The core idea of this paper is to infer from proximity people’s common interests. Example: if two people regularly exercise in the same fitness centre, Social Net detects this pattern and assume they share common interests. In addition a set of automated actions is carried out by the agent. For example, Social Net searches in the contact list of the persons “in proximity” and if a common friend is found then this person is suggested to introduce the two friends in common.
