Attack Semantics for Abstract Argumentation

Serena Villata, Guido Boella, Leendert W. N. van der Torre

Abstract: In this paper we conceptualize abstract argumentation in terms of successful and unsuccessful attacks, such that arguments are accepted when there are no successful attacks on them. We characterize the relation between attack semantics and Dung's approach, and we define an SCC recursive algorithm for attack semantics using attack labelings.
