Abstract

Abstract: In the field of collective argumentation, multiple agents may have different knowledge representations and individual preferences. In order to obtain a reasonable collective outcome for the group, either individual frameworks should be merged or individual preferences should be aggregated. However, framework merging and preference aggregation are different procedures, leading to disagreements on collective outcomes. In this paper, we figure out a solution to combine framework merging, argumentative reasoning and incomplete preference aggregation together. Furthermore, a couple of rational postulates are proposed to be the criteria for the rationality of collective outcomes obtained based on our approach.
