Abstract Argumentation and Explanation

Argumentation and Explanation Christian Strasser and Dunja Šešelja {christian.strasser, dunja.seselja}@UGent.be Centre for Logic and Philosophy of Science, Ghent University Abstract. In this paper Dung’s abstract argumentation framework (cp. [6]) is extended with explanatory capabilities. Further, we investigate bipolar argumentation systems (cp. [4]), incorporate values (cp. [3]) and generalize the systems with sets of attacking arguments (cp. [13]). Different adaptions of standard extension types to explanatory applications are elaborated. Finally our framework is applied to explanation in the context of philosophy of science. We present an argumentation system reconstruction of a notion of unificatory explanation (cp. [14]).
