Persuasive Negotiation Dialogues using Rhetorical Arguments

In persuasive negotiation dialogues, agents, with different interests and goals, exchange proposals that are supported by rhetorical arguments such as threats, rewards, or appeals. The aim of this thesis is to investigate such dialogue systems, where agents can generate rhetorical arguments in order to try to persuade their opponents, and can also construct counter-arguments, which depend on the type of the previously received argument. The main contributions of this work are (i) a persuasive negotiation model that supports this kind of dialogue and (ii) the study the notion of acceptability of these kinds of arguments according to the Dung's definitions.
