Abstract

Epistemic Abstract Argumentation Framework (EAAF) extends Dung's framework (AAF) by allowing the representation of epistemic attacks. So far, the semantics of EAAF has been defined only for a restricted class of frameworks, namely acyclic EAAF, where epistemic attacks do not occur in any cycle. In this paper, we provide an intuitive semantics for (general) EAAF that naturally extends that for AAF as well as that for acyclic EAAF.
