Knowing each other in argumentation-based negotiation

Argumentation-based negotiation has emerged as an important topic in multi-agent systems over the last years. Although there are many studies of frameworks that enable agents to negotiate through the exchange of arguments, there is a lack of reasoning methods that employ the (usually incomplete) knowledge an agent may have about his opponent. This work addresses this issue by providing a reasoning mechanism that allows negotiating agents to take into account information about their counterparts. Thus an agent may support his own decisions by using arguments that are meaningful for his opponent. Experimental results highlight the impact of the proposed approach in the negotiation process.
