....can alter dynamically over time. Closer to our approach are frameworks that explicitly address the need for agents to reach an agreement or consensus. Typically, consensus is reached through a process of goal revelation and information exchange, loosely categorized under the label negotiation [70, 14, 87, 52, 8]. As an example, the PERSUADER system [86, 87] uses negotiation to find a compromise that is acceptable to the agents in conflict. Their goals might not be totally satisfied by the final agreement. The negotiation process can be seen as a search in a dynamic space consisting of the agents ....

An other existing approach to negotiation via dialogue, that makes use of an argumentation system, is that of [15], and more recently [7] where the authors adopt a modal logic approach and focus on the mental states of agents that move towards an agreement, and on the way to persuade a counterpart in order to foster cooperation. As far as auctions, there is much work on mathematical models, and protocol ....

....are assumed to have complete knowledge of the payoff matrix, and hence of the other agents preferences, and also that precise utility values can be provided. Our approach inherently assumes a partial information perspective and is more qualitative in nature. Sycara s work on the Persuader system [41] employs argumentation as part of a system that operates in the domain of labour negotiations. Although demonstrating the power and elegance of the approach, her system has a centralised arbitrator to handle the disagreements and is thus less general than ours. This work led to sub28 sequent ....

The goal of DPS is to create a net of coarse grained cooperating agents that act together to solve a single task, such as monitoring a network of sensors [11] In DPS generally, the problem is divided into tasks, and intelligent solvers are designed to solve these tasks.

This feature distinguishes collaborative negotiation from non collaborative negotiation such as labor negotiation [Sycara, 1989] . As shown in Table 1, our corpus analysis also found that, in most cases where a proposal is rejected and modified, the agent directly addresses the main (and oftentimes only) proposition during conflict resolution. However, about 20 of the time, instead of directly addressing the main ....
