The pervasive use of web technologies and online cooperation tools is posing new challenges in the design of recommender systems, requiring now a rapid move from individual to group recommendations. In this paper, a multi-agent system to provide support to small groups of users in their decisionmaking process is presented. In detail, the addressed problem is to find a common solution for a grou...

Electronic commerce has changed the way businesses interacting with consumers and peers. For both B2B and B2C transactions, it becomes more and more important to make the traditional negotiation price mechanism automated and intelligent [1]. Automated negotiation has become the core of the next generation intelligent e-commerce. The main principle is using software agent technology to make the ...

A major challenge in e-negotiation systems (ENS) is that the context of negotiation such as negotiators’ characteristics, negotiation processes and system support varies in each case. This context dependency makes it difficult to apply a single ENS to a wide variety of negotiations. In this paper, to mitigate the context dependency issue, we propose to adopt the componentoriented approach and t...

Research in automated negotiation has traditionally been focusing on the negotiation protocol and strategy design, but little on the implementation related issues such as how to select the best negotiation strategy, especially for problems involving multi-strategy selection. The strategy selection is very important for agent to take risk to achieve better negotiation outcomes. The lack of such ...

Reframing is a sub-type of interest-based negotiation strategy that enhances bargaining by allowing the negotiators to ask for the underlying goal of the negotiation and propose alternative plan(s) which may entail a deal on alternative issues. This paper (i) presents a negotiation protocol that support both alternate offers monotonic bargaining and reframing and (ii) gives a fully computationa...

As the eBusiness environment becomes more comprehensive and dynamic, negotiation processes among companies require more effective electronic support. Despite the progress in research on negotiation systems, the adoption of them has been slow in practice. In particular, the degree of automation achieved in other areas of the business process management has increased the importance of automating ...

We describe a web-based prototype that enhances participatory design by providing participatory negotiation mechanisms between designers and potential end-users of a proposed system. As a module of LINK-UP, a repository for reusable design knowledge, our tool compliments scenario-based design processes, helping designers and potential end-users improve consensus. Negotiation spans a whole desig...

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...
