Accessing data in the semantic web: An intelligent data integration and navigation approaches

We present an original navigation approach to explore data in the framework of the semantic web. Before navigation, data are represented and integrated by jointly using Topic Maps and description logics. Our navigation approach improves the traditional web navigation with two specificities. First, the navigation paths are semantic instead of structural links. Second, it is a subject-centric instead nothing-centric. These two facilities increase the efficiency of information retrieval in the Web. They are implemented in an adaptive interface, which browses, gradually, data as a concept map with rest to user navigation.
