Abstract

A conference system identifies and manages conferences in terms of the conference host name, conference name and conference partner name. At the setup a conference, a conference host name, conference name and conference partner name are registered, and, in addition, material names and material supplier names of materials used for the conference are registered. The communication conference system stores conference management information in the first, second and third files in the hierarchical structure. The first file stores conferences host names, the second file stores conference names and conference partner names, and the third file stores conference material names and conference material supplier names. A specific conference is identified by a logical AND operation of the conference host name in the first file and the conference name and conference partner name in the second file, and a specific conference material is identified by a logical AND operator of the conference material name and conference material supplier name in the third file.
