Extracting a social graph from contact information across a confined user base

摘要

Embodiments of the present invention relate to extraction of a social graph from contact information across a confined user base. Users are typically subscribed to a service that backs up data from end-user devices to a cloud. The data includes contacts from mobile address books. The service is able to determine relationships of contacts in the cloud to build a social graph or map of these contacts. The social graph can be used to drive individual and group analytics to, for example, increase membership and provide value-added features to its service members.
