In this paper, we investigate an online forum and construct a social network with the replying relations between comments mapped to the comment authors’ relations. We analyze the network’s feature and apply the statistical physics methods to this complex network research. Then we validate its characteristics of small world networks and successfully find out the opinion leaders in on-line community based on small-world network.
Key words cluster; information communication; on-line community; opinion leader; small-world network
