Argumentative Alternating Offers

Abstract

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

Perspectivas da Utilização de Teoria da Mente para o Reconhecimento e Intervenção de Estresse Ocupacional

“…Embora essas observações e eventos de comunicação envolvam aspectos de incerteza [20], como, por exemplo, a comunicação de informações falsas por outros agentes, a limitação da capacidade de observação de outros agentes, entre outros, abordagens de modelagem de teoria da mente tem sido utilizadas com sucesso em muitas aplicações. Aplicações de sucesso incluem simulações sociais para o estudo de atitudes maliciosas de agentes [21], estudos sobre as vantagens da utilização de diferentes níveis de Teoria da Mente em jogos [22,23], como também estudos sobre a modelagem de oponentes em métodos sofisticados de comunicação [24][25][26][27][28].…”

Dispute Resolution Using Argumentation-Based Mediation

“…The decision of whether to trust the negotiating party or not is a part of the strategy of an agent. Different strategies are proposed in [21,22,23]. Apart from the strategy, essential are the reasoning mechanisms and negotiation protocols.…”

Arguing and negotiating using incomplete negotiators profiles

“…In an argumentation-based negotiation (ABN), agents choose offers that are likely to be accepted by the opponent and exchange arguments that support these offers, either based on their own theories (see e.g. [3], [5], [31], [22], [40], [27]), or based on the opponent's profile (see e.g. [28], [41], [15]).…”
