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

Abstract

In a Web Service-based Semantic Web long term usage of single Services becomes uncommon. Therefore, user modeling on Web Service’s site will be imprecise due to the lack of a sufficient amount of user interaction. In our Personal Reader Framework user model is stored in a central place that can be accessed from different Web Services. By combining informations from different Web Services confidence of the user profile increases. To preserve user’s privacy, access to the user profile is restricted by policies. To enhance usability Personal Reader Framework, additionally, offers a single access point to the Semantic Web assisting the user in terms of discovering, configuring and invoking Web Services.
