On a Formal Treatment of Deception in Argumentative Dialogues

摘要

This paper formalizes a dialogue that includes dishonest arguments in persuasion. We propose a dialogue model that uses a predicted opponent model and define a protocol using this prediction with an abstract argumentation framework. We focus on deception as dishonesty; that is, the case in which an agent hides her knowledge. We define the concepts of dishonest argument and suspicious argument by means of the acceptance of arguments in this model. We show how a dialogue including dishonest arguments proceeds according to the protocol and discuss a condition for a dishonest argument to be accepted without being revealed.
