© Springer-Verlag Berlin Heidelberg 1992. Formalizing non-monotonic reasoning is a significant problem within artificial intelligence. A number of approaches have been proposed, but a clear understanding of the problem remains elusive. Given the diversity of proof theoretic approaches, we argue the need for frameworks for elucidating key concepts within non-monotonic reasoning. In this paper we consider the preferences, implicit and explicit, that can be seen in a disparate range of non-monotonic logics. In particular, we argue the case for an analysis based on Labelled Deductive Systems for viewing existing approaches to formalizing nonmonotonic reasoning, and for identifying new approaches. For this we introduce the family of prioritized logics -each member being a defeasible logic defined in terms of labelled deduction -that forms the basis of a framework for viewing the nature and mechanization of non-monotonic reasoning.
