In systems composed of multiple autonomous agents, negotiation is a key form of interaction that enables groups of agents to arrive at a mutual agreement regarding some belief, goal or plan, for example. In general, multi-linked negotiation (including both the directly linked and the indirectly linked relationships) describes situations where one agent needs to negotiate with multiple agents ab...

This is a study of the points of view in a negotiation. Policy modeling, a new method for understanding utilities, is discussed. With policy modeling, the importance weights, subjective values, and a trade-off strategy were estimated from prenegotiation ratings. With these parameters, the values of unfamiliar offers made during a negotiation then also could be estimated. The utility models of t...

Endowing the negotiation agent with a learning ability such that a more beneficial agreement might be obtained is increasingly gaining emphasis in agent negotiation. In this paper, we present a novel bilateral negotiation model based on Bayesian learning to enable self-interested agents to adapt negotiation strategies dynamically during the negotiation process. Specifically, we assume that two ...

The virtual enterprise (VE), which is formed according to some business opportunities through the collaboration of supply chain partners, is an effective way of business operation in the dynamic global market. This paper proposes an automated negotiation protocol for multi-agent system (MAS) based virtual enterprises. Firstly, to facilitate the functional integration of VEs, a MAS framework is ...

In this paper we propose an efficient negotiation agent system that guarantees the reciprocity of the attendants in a bilateral negotiation on the ecommerce. The proposed negotiation agent system exploits incremental learning based on artificial neural networks to generate counter-offers and is trained by the previous offers that have been rejected by the other party. During a negotiation, the ...

A major challenge in developing an e-negotiation system (ENS) is that the context of negotiations such as negotiators’ characteristics, negotiation processes, negotiation rules, and social implication are different case-by-case. This context dependency makes it difficult to develop a general ENS applicable to wide variety of negotiation problems. In this paper, in order to mitigate the context ...

Negotiation is the process whereby two (or more) individual agents with conflicting interests reach a mutually beneficial agreement on a set of issues. In negotiation the exchange of information is as important as the exchange of offers. During a negotiation, an agent may actively acquire contextual information that it may, or may not, choose to place on the negotiation table. Contextual inform...

This paper describes our ongoing R&D effort in developing a replicable, Web-based negotiation server to conduct bargaining-type negotiations between clients (i.e., buyers and sellers) in e-commerce. Multiple copies of this server can be paired with existing Web-servers to provide negotiation capabilities. Each client can select a trusted negotiation server to represent his/her interests. Web-ba...

This paper presents a plan-based model that handles negotiation subdialogues by inferring both the communicative actions that people pursue when speaking and the beliefs underlying these actions. We contend that recognizing the complex discourse actions pursued in negotiation subdialogues (e.g., expressing doubt) requires both a multi-strength belief model and a process model that combines diff...

This position paper focuses on the content negotiation and adaptation of services in heterogeneous environment and this using the concept of universal profiling. We discuss our vision to achieve an advanced content negotiation. For this, we define a profiling schema that includes the utile description of the entire component that can participate in the final deliverance of services. The defined...
