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...
We present a new approach to dealing with default information based on the theory of belief functions. Our semantic structures, inspired by Adams' -semantics, are epsilon-beli...

In recent years, a number of different semantics for defaults have been proposed, such as preferential structures, semantics, possibilistic structures, and
In this paper weexplore the computationalaspects of Propositional PowerDefault Reasoning (PDR),a form of non-monotonicreasoning whichthe underlyinglogic is Kleene's3-valued p...
This article provides an experimental analysis of the possibilistic handling of default rules. Three different nonmonotonic consequence relations are considered: minimum specifici...
