Coalitions of arguments: A tool for handling bipolar argumentation frameworks
Claudette Cayrol, Marie-Christine Lagasquie-Schiex · International Journal of Intelligent Systems · 2009
Bipolar argumentation frameworks enable to represent two kinds of interaction between arguments: support and conflict. In this paper, we turn a bipolar argumentation framework into a meta-argumentation framework where conflicts occur between sets of arguments, characterized as coalitions of supporting arguments. So, Dung's well-known semantics can be used on this meta-argumentation framework to select the acceptable arguments. © 2009 Wiley Periodicals, Inc.
