Integrating Object and Meta-Level Value Based Argumentation

Abstract. A recent extension to Dung's argumentation framework allows for arguments to express preferences between other arguments. Value based argumentation can be formalised in this extended framework, enabling meta-level argumentation about the values that arguments promote, and the orderings on these values. In this paper, we show how extended frameworks integrating meta-level reasoning about values can be rewritten as Dung frameworks, and show a soundness and completeness result with respect to the rewrites. We then describe how value orderings can emerge, or be `formed', as a result of dialogue games based on the rewritten frameworks, and illustrate the advantages of this approach over existing dialogue games for value based argumentation frameworks.
