A Causality-Based Approach to Assessing Inconsistency for Multi-context Systems

Abstract

Nonmonotonic multi-context systems provide a promising starting point to interlink heterogeneous and decentralized knowledge contexts effectively by modeling the information exchange among contexts instead of logics of contexts uniformly by virtue of bridge rules. Inconsistency handling has been considered as one of the important issues in multi-context systems, since inconsistency makes a multi-context system useless. In this paper, we propose an approach to assessing the responsibility of each bridge rule of a multi-context system for the inconsistency of that system, which helps us better understand roles of bridge rules involved in inconsistency from the point of view of causality.
