Abstract: Systems and methods to host a social network locally on a user's computing device using social data at the user device. In one embodiment, a method includes maintaining, on a local computing device of a user, social data regarding social relationships of the user in order to support a social network of the user; and hosting, via the local computing device, the social network.

Abstract: Systems and methods to define a social network for a user using data implied by communications of the user with others. In one embodiment, a method includes scanning messages to identify persons addressed in the messages; computing scores of the persons to determine a relevancy of each person; receiving, by a first computing device, a request from a computer program running on a second computing device; in response to the request from the computer program, providing access to friend data for the persons, the computer program to provide services based on the friend data; and sending the friend data to the second computing device.

Abstract: Systems and methods to define a social network for a user using data implied by communications of the user with others. In one embodiment, a method includes scanning a set of messages (e.g., emails to and from a user of a client device) to identify a plurality of primary persons addressed in the messages as a primary recipient and to identify a plurality of secondary persons addressed in the messages as a secondary recipient; mapping the primary persons to a plurality of friends and mapping the secondary persons to a plurality of other persons; and defining a social network model based on the friends and other persons, wherein the model comprises a friends category including the friends and an all category including the friends and other persons.
