Phd Thesis: Provenance and Trust Abstract

The interest in data provenance and trust has been increasing in the last years and the community is putting now a lot of effort in finding a standard model representation. The W3C provenance incubator group is focused on this area, analyzing different provenance models and making mappings between them and the Open Provenance Model (OPM)[1], which is the model they intend to make the standard. We want to develop a provenance system based in OPM and a trust algorithm from that provenance information. Our aim will be a platform that will not store the contents generated by the users, but it will store all the references to them, the opinions from the users, information from social networks, etc. to obtain semantic information from the Web. In this context, being able to predict the trust of a source or being able to track the content we’ve generated is a great choice for any user.
