A First Attempt to Allow Enthymemes in Persuasion Dialogs

This paper is a first attempt to define a protocol able to handle enthymemes in a persuasion dialog. An enthymeme is an incomplete argument that uses implicit information either in the support of the argument or even in its conclusion. We propose a protocol that enables the agent to enunciate statements or to utter maybe incomplete arguments, retract or re-precise them. This protocol is designed to forbid inconsistency and redundancy and to ensure that agents listen to each other. The system is illustrated on a small example and some of its properties are presented.
