The data warehouse is considered to be the best way to organize transactional data. However, as many researches claim data warehouse should be augmented with external textual information. The objective of this chapter is to examine the requirements for profiling in the data warehouse environment. Profiles created in the data warehouse are then utilized to filter information. The goal of the sketched system is to support users in his situated actions. We explore many issues concerning personalization, such as information overflow, user models, and situatedness.
