Community web and social networks

Yutaka Matsuo and Hideaki Takeda will discuss their work on supporting communitys on the Web.

The Web is not used just for information publishing but also communication. We model web as an infrastructure to support human activities on information and communication, i.e., community web. In order to explore this concept, we are investigating various possibilities of web from extension of weblog to web mining.

We introduce social network extraction from the Web and its application for a conference support system, called Polyphonet. Several social networks are extracted and analyzed. Also we developed two extensions of weblogs to enhance communication among users. One is Semblog that extends weblog to include interaction among users with FOAF. The other is ActionLog that extends weblog to include the real world context.
