Abstract: A system is provided for selectively presenting a portion of an event to a user. The system includes a first device, a second device, and a network allowing communication between the first and the second device. An application at the first device displays a plurality of sub-events that characterize an event; receives an input from a user whereby the user selects a sub-event from the plurality of sub-events; sends a request to a second device, the request comprising information associated with the selected sub-event; receives media data from the second device whereby the media data represents the selected sub-event; and presents the received media data. An application at the second device receives the request from the first device, selects the media data that represents the selected sub-event from a database using the information associated with the selected sub-event, and sends the selected media data to the first device.

Abstract: Social networking system users may create events where a group of other users invited to the event meet at a specified time and location. While an inviting user initially specifies the group of users to invite to the event, the social networking system suggests additional users to invite to the event. The social networking system suggests additional users based on a prediction that the users would attend the event if invited. Various factors may be used to make the prediction, such as an affinity between the inviting user and the other users, the availability of the other users at the time of the event and/or the proximity of the other users to the location of the event. Invitations to the suggested additional users may be automatically sent or sent to a set of the additional users selected by the inviting user.

Abstract: A social networking system allows a user to insert media information into content posted by the user, where the media information identifies a media item that the user is consuming while composing the posted content. When a user of a social networking system composes content via a composer interface, the user may select an option on the composer interface to record audio using a microphone on the user's device. A media item is identified from the recorded audio and information about the identified media item is added to the user's posted content. The system may also update information about the identified media item and the composing user.

Abstract: A social networking system obtains specific structured data about a user via a composer interface having textual content with incomplete portions and input fields corresponding to the incomplete portions. The input fields map to data fields in the user's profile and are selected based on the social networking system's need for the information associated with the data fields.

Abstract: A social networking system allows a user to create an event in the social networking system while viewing a web page from a third-party website from a domain different than the social networking system. A widget or other social plug-in is included in the web page, and user interaction with the widget communicates information from the web page to the social networking system. An event object is created in the social networking system from the information from the web page. The social networking system may perform various actions to increase user interaction with the created event object, such as identifying additional users to invite the event or identifying users attending the event to other users.

Abstract: An online system, such as a social networking system, may determine user trends and identify actions to be taken by users that may help optimize revenue for an advertiser. A social networking system may generate offers for an advertiser based on the user trends, user characteristics, and claims about users where the offers include actions determined by the social networking system that users may take to help optimize revenue for advertiser. Venues may also sell ad space, ad inventory, and real-time customer data to advertisers through a social networking system.

Abstract: A social networking system identifies an event based on a thread including messages from users of the social networking system and communicates invitations to the event to one or more invited users. The social networking system receives a response to an invitation from a responding user and identifies a group of users invited to the event that have not responded to the invitation. From the users invited to the event that have not responded to the invitation, a subset of users having a threshold affinity to the responding user are selected. The social networking system notifies the subset of users of the responding user's response to the invitation and may also provide the subset of users with a suggestion for attending the event.

Abstract: A composer interface provided by a social networking system allows a user to provide input, such as text data, to the social networking system. The composer interface allows the user to identify an action and/or an object related to the input. An action is structured data describing a relationship between objects defined by the social networking system. Based on the action identified as related to the input, the social networking system stores an association between the received input and the identified action.

Abstract: A map interface presents a geographic map with markers identifying geographic locations associated with content items. When the geographic distance between two or more content items is less than a threshold distance, multiple content items are grouped to create an aggregated content item. Based on the geographic locations associated with the grouped content items, a geographic location is associated with the aggregated content item. A single marker identifies the geographic location for the aggregated content item on the geographic map. When a user viewing the map interface accesses the single marker, content selected from the content items combined to generated the aggregated content item is presented as well as the geographic location associated with the aggregated content item.

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: A social networking system presents questions to a user on an interface associated with the social networking system to elicit information about the user that is missing from the user's profile or is otherwise outdated. The questions are selected based on a number of factors, such as the need for or value of the information item, probability of a response, or cost of collecting the information item. In presenting the selected question, the social networking system prompts a user for information about the user in a an interface associated with a page from the social networking system, an application external to the social networking system, or using a push notification or prompt. The questions may be formatted in various ways, such as an explicit question, confirmation, a selection of responses, or social context to encourage the user to respond to the question.

Abstract: A map interface presents a geographic map with markers identifying geographic locations associated with content items. When the geographic distance between two or more content items is less than a threshold distance, multiple content items are grouped to create an aggregated content item. Based on the geographic locations associated with the grouped content items, a geographic location is associated with the aggregated content item. A single marker identifies the geographic location for the aggregated content item on the geographic map. When a user viewing the map interface accesses the single marker, content selected from the content items combined to generated the aggregated content item is presented as well as the geographic location associated with the aggregated content item.
