This article introduces the notion of dynamics into the conceptof abstract argumentation frameworks, by including theconcept of evidence to rule the validity of arguments whenconsidering a particular situation. The proposed formalismis a refinement of Dung’s abstract argumentation framework,to which many extensions have been defined. Our claim isthat this idea could be enriched by the dynamic theory we areproposing. The main subject of this paper is the definition ofthe Dynamic Argumentation Framework, from which a staticinstance can be obtained. This instance is shown to be equivalentto the widely adopted Dung’s framework. Therefore,multiple frameworks can be obtained from different instancesof a given dynamic framework.
