Validity of Attacks Related to Argument Set in Higher-Order Argumentation Frameworks
摘要
In the study of higher-order argumentation frameworks (HO-AFs), the validity of attacks plays a particular role. In this paper, we further study HO-AF theory by focusing on this validity of attacks w.r.t. a set of arguments. Given a set of arguments, the attacks whose sources are in this set are classified into seven types, and the attacks whose sources are out of this set are classified into five types. This classification provides a theoretical foundation for the further study of HO-AF semantics.
