报告摘要:An intelligent agent often confronts the problem of revising her beliefs upon learning new information. This problem is called belief revision and has attracted much attention in many areas, such as Artificial Intelligence, Databases, and Semantic Web. Possibilistic logic is a weighted logic which is flexible for dealing with both inconsistency and uncertainty. It is closely related to belief revision and nonmonotonic logics. Belief revision in possibilistic logic plays an important role in the theory of iterated belief revision. In this talk, I will present some of our recent work on belief revision in possibilistic logic. I first present an iterative approach to revising knowledge bases in possibilistic logic. I then give a conflict-based revision approach in possibilistic logic. To show the usefulness of our work, I will discuss how belief revision in possibilistic logic is useful to deal with the problem of mapping repair, which is important to improve the quality of ontology mapping.
