When numerous agents interact, conflicts may arise. To solve them, different ways canbe used such as cooperation, voting systems or negotiation. The one which interests us in thisthesis is contract-based negotiation over resources. The aim of our work is to conceive a general negotiation model (called GeNCA : GenericNegotiation of Contracts API), and to give an implementation of it....

This paper addresses the problem of negotiation in a complex organizational context and tries to bridge the gap between self-interested negotiation and cooperative negotiation. An integrative negotiation mechanism is introduced, which enables agents to choose any attitude from the extremes of self-interested and cooperative to those that are partially self-interested and partially cooperative. ...

Negotiation is a technique through which two agents having conflicting interests reach an agreement that is beneficial for both of them. Argumentation-based negotiation is a better form of negotiation where one negotiating agent argues with another to justify its position and influences the other agent to follow it. This increases the likelihood and quality of agreement in a negotiation process...

This paper considers the use of logic-based languages for multiagent negotiation. We begin by motivating the use of such languages, and introducing a formal model of logic-based negotiation. Using this model, we define two important computational problems: the success problem (given a particular negotiation history, has agreement been reached?) and the guaranteed success problem (does a particu...

In this paper we present a Markov Decision Process approach which gives agents the ability to learn about other agents' strategies from past negotiation steps. Over time, the agents can update their belief models regarding other agents and use those models to anticipate their own strategies during a negotiation process. The negotiation model described in this paper is devised for an agentbased ...

The Curious Negotiator project aims at the automation (to the extent possible) of the delivery and use of information by negotiation agents in electronic market environment. This chapter presents a framework of using text mining agents to provide processed online information to negotiation agents. It includes a news extraction algorithm, a quantitative process model based on the extracted news ...

In semantic web service composition, the selection can also be performed after negotiating with all the discovered service providers and the negotiation-agreements generated from the negotiation can also be used in the selection process. This paper presents a semantic web service selection and composition model based upon this concept. The paper presents multi-agent negotiation based semantic w...

This paper presents AgentFSEGA experience at the Automated Negotiation Agents Competition 2010. AgentFSEGA is a time-constrained negotiation strategy that learns the opponent’s profile out of its moves. Having at the baseline the Bayesian negotiation strategy [3], AgentFSEGA considers the negotiation time as a resource, being prepared to concede more as time passes. While AgentFSEGA performs we...

This paper analyzed 96 current electronic negotiation models concerning their ability to handle imperfect information situations. The results of the empirical investigation show that most of the negotiation models assume imperfect information situations but mainly related to the negotiation partner. Research on imperfect described environments and negotiation items are not sufficient represente...

With the increasing popularity of e-marketplaces for B2C and B2B e-commerce, intelligent software agents are promising in improving the effectiveness of these markets by autonomously searching for products and negotiating contracts on behalf of the human decision makers. A large number of research has been conducted to develop negotiation protocols and mechanisms for automated negotiations. How...
