Abstract

In this paper we introduce a modular framework for abstract argumentation where the argumentation context, that is information about preferences among arguments, values, validity, reasoning mode (skeptical vs. credulous) and even the chosen semantics can be explicitly represented. The framework consists of a collection of abstract argument systems connected via mediators. The mediators integrate information coming from connected argument systems - possibly solving conflicts within this information - and provide the context used in a particular argumentation module. We show how the framework can be used for hierarchic argumentation as typically found in legal reasoning, and we show how it can be used to model group argumentation processes.
