This paper presents a computational approach to modelling pragmatic and semantic aspects of multi-issue bargaining dialogues. The model accounts for actions that shape negotiation structure and actions that express negotiation strategies. The model also accepts a number of negotiation moves as specifications of the semantic content of the performed taskrelated dialogue acts. The designed dialog...

This paper presents the design and implementation of negotiation agents that negotiate with other entities for acquiring multiple resources. In our approach, agents utilize a time-dependent negotiation strategy in which the reserve price of each negotiation issue is dynamically determined by 1) the likelihood that negotiation will not be successfully completed (conflict probability), 2) the exp...

In this paper, I present my ongoing research on agent-based negotiation teams. An agent-based negotiation team is a group of two or more agents with their own and possibly conflicting goals that join together as a single negotiation party because they share a common goal that is related to the negotiation. Our research goal is to provide agent-based solutions for problems which may need negotia...

An offer in a fuzzy negotiation model is rejected or accepted by acceptability based on fuzzy set theory and membership functions. Since different issues have different effect on negotiators, the combined concession in the multi-issue negotiation for negotiators and negotiation agents and genetic learning mechanism are adopted to update their beliefs about incomplete information. The fuzzy nego...

One of the challenges, of designing a negotiation agent, is to provide a unified framework. This allows heterogeneous agents to interact, despite their underlying architecture differences. In this paper, we presented a unified framework for e-commerce negotiation agent. The unified framework supports not only one-to-one and one-to-many negotiation, but also many-to-many negotiation. In supporti...

In negotiation the exchange of contextual information is as important as the exchange of specific offers. The curious negotiator is a multiagent system with three types of agent. Two negotiation agents, each representing an individual, develop consecutive offers, supported by information, whilst requesting information from its opponent. A mediator agent, with experience of prior negotiations, s...

Negotiation is a complex process aimed at reaching agreement about the exchange of goods or services. Although a daily activity, few people are effective negotiators [10]. Existing Negotiation Support Systems (NSS) can improve the human performance in negotiations and increase the number of win-win outcomes if the negotiation space is well-understood [5]. However, to develop the negotiation spa...

In the current research and development of e-commerce systems, the negotiation process and the enforcement / execution of the results of the negotiation process are often treated as separated business activities. The separation creates an integration problem because these activities should be integral parts of most business transactions. In this paper, we have proposed an approach to categorizi...

We introduce a global specification language for distributed negotiations, a recently introduced concurrent computation model with atomic negotiations combining synchronization of participants and choice as primitive. A token game on distributed negotiations determines reachable markings which enable possible next atomic negotiations. In a deterministic distributed negotiation, each participant...
