Argumentative Alternating Offers

This paper presents an argumentative version of the wellknown alternating offers negotiation protocol. The negotiation mechanism is based on an abstract preference basedargumentation framework where both epistemic and practical arguments are taken into consideration in order to decide about different strategic issues. Such issues are the offerthat is proposed at each round, acceptance or refusal of anoffer, concession or withdrawal from the negotiation. The argumentation framework shows clearly how offers are linkedto practical arguments that support them, as well as howthe latter are influenced by epistemic arguments. Moreoverit illustrates how agents' argumentative theories evolution, due to the exchange of arguments, influences the negotiation outcome. Finally, a generic algorithm that implementsa concession based negotiation strategy is presented.
