Some considerations on mixing semantics in abstract argumentation
This paper discusses the issue of mixing different argumentation semantics in a single Dung's argumentation framework. The general notion of combination schema is defined to model a specific way of mixing argumentation semantics, and several properties that may be desirable for a combination schema are introduced at an abstract level. A specific combination schema is then evaluated in the light of such properties, showing that there are several interesting challenges both from a conceptual and a technical perspective still to be tackled
