SERVICE PROVIDING METHOD IN SEMANTIC INFORMATION NETWORK, SEMANTIC INFORMATION NETWORK SYSTEM, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a service providing method in SIONet (semantic information oriented network) which can accommodate so many entities (PC or the like) that desire to participate without making a large capital investment, and can authenticate and charge.

SOLUTION: A service provider generates a base event place EPa based on a base entityα. The entityβof a person who desires a service applies for participation in the base entityα, thereby participating in the event place EPa. The entity of a participant to the event place EPa generates new individual event places EPb to EPe while belonging to the event place EPa. The entityβof the other participant to the event place EPa detects a desired individual event place in the event place EPa. The entityβof the other person who desires to participate participates in the detected individual event place and receives a service from the other entity in the individual event place.
