Nowadays, many researches are being been made for the development of new transaction system in an effort to transform current off-line system into on-line one. However, these researches mainly focuses on ordinary commercial transaction system, i.e. the one that supports fixed price transaction, in which consumers usually ought to buy goods at the price offered by sellers. Accordingly, more stud...

Prior research has indicated that groups using Negotiation Support Systems (NSS) achieve better outcomes than face-toface groups. However, these studies indicate that the main source of value added is provided by the Decision Support System (DSS) component, with very little additional value provided by the electronic communication component. This study examines the value added by the electronic...

This paper introduces cognitive negotiation support which is based on the restructurable modeling approach. Cognitive support systems allow for the integration of qualitative and quantitative representations, support basic approaches to decision making, and provide descriptions of alternative realities. The development of representations and the process of their modifications are illustrated wi...

We describe a web-site containing material and tools for learning mathematical models of negotiation analysis and discuss students' experiences of its use. The site is part of our general e-learning decision making site, www.dm.hut.fi. The negotiation analysis section provides an introduction to the theory and gives online practice in negotiation support. The material consists of theory section...

Negotiation Support Systems offer a sophisticated support of electronic negotiations. During a negotiation process, different types of conflicts can occur. Up to a certain level, they can be constructive, afterwards they become destructive. Such escalating conflicts should be handled and resolved. In this paper, the potential and challenges of conflict resolution support for such type of negoti...

We present three scenarios concerning access to documents in three real world fields of application, which have in common that they are very difficult to support with classical anticipative access control systems. We show, how based on a highly configurable notification and negotiation service, which is tightly integrated with a classical access control system – the common permission and denial...

This study presents a novel model that integrates agent negotiation into constructive learning for enhancing interaction efficiency between learner and instructor and promoting learning motivation. A constraint-based agent negotiation mechanism is employed to support a web-based learning environment in which instructor can perceive learners’ feedback and receive suggestion about pedagogical str...
