The Study of Human Behavior Dynamics Based on Blogosphere

Blog and microblog have become one of the most popular applications which individuals could be the message source. Therefore, interactivities between individuals have been largely enhanced in today´s world. In terms of message delivery and human behavior, understanding the mechanism behind is of significance. Though human dynamics has become a popular subject, most of relevant studies so far used the Poisson process to approximately describe the human behavior. However, extensive evidences like email exchange, online game, and mobile communication showed a non-Poisson statistics with heavy tail in those applications. Meanwhile the study in human dynamics is still rare to some extent. Thus in this paper, the authors provided empirical evidences to support such a non-Poisson statistics being existed in the web2.0 applications blog and microblog, also showing the difference between these two applications. The fact that both human behavior in blog and microblog follow a heavy tailed distribution with α≈1.3 and α≈2 will be revealed. At last, the study of human behavior related to social network can also be enriched.
