Revealing connections for persons in a social graph

摘要

An online system utilizing a social graph allows users to establish an account with the system and establish connections to nodes in the system. The social graph uses system-provided nodes that are created and maintained by the system, so that users cannot edit the system-provided nodes. The system aggregates and analyzes the social graph to present information in ways useful to its users. For example, the system reveals connections between persons in the system, with a corresponding strength of each connection.
