Abstract

This paper presents a semantics for dynamic argumentation frameworks. A dynamic argumentation system involves the concept of execution of an argumentation affecting subsequent arguments. Although such dynamic treatment is necessary to grasp the behavior of actual argumentation, semantics proposed to date can only handle the static aspects. Here, we present a new semantics that fits dynamic argumentation. We discuss what properties hold and explain how to compute changes in the set of acceptable arguments, depending on the presentation order of arguments.
