Managing and delivering context-dependent user preferences in ubiquitous computing environments

We present a user profile management component for ubiquitous computing environments that provides management, inquiry and delivery of context-dependent user preferences. In particular, our approach takes into account that users act differently depending on their current context, and hence, that a user can be described by different submodels that represent the user?s preferences within different contexts. Furthermore, our approach takes into account that different applications usually adhere to different semantics
