BReLS: a System for Revising, Updating, and Merging Knowledge Bases

Paolo Liberatore

Workshop notes of the Third Workshop on Nonmonotonic Reasoning, Action, and Change (NRAC'99)

Three distinct operations have been introduced so far to the extent of amalgamating knowledge coming from different sources: revision, merging, and update. In this paper we present a framework in which it is possible to perform these three operations at the same time. We show some examples in which this is actually necessary, and thus cannot be dealt by existent systems. The framework has been implemented, and the examples shown in this paper (as well as other examples from the belief revision literature) have been successfully tested. To our knowledge, this is the first implemented system able to perform revision, merging, and update at the same time.
