A default conditional α → β has most often been informally interpreted as a defeasible version of a classical conditional, usually the material conditional. That is, the intui...
In this paper, we describe a system, called TheoryBase, whose goal is to facilitate experimental studies of nonmonotonic reasoning systems. TheoryBase generates test default theor...

Abstract. We investigate the task of skeptically reasoning in extensionbased, nonmonotonic logics by concentrating on general argumentation theories. The restricted applicability o...
We suggest a new representation of defeasible entailment and specificity in the framework of default logic. The representation is based on augmenting the underlying classical lan...
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...
