A Dynamic Argumentation Framework

This article introduces the notion of dynamics for abstract argumentation frameworks. We consider evidence as the basis from which arguments may be considered valid. The proposed Dynamic Argumentation Framework (DAF) is a refinement of Dung's abstract framework (AF), enriched with additional features. Since an instance of a DAF is equivalent to an AF, the former could be viewed as a template to build different AFs, applying the same knowledge to different situations. This equivalence is important, as we can take advantage of the vast amount of study on argumentation semantics for AFs to apply it to our approach. The DAF's aim is to provide a well-structured knowledge representation tool that allows for the definition of dynamics-aware argumentation-based systems.
