User Profiling and Privacy Protection for a Web Service oriented Semantic Web

In a Web Service-based Semantic Web long term usage of single Services will become unlikely. Therefore, user modeling on Web Service’s site might be imprecise due to a lack of a sufficient amount of user interaction. In our Personal Reader Framework, the user profile is stored centrally and can be used by different Web Services. By combining information about the user from different Web Services, the coverage and precision of such centralized user profile increases. To preserve user’s privacy, access to the user profile is restricted by policies.
