Abstract
A critical problem in building an information mediator is to design knowledge bases describing the contents of information sources. Concepts which capture abstractions in information sources and which are usable to describe their content must be identified. This paper addresses this knowledge acquisition problem in the context of the PICSEL project, when information sources are relational databases. The main contributions are (1) semi automated techniques for identifying relevant concepts from a database’s conceptual schema, and (2) a set of tools for assisting database administrators in mapping these interesting concepts on to the domain model of the PICSEL mediator.
