Responsibility for inconsistency

It is desirable to identify the degree of responsibility of each part of a knowledge base for the inconsistency of that base to make some necessary trade-off decisions on restoring the consistency of that base. In this paper, we propose a measurement for the degree of responsibility of each formula in a knowledge base for the inconsistency of that base. This measurement is given in terms of minimal inconsistent subsets of a knowledge base. Moreover, it can be well explained in the context of causality and responsibility presented by Chockler and Halpern [1]. ? 2015 Elsevier Inc.SCI(E)EI0ARTICLEmukedian@math.pku.edu.cn43-606
