Abstract: A method of posting ephemeral posts is disclosed. The method starts with receiving, from a user of a social network, a request to post an ephemeral post, the request including an ephemeral variable associated with a threshold event. The ephemeral post is posted on behalf of the user. Then an occurrence of the threshold event is monitored. When the threshold event has not occurred, the post is allowed to be accessible to at least one viewer other than the user. When the threshold event has occurred, the post is blocked from being accessible by the at least one view other than the user.

Abstract: A social networking system user may associate a graphical element representing the user's emotional reaction with a content item presented by the social networking system. The user is presented with one or more graphical elements maintained by the social networking system and selects a graphical element for associating with the content item. If certain graphical elements are selected, the social networking system prompts the user for compensation or requests compensation from an entity associated with the selected graphical element. The selected graphical element is associated with the content item and a connection, or other information, between the user and the object identifying the selected graphical element is stored by the social networking system. The selected graphical element may be displayed with the content item to the user and to other users connected to the user.

Abstract: In one embodiment, a method includes receiving, from a client system of a first user, a text query inputted by the first user, generating a plurality of structured queries based on the text query, each structured query comprising references to one or more objects associated with the online social network, generating one or more search results corresponding to at least one of the structure queries, and sending, to the client system responsive to receiving the text query, one or more of the structured queries for display, at least one of the structured queries being displayed with a preview of one or more of the search results corresponding to the structured query.

Abstract: In one embodiment, a method includes receiving, from a client system of a first user, a text query inputted by the first user, generating a plurality of structured queries based on the text query, each structured query comprising references to one or more objects associated with the online social network, wherein at least one of the structured queries is a sponsored query comprising a reference to an object associated with an advertiser, and sending, to the client system responsive to receiving the text query, one or more suggested structured queries for display to the first user, wherein at least one of the sent structured queries is a sponsored query.

Abstract: In one embodiment, a method includes receiving, from a client system of a user, an indication of the user accessing a query field at the client device of the user, generating a plurality of structured queries that each comprise references to one or more objects associated with the online social network, calculating a score for each structured query based on one or more user-engagement factors, and sending, to the client system responsive to the indication of the user accessing the query field, one or more suggested structured queries for display to the user, each suggested structured query having a score greater than a threshold score.

Abstract: A social networking system performs account recovery for a user with the help of the user's connections (e.g., friends). The social networking system selects connections of the user based on information indicating likelihood of real-world interactions between the user and the selected connections. Access codes are sent to the selected connections and the user instructed to obtain access codes from the selected connections via a communication that is outside the social networking system, for example, via phone. The user provides the access codes obtained from the selected connections to the social networking system. If the access codes provided by the user match the access codes sent to the selected connections, the user is granted access to the account. Real-world interactions between two users are determined based on sharing of devices between the users or information indicating presence of the users in the same place during same time interval.

Abstract: In one embodiment, a method includes accessing a prior structured query previously selected by a first user of an online social network, where the prior structured query corresponds to a first set of search results and comprises references to one or more objects associated with the online social network, identifying changes to the first set of search results corresponding to the prior structured query, and sending, to a client system of the first user, one or more suggested structured queries for display to the first user, where at least one of the suggested structured queries is a dynamic query comprising at least a portion of the prior structured query and a reference to the identified changes to the first set of search results corresponding to the prior structured query.

Abstract: A social networking system detects spam in comments posted by users of the social networking system. A spam prevention module of the social networking system retrieves content signals associated with a posted comment and analyzes the content signals to determine whether the posted comment contains spam content. The spam prevention module augments the content signal analysis by analyzing social signals of the posted comment. Based on the content signal analysis and the social signal analysis, the spam prevention module determines whether the posted comment is spam and takes remedial actions on detected spam, including blocking the comment and educating the user who posted the comment.

Abstract: In one embodiment, a method includes accessing a social graph that includes a plurality of nodes and edges, receiving from a user a selection of a structured query the user wants to share, where the structured query comprises references to nodes and edges of the social graph, and sending the structured query for display on a page associated with one or more other users.

Abstract: User reports concerning inappropriate content are received by a social networking system and are put into a content report management process that routes the reports into other handling processes based upon the reporting user's identification of the report type. Reports concerning content that is related to the reporting user are routed into a social resolution process that resolves the complaint through self-help and social resolution. Other reports are handled by a content review process that resolves complaints through automated methods as well as manual review by human agents.

Abstract: To determine and quantify the reputations of users within a social network. In an embodiment, a social networking system determines at least one category associated with a first account of a social networking system. The social networking system determines a first reputation score for the first account in the at least one category. The category may represent subject matter in which a user of the first account has an interest. The first reputation score may be based on content posted by the first account. The first reputation score may be adjusted based on an activity and the scores of others.

Abstract: A social networking system generates a newsfeed for a user to view when accessing the social networking system. Candidate stories associated with users of the social networking system are selected and an expected value score for each candidate story is determined. An expected value score is based on the probability of a user performing various types of interactions with a candidate story and a numerical value for each type of interaction. The numerical value for a type of interaction represents a value to the social networking system of the type of interaction. Based on the expected value scores, the candidate stories are ranked and the ranking used to select candidate stories for the newsfeed.
