Using context- and content-based trust policies on the semantic web

The current discussion about a future Semantic Web trust architecture is focused on reputational trust mechanisms based on explicit trust ratings. What is often overlooked is the fact that, besides of ratings, huge parts of the application-specific data published on the Semantic Web are also trust relevant and therefore can be used for flexible, fine-grained trust evaluations. In this poster we propose the usage of context- and content-based trust mechanisms and outline a trust architecture which allows the formulation of subjective and task-specific trust policies as a combination of reputation-, context- and content-based trust mechanisms.
