Aggregation of Support-Relations of Bipolar Argumentation Frameworks

Weiwei Chen

Abstract: In many real-life situations, individuals may have different opinions on support-relations between arguments. When confronted with such situations, we may wish to aggregate individuals' argumentation views on support-relations into a collective view, which is acceptable to the group. In this paper, we assume that under bipolar argumentation theory, individuals are equipped with a set of arguments and a set of attacks between arguments, but with possibly different support-relations. Using the methodology in social choice theory, we analyze what semantic properties of bipolar argumentation frameworks can be preserved by desirable aggregation rules during aggregation of support-relations.
