■Research summary
Web mining, social surveys, and society simulation

 Modelling of relationships of events in real society and in online communities and the interaction between individuals and groups is conducted by web mining, as a social representation, targeting at institutional design of new services and the establishment of hypothesis of operation policies of communities, using social simulation.

The following studies have been conducted so far:

・The effects of opinion distribution cognition has on tweets and attitude change on Twitter (web mining, social survey)
Interruption on news audience on Twitter (web mining, social survey).
・The effects of consolidated information on diversity of culture (social simulation)
・The effects of compensation system in Q&A communities (social simulation) on the activation of communities.
