Blog コミュニティの抽出と分析 Detecting and Analyzing Community in BLOGs

Recently there are many blog hosting services in Japan and users are getting larger and larger. The Blog users seem to make new communities on the Internet. In this paper, we extract and analyze Blog communities based on the link structure of Blog. Blog networks can be constructed as follows: a Blog (whole entries of one Blog) is considered as a node, and a link between two Blogs is considered as an edge. We try two experiments to two areas: scoring Blog pages by PageRank and clustering Blog communities by betweenness clustering for the Blog networks on "baseball" and "Winny."
