Abstract

We are developing a framework to acquire knowledge from a peer-to-peer network and to evolve it maintaining local coherence and recoverability of previously acquired data. In this context, we give trust to informations and informa- tion sources in a novel way. Informations acquired from the web is given a truth value, based on previous valuations. Each peer deal with them using a fuzzy extension of RDF semantics, apply extra entailment rules derived from an on- tology, and deal with inconsistencies using belief-revision techniques. The result is a set of consistent and logically closed data that can be visualized and annotated by human users.
