Querying inconsistent knowledge bases has attracted a great deal of interest over the last decades.

Abstract

Querying inconsistent knowledge bases has attracted a great deal of interest over the last decades. Also explainability has recently become a prominent problem in AI, and explaining query answers allows users to understand why a query is entailed. In this paper, we address the problem of explaining ontological query answers in the existential rules setting under three popular inconsistency-tolerant semantics, namely, the ABox repair, the intersection of repairs, and the intersection of closed repairs semantics.
