Abstract: The present invention facilitates determining a shared context between users of a computer system and dynamically generating a display of the shared context of one user from the perspective of the other user. The data from which a shared context between users may be determined includes data indicating that the users have something in common. Among other data, data indicating that the users have something in common may include data indicating a relationship, past or present, or direct or indirect, between the users. Alternatively, or in addition, data indicating that the users have something in common may include associations with the same individuals, communities, activities, or other special interests, whether those associations are past or present, and explicit or implicit.

Abstract: Systems and methods for automatically recommending a personal network. The systems can include a review module programmed to review communication information. The systems can also include a recommend module in data communication with the review module, the recommend module being programmed to identify one or more contacts from the communication information to be included in a personal network. The recommend module can use a significance function to weight the communication information and rank the contacts identified in the communication information.
