Abstract. Trust is a necessary concept to realize the Semantic Web. But how can we build a “Web of Trust”? We first argue that a small “Web of Trust ” for each community is very essential to realize a huge “Web of Trust. ” Then, we focus on an academic community as a microcosm of a “Web of Trust ” and show a web mining approach to generate a social network automatically. Each edge is added using the number of retrieved pages by a search engine which includes both persons ’ names. Moreover, each edge is given a label, such as “coauthors” or “members of the same project, ” by applying classification rules to the page content. The relation of persons such as “coauthor” or “same laboratory ” can be described by an RDF format. Finally, using the social network, we calculate authoritativeness of a node as a social trust and an individual trust. 1
