Data integration and answer set programming

Abstract. The rapid expansion of the Internet and World Wide Web led to growing interest in data and information integration, which should be capable to deal with inconsistent and incomplete data. Answer Set solvers have been considered as a tool for data integration systems by different authors. We discuss why data integration can be an interesting model application of Answer Set programming, reviewing valuable features of non-monotonic logic programs in this respect, and emphasizing the role of the application for driving research.
