| Abstract(in English) | In this paper, we propose a method for observing evolution of web communities. A web community is a set of web pages created by individuals or associations with a common interest on a topic. So far various techniques have been developed to extract web communities by link analysis. We analyze the evolution of web communities by comparing three Japanese web archives periodically crawled in 1999, 2000, and 2001. Several metrics are introduced for measuring the degree of web community evolution, such as growth rate, novelty, and stability. We develop a system for extracting communities and viewing their evolution. This system first extracts whole web communities and their relevance from each archive. Then it provides a web community evolution viewer that allows the user to extract when and how communities emerged and evolved, using the relevance and metrics. Several evolution examples are shown using our system. |
