ABSTRACT:
A system is disclosed by which the load when a user tries to selectively communicate through a network with a person having information useful to the user from among a large number of persons can be distributed suitably on the network without the necessity for a large-scale network server. The user transmits profile information from a user apparatus to a plurality of different apparatus of different users. Each different apparatus uses the profile information and profile information of the user of the different apparatus to calculate correlativity between the users and sends back a result of the calculation. The user apparatus selects, from the results of the correlativity calculation from the different apparatus, an apparatus of a communication opposite party who exhibits a comparatively high correlativity, and issues a notification of or receives utilization information to or from the selected apparatus by communication.
