DALEK: a Tool for Dialectical Explanations in Inconsistent Knowledge Bases
Abstract
In this paper we present a prototype of a framework called dalek (DiALectical Explanation in Knowledge-bases). This framework implements dialectical approaches to explain query answers in inconsistent knowledge bases. The motivation behind the prototype is as follows: given an inconsistent knowledge base represented within Datalog +/-, a semantics for handling inconsistency and a query Q, the goal is to explain why Q is accepted or not accepted under such semantics. The explanation takes a dialogical form (cf. [1,3]).
