Abstract
AbstractAn approach to formulating relative expressiveness of defeasible logics was introduced in [14]. In this paper we address the relative expressiveness of the well-founded defeasible logics in the framework WFDL and their relationship to the defeasible logics in the framework DL. We show that, in terms of defeasible reasoning, the logics in WFDL have greater (or equal) expressiveness than those in DL, but it is not clear whether they have strictly greater expressiveness. We also show that different treatments of ambiguity lead to different expressiveness in WFDL, as it does in DL.KeywordsLogic ProgramInference RuleLogic ProgrammingStrict RuleSuperiority RelationThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
