摘要：
In this paper, we study failing queries posed to a mediator in an information integration system and expressed in the logical formalism of the information integration system PICSEL1. First, we present the notion of concept generalisation in a concept hierarchy that is used to repair failing queries. Then, we address two problems arising while rewriting a query using views. The first problem concerns queries that cannot be rewritten due to a lack of sources, the second one concerns queries that have only unsatisfiable rewritings.
