Abstract: In one embodiment, a geo-social networking system determines a user's current location, calculates a novelty score for the location representing the user's degree of familiarity, and surfaces content within a geographic and temporal radius based on the novelty score for display to the user.

Abstract: In particular embodiments, one or more computer systems of a social-networking system determine available media content from one or more content sources and query a social graph of a social-networking system for social content associated with a user of the social-networking system. 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 determine, using the social content and the available media content, a plurality of social coefficients for the user, determine, based on the determined social coefficients, recommended media content for the user, and provide the recommended media content for display in a programming guide on a display device.

Abstract: In one embodiment, a computer system determines a wireless transmit cost for each of one or more outgoing messages for a first user, and transmits to the first user's mobile device at least one of the one or more outgoing messages based on the mobile device's power state and respective wireless transmit costs of the one or more outgoing messages.

Abstract: Techniques for prompting communication among members of a social network are described. A social server may include an interaction detection component configured to detect a user interaction of a first user with an information unit. An information component of the social server may be configured to store an association between the first user and the information unit. A correlation component of the social server may be configured to correlate the first user with one or more other users based upon one or more stored associations. A messaging server may include a display component and a messaging component. The display component may be configured to provide a prompt to the first user suggesting that the first user initiate a communication with the one or more other users, the prompt based at least in part on the correlation. The messaging component may be configured to initiate a communication with the one or more other users in response to a selection of the prompt by the first user.

Abstract: In particular embodiments, the newsfeed is rendered to a particular user using the locally stored copy of the resource, instead of pulling it back from the server-side. Thus, a user may see his or her content even before it is completely uploaded to the social networking system. In particular embodiments, the user may interact with the content, for example, by adding comments, captions, “likes”, etc. to the content even before it has been completely uploaded to the social networking system. In this manner, the user is provided an increased feeling of responsiveness that is independent of the current wireless link condition.

Abstract: In one embodiment, one or more computing devices receive, from one or more mobile devices respectively associated with one or more users, one or more sets of data, wherein each set of data comprises: a user identifier indicating to which user the set of data corresponds; a location where the corresponding user was at; and a time when the corresponding user was at the location. The computing devices store the one or more sets of data; and extract one or more statistics from the one or more sets of data that represent behavioral pattern of at least one of the one or more users.

Abstract: In one embodiment, a method includes generating a waveform fingerprint based on captured ambient audio data; calculating a location of the computing system; sending the generated waveform fingerprint and the location to a server; and receiving instructions from the server to adjust one or more device settings of an output device of the computing system. The instructions being based at least in part on identifying one or more audio fingerprints that match the generated waveform fingerprint and correlating one or more of the identified audio fingerprints to a physical environment of the computing system. The method also includes adjusting one or more of the device settings of the output device of the computing system in accordance with the received instructions.

Abstract: In particular embodiments, one or more computer-readable non-transitory storage media embody software that is operable when executed to receive an audio waveform fingerprint and a client-determined location from a client device. The received audio waveform fingerprint may be compared to a database of stored audio waveform fingerprints, each stored audio waveform fingerprint associated with an object in an object database. One or more matching audio waveform fingerprints may be found from a comparison set of audio waveform fingerprints obtained from the audio waveform fingerprint database. Location information associated with a location of the client device may be determined, and the location information may be sent to the client device. The client device may be operable to update the client-determined location based at least in part on the location information.

Abstract: In one embodiment, a geo-social networking system automatically tags one or more social contacts of a first user to a photo of the first user by ranking the social contacts based on spatial and temporal proximity to the first user, and in response to the first user's selection of one or more top ranked social contacts, associating the selected social contacts to the photo.

Abstract: In one embodiment, a mobile device automatically captures image frames by acquiring a real-time video sequence, selecting one or more frames from the real-time video sequence based on social network information and identity recognition, and storing the selected one or more frames in a local storage of the mobile device.

Abstract: Particular embodiments determine that a textual term is not associated with a known meaning. The textual term may be related to one or more users of the social-networking system. A determination is made as to whether the textual term should be added to a glossary. If so, then the textual term is added to the glossary. Information related to one or more textual terms in the glossary is provided to enhance auto-correction, provide predictive text input suggestions, or augment social graph data. Particular embodiments discover new textual terms by mining information, wherein the information was received from one or more users of the social-networking system, was generated for one or more users of the social-networking system, is marked as being associated with one or more users of the social-networking system, or includes an identifier for each of one or more users of the social-networking system.

Abstract: Client devices periodically capture ambient audio waveforms and modify their own device configuration based on the captured audio waveform. In particular embodiments, client devices generate waveform fingerprints and upload the fingerprints to a server for analysis. The server compares the waveform fingerprints to a database of stored waveform fingerprints, and upon finding a match, pushes content or other information to the client device. The fingerprints in the database may be uploaded by other users, and compared to the received client waveform fingerprint based on common location or other social factors. Thus a client's location may be enhanced if the location of users whose fingerprints match the client's is known, and, based upon this enhanced location, the server may transmit an instruction to the device to modify its device configuration.

Abstract: In one embodiment, a first computing device determines a priority of a communication to be pushed to a second computing device. The priority of the communication is based on a relevance score of the communication with respect to a user of the second computing device. The first computing device sends the communication via a push notification to the second computing device if the priority exceeds a predetermined threshold. The push notification itself comprises the priority of the communication, and the push notification is received by a secondary processor of the second computing device.
