    Abstract: In one embodiment, one or more computing systems receive a request for a location prediction for a user from a service. The computing systems access one or more real-time location signals and one or more aggregated location signals. The aggregated location signals may comprise one or more previous location signals. The computing systems may then generate one or more location predictions from the one or more real-time location signals and the one or more aggregated location signals, and calculate a single location prediction for the user from the one or more location predictions. The computing systems may then send, in response to the request, the single location prediction for the user to the requesting service.

    Abstract: Techniques to manage client location detection are described. In one embodiment an apparatus may comprise a location-based services support component and a client management component. The location-based services support component may be operative to determine that a network service is scheduled for a location update from a mobile device, determine a location accuracy based on the network service, and update the network service with a received location of the mobile device. The client management component may be operative to transmit a location request to the mobile device, the location request specifying the location accuracy determined based on the network service and receive a response to the location request from the mobile device, the response comprising the location of the mobile device conforming to the specified location accuracy. Other embodiments are described and claimed.

    Abstract: In one embodiment, a mobile client system of a first user may determine a first location of the mobile client system, where the first user corresponds to a first node of a social graph of the online social network, the social graph comprises a plurality of nodes and a plurality of edges connecting the nodes, and each of the edges between two of the nodes represents a single degree of separation between them. The mobile client system may send an indication of the first location and one or more and one or more notification preferences to a computing system associated with the online social network. The mobile client system may receive a notification referencing one or more second users of the online social network, where each second user is associated with a mobile client system having a second location within a threshold distance of the first location.

    Abstract: Particular embodiments of a social-networking system maintain one or more data stores storing a social graph comprising user nodes, concept nodes, and edges connecting the nodes. Particular embodiments may determine a confidence score with respect to a user node and a concept node, wherein the confidence score is based at least in part on affinity scores associated with the edges along a sequence of nodes between the user node and the concept node in the social graph. The confidence score may be based on an overall probability that a random walk starting at the user node will end at the concept node. This overall probability may be determined by calculating, for each edge in the random walk, the probability of taking that edge during the random walk, based on the affinity score associated with that edge.
