Weak Conditional Logics of Normality
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...

Experimenting with Nonmonotonic Reasoning
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...

What Is a Skeptical Proof?
Abstract. We investigate the task of skeptically reasoning in extensionbased, nonmonotonic logics by concentrating on general argumentation theories. The restricted applicability o...

The Abnormality Predicate
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...

On the computational complexity of assumption-based argumentation for default reasoning
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...
