Trustworthiness of Data on the Web

We aim for an evolution of the Web of data to a Web of trusted data. In our work we develop a trust model for RDF data that is more suitable for the Web of data than the existing coarse-grained approaches that consider trustworthiness on the level of data sources. To enable a trust infrastructure for the Web of data we develop concepts for automatic trust assessment that are based on provenance information and on the opinion of other information consumers. Furthermore, we provide trust-aware data access methods and concepts to implement trust-aware systems.
