Towards a Logic-programming System to Debug ASP Knowledge Bases

By J. C. Acosta-guadarrama


Abstract. This paper is a characterisation in terms of Weak Constraints both for Minimal Generalised Answer Sets and Optimal Answer Sets, of an updates semantics that provides a solid foundation for the implementation of a system to debug knowledge bases. The proposed system can be employed both to identify conflicts with upcoming information from a dynamic changing environment, and to locate the source of conflict from a given inherent inconsistent knowledge base that is static. In addition, this work introduces some formal specifications towards the implementation of a debugging solver with no need to use a total-order semantics. Accordingly, the two-fold contribution of this work is to show a simpler theoretical framework of preferences characterised in DLV, aswellas general foundation to debug both static and dynamic logic programs.
