Abstract: In one embodiment, a first computing device determines whether one or more conditions are satisfied for not pushing communications to a second computing device associated with a user; and if the one or more conditions are satisfied, then refrains from pushing any communication to the second computing device.

Abstract: In one embodiment, a computer system, in response to a first user's request, creates a location-triggered gift for a second user and for a particular vendor location, determines the second user's location, and transmits information for redeeming the location-triggered gift at the particular vendor location to the second user if the second user is at the particular vendor location.

Abstract: In particular embodiments, a method includes receiving an text query, identifying nodes and edges from a social graph that correspond to character strings from the text query, and then generating recommended queries that include references to the identified nodes and edges.

Abstract: A system and method for measuring user affinity in a social network environment is provided. One or more activities performed by a user associated with a social network environment are monitored. A relationship associated with the one or more activities is identified. An affinity for one or more objects associated with the social network environment is then determined based on the one or more activities and the relationship.

Abstract: A system and method for auction based polling is provided. Parameters related to a poll are received from a first user. Parameters related to a poll are received from a first user. A query is associated with the poll. A priority of the poll is determined based on the parameters. The poll is distributed to one or more second users according to the priority. Results to the poll are gathered. The results are reported to the first user.

Abstract: In one embodiment, a system includes one or more computing systems that implement a social networking environment and are operable to access stored information including a plurality of nodes including a first set of user nodes that each correspond to a respective user and a second set of concept nodes that each correspond to a respective concept. The system may generate a match coefficient for the user and concept, representing the degree of relevance of a particular concept node to a particular user node.

A query is associated with the poll. A priority of the poll is determined based on the parameters. The poll is distributed to one or more second users according to the priority. Results to the poll are gathered. The results are reported to the first user.

Abstract: In one embodiment, a social-networking system accesses a social graph, identifies a first set of concept nodes associated with an application, connected to friends of a user, selects a second set of concept nodes from the first set of concept nodes based on edges connected to the concept nodes, and generates an advertisement for the application, where the advertisement includes information representing the concept nodes in the second set of concept nodes.

Abstract: Methods and systems directed to a social caller ID application that performs a reverse look up on an incoming communication to determine a specific member of a social networking system associated with the incoming communication, and, based on the social relationship between the detected member and the recipient of the communication, display particular information to the recipient. In this manner, a user is provided a caller ID system that leverages information stored remotely on a social network.

Abstract: Systems, methods, and non-transitory computer readable media configured to determine a value of a utility factor associated with a content item corresponding to a link. An optimized utility value relating to an interaction type of an outbound click is determined based on the value of the utility factor. An expected utility score associated with the content item is generated based on the optimized utility value to determine potential presentation of the content item to a user.

Abstract: A method includes classifying a relationship between a first group and each of one or more additional groups based on at least one of a number of communications during a time period and a frequency of the communications. The communications are between one or more members of the first group and one or more members of each of the one or more additional groups. The method includes generating social network data based on the relationship between the first group and each of the one or more additional groups.

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 potions. 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: An application for sharing investment information through social networking websites, such as Facebook®, is disclosed. The application can retrieve investment information from a financial institution via the internet and then select only information that a user wishes to share so sensitive or personal information is removed prior to sharing the investment information. The application can provide access to the investment information through the social networking website by individuals selected by the user. The user can require a fee or other consideration for others prior to providing access to the investment information.

Abstract: A system and method is described for giving gifts via a social network and displaying icons representing assets that have been acquired via the social network. In various embodiments, the assets include real assets, digital assets, and virtual assets. Digital assets that have been acquired via the social network environment may also be displayed. In some embodiments, the assets are received as gifts or in trade from another user of the social network environment.

Abstract: In one embodiment, a method includes sending to a mobile client computing device a first notification through a real-time push service, the first notification including content and being associated with a stateful object; the method also includes, in response to a state change of the stateful object, sending to the mobile client computing device a second notification through the real-time push service, the second notification including an update to the content based on the state change of the stateful object.
