Abstract

Abstract: This work introduces Extended Defeasible Logic Programming ( E-DeLP ), a structured argumentation system enabling the expression of reasons for and against using defeasible rules.E-DeLP extends the formalism of Defeasible Logic Programming (DeLP ) by incorporating two new kinds of rules: backing and undercutting rules. In that way, E-DeLP accounts for Toulmin׳s notion of backing and Pollock׳s notion of undercut, two important contributions within the field of argumentation. Thus, E-DeLP constitutes a novel approach, being the first structured argumentation system in providing a unified setting for modeling Toulmin׳s and Pollock׳s ideas simultaneously.
