Group context-based adaptations for recommendation

In groupware or community based applications the user interface is usually static or tailored to the individual user’s needs. Newer developments try to adapt the user interface automatically in regard to user contexts. Even though these techniques are proven useful, there exists no contextadaptive system taking the current context of a group or community in regard. In this paper, we briefly discuss the problems of defining context and present our understanding of context as a subset of the current information state. We provide an exemplary scenario to present different approaches how to compute group contexts based on semantic models and user contexts, and the consequences for the adaptation goals - in the interface or through changes at system functionalities or tools. We additionally discuss the problems occurring at evaluating adaptations and the value of group context for collaborative work.
