摘要
In this paper, we study unsatisfiable queries posed to a mediator in an information integration system and expressed in the logical formalism of the information integration system PICSEL2 First, we characterise conflicts as the minimal causes of the unsatisfiability of a query. Then, we produce its set of repairs: a repair is a query that does not generate any conflict and that has a common generalisation with the initial query and is semantically close to it.
