Abstract

In this paper we motivate and formalise a framework that organises Dung argumentation frameworks into a hierarchy. Argumentation over preference information in a level n Dung framework is then used to resolve conflicts between arguments in a level n-1 framework. We then re-examine the issue of Dung's acceptability semantics for arguments from the perspective of hierarchical argumentation.
