Abstract: In one embodiment, a first computing system receives a request from a second computing system, the request indicating an information item displayed on the second computing system. In response to the request, the first computing system determines whether the information item is associated with any call-to-action provided by any third computing system. If the information item is associated with one or more calls-to-action provided by one or more third computing systems, then the first computing system sends the one or more calls-to-action provided by the one or more third computing systems to the second computing system to be displayed on the second computing system in connection with the information item.

Abstract: In one embodiment communications made using one or more applications are monitored. The communication frequency for the communications with respect to each communication channel and each contact is logged. A social-proximity score for each of the contacts is determined for each contact. The social-proximity score is determined based on social-graph information and the social-graph information comprises a degree-of-separation coefficient for each contact with respect to the user. Each social-proximity score for the one or more contacts is updated based on a frequency coefficient derived from the communication frequency log.

Abstract: To provide more contextually and temporally relevant information to its users, a social networking system may surface relevant information about a target user with whom an recipient user is likely to interact. The social networking system predicts whether the recipient user is likely to be in contact with a target user, either currently or in the near future. If contact is predicted, the system determines information about the target user that that the recipient user may find of interest for their interaction. To determine what information may be of interest, the system determines a relevance score for information items about that target user. The system can then use the relevance scores to decide whether and which information items to surface to the recipient user, e.g., in the form of notifications.

Abstract: A computer-implemented user notification method includes displaying, in a status area near a perimeter of a graphical interface, a notification of a recent alert event for a mobile device, receiving a user selection in the status area, and in response to the receipt of the user selection, displaying, in a central zone of the graphical interface, detail regarding a plurality of recent messaging events for the mobile device.

Abstract: A social networking system provides relevant third-party content objects to users by matching user location, interests, and other social information with the content, location, and timing associated with the content objects. Content objects are provided based on relevance scores specific to a user. Relevance scores may be calculated based on the user's previous interactions with content object notifications, or based on interests that are common between the user and his or her connections in the social network. Context search is also provided for a user, wherein a list of search of results is ranked according to the relevance score of content object associated with the search results. Notifications may also be priced and distributed to users based on their relevance. In this way, the system can provide notifications that are relevant to user's interests and current circumstances, increasing the likelihood that they will find content objects of interest.

Abstract: In one embodiment, a user of a social networking system requests to look up an address book maintained by the social networking system. The social networking system improves the look up search results by ranking one or more contacts in the address book based on social graph, social relationship and communication history information.

Abstract: In one embodiment, accessing a set of characters of a search query currently entered into a text entry box; compiling a first set of search results based on the set of characters currently entered into the text entry box, wherein the compiling is re-executed responsive to changes to the set of characters entered into the text entry box; associating an image with each search result from the first set of search results; and presenting the first set of search results as a first set of images adjacent to the text entry box.

Abstract: In one embodiment, a computing device selects a number of location updates from users which corresponds to a place. Each location update includes data indicating a geographic location that a user was at, and a time corresponding to when the user was at the geographic location. The computing device selects a first subset of the location updates which have geographic locations within a particular geographic area. For each location update in the first subset, the computing device determines a corresponding user and time. The computing device selects a second subset of location updates, each location update in the second subset corresponding to a user from the first subset, and a time within a threshold time of the time of the location update in the first subset. The computing device generates a probability map based on a distribution of geographic locations corresponding to the location updates in the second subset.

Abstract: In one embodiment, a social networking system automatically tags one or more users to an image file by creating a list of potential matches, and selecting a subset of potential matches based on location, asking a first user to confirm the subset of potential matches, and tagging one or more matched users to the image file.

Abstract: In one embodiment, a method includes receiving a request at a wireless access point from a client system to access a network through the wireless access point. The wireless access point sends an identifier associated with the client system to a social-networking system, the social-networking system including user profiles arranged in one or more social graphs. The social graphs store relationships between the user profiles. The method further includes receiving at the wireless access point from the social-networking system an authorization determination. The authorization determination is based upon a first user profile of the plurality of user profiles. The first user profile includes the identifier associated with the client system. The method further includes providing the client system with access to the network through the wireless access point in accordance with the authorization determination.

Abstract: In particular embodiments, two or more users are provided with personalized experiences while using a shared mobile computing device. A login interface is presented for a plurality of users of the shared mobile computing device. When an indication of a login action by a first user of the plurality of users is detected, access to restricted information associated with any other user of the plurality of users is disabled. Cached information associated with the first user is retrieved from a local data store. A personalized user interface is then presented, based on the cached information. Updates to information and/or content may be cached and/or stored remotely. When an indication of a logout action by a first user of the plurality of users is detected, particular information and/or content is flushed from the local data store.

The set of contact information includes one or more instances of contact information in one or more categories of contact information. The computing device automatically selects, in each of the categories of contact information, one of the instances of contact information from the sets of contact information as a default for the category of contact information for a second user of the social-networking system.

Abstract: A social networking system allows a first user to provide contact information for a second user via a synchronization or upload event from a computing device. The second user is prompted as to whether he or she wishes to share the received contact information on his public profile. If he or she responds affirmatively, the updated contact information is stored in association with the second user's profile on the social networking system. If the user responds negatively, the contact information is stored on the social networking system in association with the uploading user.
