Dialogue Model Using Arguments for Consensus Decision Making Through Common Knowledge Formation

Ayslan Trevizan Possebom, Mariela Morveli-Espinoza, Cesar Augusto Tacla

Abstract


Argumentation plays an important role in reasoning and allows the justification of opinions, especially when applied to collaborative decision making. Reaching consensus is not a trivial task where arguments exchanged in a dialogue and common knowledge are important for consensus. This paper presents a model of argumentative dialogue to support the formation of common knowledge in a group of agents that communicate by sending arguments, and proposes a semantics for consensus decision making. The output of the model is a weighted argumentation graph in which semantics is used to decide the preference of the group.
