| Research Abstract |
As a platform of a virtual society experiment, we built a system of social networking, and added the functions of wiki, online questionnaire, vitalization experiments and matching experiments. We obtained some theoretical results, such as, the condition under which vitalization of the SNS occurs. On the other hand, from our experimental results, we confirmed that the specific point system which we constructed is effective for vitalization of SNS, and that long-term relationship can induce cooperative action between people with short-term relationship. Moreover, by survey we investigated the connection between activity in SNS and ordinal human relationship.
