In particular embodiments a social networking system may receive from an external system outside the social-networking system, a request comprising a user identifier associated with a user of the social-networking system, query a social graph for stories generated by one or more connections of the user on the social-networking system, and transmit the stories to the external system. Similarly the social networking system may receive, from an external system outside of the social networking system, a request comprising a user identifier associated with a user of the social networking system, a content identifier, and a action performed by the user on the content identifier, generate a story for the received request, and publish the story to one or more connections of the user on the social networking system.

Sharing Television and Video Programming Through Social Networking

Systems, methods and apparatus for collecting data and presenting media to a user are provided. The systems generally includes a data gathering module associated with an electronic device. The data gathering module communicates gathered data to a management module, which manages at least one user profile based on the gathered data. The management module may select media for presentation to a user based on the user profile, and the selected media may be displayed to the user via a media output device co-located with the user, such as a display of the user's mobile electronic device or a television, computer, billboard or other display co-located with the user. Related methods are also provided.

Methods, systems and apparatus for delivery of media

Systems and methods are presented for detecting users within a range of a media device. A detection region may be defined that is within the range of the media device and smaller than the range. The detection region may be stored. It may be determined whether a user is within the detection region. The media device may be activated and settings associated with the user may be applied when a user is within the detection region. In some embodiments, settings associated with a user may be compared to provided media content when the user is within the detection region. The content may change when the settings conflict with the media content. Reminders may be provided to or directed to a plurality of users within the range of the media device.

Systems and methods for automatically detecting users within detection regions of media devices

A system and method for context based query augmentation. A question is received over a network from a questioning user comprising an identification of a user and at least one question criteria. A first query is formulated so as to search, via the network, for user profile data, social network data, spatial data, temporal data and topical data so as to identify user context data relevant to question criteria. The question is modified using the user context data to create at least one modified question having at least one additional criteria based on the user context data. A second query is formulated so as to search, via the network, for knowledge data, user profile data, social network data, spatial data, temporal data and topical data so as to identify knowledge data relevant to the identified user and the modified question criteria. The knowledge data is transmitted, over the network, to the questioning user.

System and method for context based query augmentation

A computer-implemented method includes receiving, in a computer system, a user query comprising at least a first term, parsing the user query to at least determine whether the user query assigns a field to the first term, the parsing resulting in a parsed query that conforms to a predefined format, performing a search in a metadata repository using the parsed query, the metadata repository embodied in a computer readable medium and including triplets generated based on multiple modes of metadata for video content, the search identifying a set of candidate scenes from the video content, ranking the set of candidate scenes according to a scoring metric into a ranked scene list, and generating an output from the computer system that includes at least part of the ranked scene list, the output generated in response to the user query.

Accessing media data using metadata repository

Content that is significant to a user may be determined. An indication that a user finds content within a document significant may be received. In response to the received indication, the document may be analyzed to identify a set of topics associated with the content of the document. From the set of topics, a subset of topics responsible for the user finding the document significant may be identified. A user profile associated with the user may be updated based on the subset of topics.

Identification of electronic content significant to a user

Instant messages sent by a viewer of a video while the video is perceivable to the viewer may be monitored. An event of interest occurring in the video may be identified based on the monitored instant messages. Metadata that describes the event of interest may be generated and assigned to the video. A request for video content associated with the video may be received from a user. An indexed collection of videos that includes the video may be searched for the requested video content. Based on the search, it may be determined that the video satisfies the user's request. The event of interest occurring in the video may be identified based on the metadata assigned to the video. User perception of a scene from the video that includes the event of interest may be enabled.
