ko et al. have recently proposed an abstract framework for default reasoning. Besides capturing most existing formalisms and proving that their standard semantics all coincide, th...
Abstract. Several recent works in the area of Artificial Intelligence focus on computational models of argumentation-based negotiation. However, even if computational models of ar...
Argumentation can serve as an effective computational tool and as a useful abstraction for various agent activities and in particular for agent reasoning. In this paper we further ...
Probabilistic argumentation systems are based on assumption-based reasoning for obtaining arguments supporting hypotheses and on probability theory to compute probabilities of sup...
ABSTRACT. This paper investigates the problem of finding subclasses of nonmonotonic reasoning which can be implemented efficiently. The ability to "define" propositions u...
