Distributed Creation and Revision of Domain Knowledge Based on Rich Semantic Web Clients

Giovanni Tummarello, Christian Morbidoni, Michele Nucci

In this paper we present a novel kind of personal application: Rich Personal Semantic Web Clients. The idea is to enable to user to create and experience the Semantic Web as a collection of local databases which interoperate in semantic P2P "topic" channels by exchanging patches of RDF information. Once sufficient information has been collected locally, rich, fast browsing of the "Semantic Web" becomes possible without generating external traffic or computational load. Also user defined rules, trust metrics, filtering, can be freely applied. "Semantic Web" data can be furthermore integrated with personal local semantic data such as local sources or Desktop information. A prototype of such client, DBin, is presented and then we describe issues such as user interfaces and the social aggregation model induced by this novel application model.
