In this paper we make a contribution to the unification of formal models of defeasible reasoning. We present several translations between formal argumenta-tion frameworks and nonmonotonic logics for reasoning with plausible assumptions. More specifically, we translate adaptive logics into assumption-based argumenta-tion and ASPIC + , ASPIC + into(More)
In structured argumentation frameworks such as ASPIC, rebuts are only allowed in conclusions produced by defeasible rules. This has been criticized as counter-intuitive especially in dialectical contexts. In this paper we show that ASPIC−, a system allowing for unrestricted rebuts, suffers from contamination problems. We remedy this shortcoming by(More)
We extend the <i>ASPIC</i><sup>+</sup> framework for structured argumentation so as to allow applications of the reasoning by cases inference scheme for defeasible arguments. Given an argument with conclusion '<i>A</i> or <i>B</i>', an argument based on <i>A</i> with conclusion <i>C</i>, and an argument based on <i>B</i> with conclusion <i>C</i>, we allow(More)
