Data Integration and User Modelling: An Approach Based on Topic Maps and Description Logics

In the framework of intelligent information systems design, we present an intelligent data integration and user profile modelling. Our approach uses jointly Topic Maps and Description Logics. Topic Maps are used to represent semantic of distributed data. Using the formalized semantic, the distributed data is merged into one repository. Then, Description Logics are used over this repository to compute implicit semantic relations using logic reasoning such as subsumption. We present then a new user profile management which uses qualifying attributes rather than identifying attributes. Description Logics are used to formalize profiles in order to maintain consistency of right attribution to profiles.
