User profile management on service platforms for ubiquitous computing environments

We present a user profile management approach that takes into account basic requirements for its execution on service platforms for ubiquitous computing environments. In particular, our approach provides means for managing and delivering context-dependent user profiles for several applications and decouples the application development from context processing. In addition, it takes into account the re-use and sharing of application-related user data between different applications. Hence, on the one hand, our approach considers the increasing trend to research and develop context-aware and personalized applications for the wireless world. On the other hand it also takes into account the fact that, in general, application and service developers do not agree on common semantics, which complicates the re-use and sharing of user data.
