We present the User Modeling Service, a service to model a user across various applications. Our service is not restricted to a specific domain and can hence be integrated into arbitrary Web applications. To enable the reuse of user profile data from different applications, we adhere to wellknown Semantic Web technologies. In addition, we developed an easy-to-use Web interface, which allows users to inspect, control, and modify their data. This Web interface is also used to create access policies, which allow users to specify on a fine-grained level which application or Web Service is allowed to access which part of the user profile.enText/Conference Paper
