Particular embodiments may receive one or more data items associated with a first user of a social-networking system. The one or more data items being related to an entity. One or more data stores may store a social graph of the social-networking system. The social graph may comprise a plurality of nodes and plurality of edges between nodes. The nodes may comprise user nodes corresponding to users of the social-networking system and concept nodes corresponding to concepts. Particular embodiments may identify one or more nodes of the social graph that likely match the entity and associate at least one of the data items to at least one of the identified nodes.

Soft matching user identifiers

In one embodiment, a method includes receiving a message associated with a user at an information exchange system. At least one correspondent associated with the user may be determined, based on the message. A social connection between the user and the at least one correspondent may be assessed with respect to a social-networking system. The information exchange system may provide an interface for display to the user, the interface comprising information associated with the message. If the social connection is confirmed, the interface may include social-networking information associated with the at least one correspondent. Otherwise, the interface may provide functionality to create a social connection between the user and the at least one correspondent with respect to the social-networking system.

Integrating social-networking information

Techniques to increase engagement with a social networking system. In one embodiment, activities are prioritized based on relatedness to a user. References associated with at least a portion of the prioritized activities are created. The references are categorized into a plurality of types. The reference types may include notifications, friend identifications, and top stories. The references are embedded in digest communications for the user. Descriptive information about the activities are omitted from the digest communications. Digest communications for the user are provided during a time period when the user is not engaged with the social networking system. Notifications for a user are ceased when a level of engagement of the user with the social networking system is less than a threshold value.

Methods and systems for optimizing engagement with a social network

In one embodiment, a social networking system transmits a client proxy application to a client device in order to export data from a third-party site that has instituted IP address blocking or rate limiting. In particular embodiments, the proxy application multiplexes a plurality of web responses from the third-party server over a single socket communication with a proxy server. In particular embodiments, the proxy application obtains data from the third-party service and relays it via the proxy server to the social networking system.

Secure proxied data retrieval from third-party services

Techniques to increase engagement with a social networking system. In one embodiment, an engagement level of a user with a social networking system is monitored. A low engagement user type associated with the user is identified from a plurality of low engagement user types. It is determined whether the engagement level of the user is less than a threshold. If so, a communication is provided for the user based on the low engagement user type associated with the user. The communication may be a notification or a digest communication.

Methods and systems for increasing engagement of low engagement users in a social network

Techniques to optimize messages sent to a user of a social networking system. In one embodiment, information about the user may be collected by the social networking system. The information may be applied to train a model for determining likelihood of a desired action by the user in response to candidate messages that may be provided for the user. The social networking system may provide to the user a message from the candidate messages with a selected likelihood of causing the desired action.

Methods and systems for optimizing messages to users of a social network

Optimizing messages to users of a social network using a prediction model that determines likelihood of user performing desired activity

Optimizing messages to users of a social network using a message that includes a user's performance of a desired activity associated with a link included in the message

Method or system for allowing a social networking system to retain users of a social networking system by identifying low-activity users who are likely to become inactive/dormant users and prompting users to initiate interactions with the low-activity users. The low-activity users are identified by monitoring activities and interactions of the users via the social networking system. If the pattern of activities and interactions satisfy one or more criteria, a computer device for providing the social networking system initiates an intervention scheme where users are induced to initiate interactions with the low-activity users. In response to the interactions, the low-activity users are likely to resume interactions via the social networking system.
