Abstract

In the paper, we first present an approach to extract social networks from message boards on the Internet. Then we measure structural features of 3,000 social networks extracted from 3,000 message boards from 15 categories in Yahoo!Japan Message Boards to prove the relationships between the features and the categories. Using hierarchical cluster analysis, we show three types of social networks.
