Finding Social Network for Trust Calculation

Trust is a necessary concept to realize the Semantic Web. But how can we build “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 one of small “Web of Trust” and show a Web mining approach to automatically generate a social network. Each edge is added using the number of retrieved pages by a search engine which include both persons’ names. Moreover, each edge has a label such as “co-authors” and “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 a RDF format. Finally, using the social network, we calculate authoritativeness of a node as a social trust and an individual trust.
