Abstract
Trust on Web is one of most important issues to realize Semantic Web, because Semantic Web enables intelligent processing and automatic processing on all Web resources, even though they varies in trust. In this article, I overview technologies for realizing trust on Web. First I introduce trust from socio-psychological view. Then I classify the current trust technologies according to the following aspects: types of information that trust is based on, its coverage, its acquisition method, and its computation model. Finally, I briefly explain named graph as metadata format that trust may be based on.
