Abstract: In one embodiment, a method includes accessing a social graph of a social-networking system, and determining, from the social graph, that a user “likes” a first page associated with a particular version of a media content. The social graph includes a plurality of 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 method further includes determining that one or more other versions of the media content exist, determining that a main page is associated with the particular version and the one or more other versions of the media content, and aggregating the user's “like” of the first page to the main page. Each of the one or more other versions of the media content has one or more associated pages.

Abstract: A computer-implemented augmented reality method includes receiving one or more indications, entered on a mobile computing device by a user of the mobile computing device, of a distance range for determining items to display with an augmented reality application, the distance range representing geographic distance from a base point where the mobile computing device is located. The method also includes selecting, from items in a computer database, one or more items that are located within the distance range from the mobile computing device entered by the user, and providing data for representing labels for the selected one or more items on a visual display of the mobile computing device, the labels corresponding to the selected items, and the items corresponding to geographical features that are within the distance range as measure from the mobile computing device.

Abstract: In one embodiment, a method includes accessing geolocation data indicating a first geolocation of a mobile computing device of a user of a social-networking system.

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: A client device receives advertisement content associated with an entity having a physical location and one or more instructions that, when executed, present information identifying the physical location. The client device displays an ad unit including the received advertisement content and a link associated with the instructions to present the information identifying the physical location. If a user selects the link, the client device presents information identifying the physical location, such as a map, within the ad unit. Additional instruction may be included in the advertisement that, when executed by the client device, execute an application installed on the client device to provide directions to the physical location.

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.
