摘要
Defeasible logic is an efficient non-monotonic logic for defeasible reasoning. It is defined through a proof theory, and has no model theory. In this paper a denotational semantics is given for defeasible logic, as a step towards a full model theory. The logic is sound and complete wrt this semantics: but the semantics is not completely satisfactory as a model theory. We indicate directions for research that might resolve these issues.
