Research Abstract

The technique that can estimate size of the community of Internet forums as a technology to support safe communication in the Internet is proposed. The communityhere is defined as a group of person contributing it in the future. The proposedestimates the number of contributors who have not posted yet. This is not easy for eventhe administrator of the server. Using the invariant emergent property of the groupthe number of the remaining member is able to be estimated by the number of themembers who have posted so far. I showed that the proposed method can provide amore reasonable community than a community consists of only posted members by theexperiments using server load data of the internet forums and TV viewing rates.
