based on evaluations of their historical assertions. Claims may be evaluated for truthfulness using a probabilistic prediction model using heuristics analysis, regression analysis, and machine learning methods. A claims-based profile of users may be provided to viewers based on the contexts in which the claims were made. Viewers may view claims made about users, such as the users' biographical information, contact information, expertise, and interests.

Abstract: A social networking system includes a question and answer system that displays to a viewing user questions and answers provides by other users of the social networking system. The question and answer system may display answers to a particular question in a way that visually indicates both the global answer set and a subset of the global answer set, such as the viewing user's friends. The social networking system may also display to a viewing user news stories about another user asking or answering a question, where the format of the displayed new stories is based on an affinity that the viewing user has for the user who provided the question or answer mentioned in the news story. The displayed questions and/or answers may be associated with an object in the social networking system, where the user interface provides additional information about those objects.

Abstract: A social networking system facilitates a user's creation of a group of other users from among the user's connections in the user's social network. The created groups may be used, for example, to publish information to certain user-defined groups or to define privacy settings or other access rights to the user's content according to such user-defined groups. When a user adds connections to a group, the social networking system determines a characteristic associated with the group and identifies whether the characteristic is specified in user profiles of the added connections. If the user profiles lack the characteristic, the social networking system suggests to the connections to update their user profiles with the characteristic.
