An Evolutionary Learning Approach for Adaptive Negotiation Agents

Developing effective and efficient negotiation mechanisms for real-world applications such as e-Business is challenging since negotiations in such a context are characterised by combinatorially complex negotiation spaces, tough deadlines, very limited information about the opponents, and volatile negotiator preferences. Accordingly, practical negotiation systems should be empowered by effective learning mechanisms to acquire dynamic domain knowledge from the possibly changing negotiation contexts. This paper illustrates our adaptive negotiation agents which are underpinned by robust evolutionary learning mechanisms to deal with complex and dynamic negotiation contexts. Our experimental results show that GA-based adaptive negotiation agents outperform a theoretically optimal negotiation mechanism which guarantees Pareto optimal. Our research work opens the door to the development of practical negotiation systems for real-world applications

An Investigation of the Negotiation Domain for Electronic Commerce Information Systems

To support fully automatic business cycles, information systems for electronic commerce need to be able to conduct negotiation automatically. In recent years, a number of general frameworks for automated negotiation have been proposed. Application of such frameworks in a specific negotiation situation entails selecting the proper framework and adapting it to this situation. This selection and adaptation process is driven by the specific characteristics of the situation. This paper presents a systematic investigation of there characteristics and surveys a number of frameworks for automated negotiation

A language for information commerce processes

Automatizing information commerce requires languages to represent the typical information commerce processes. Existing languages and standards cover either only very specific types of business models or are too general to capture in a concise way the specific properties of information commerce processes. We introduce a language that is specifically designed for information commerce. It can be directly used for the implementation of the processes and communication required in information commerce. It allows to cover existing business models that are known either from standard proposals or existing information commerce applications on the Internet. The language has a concise logical semantics. In this paper we present the language concepts and an implementation architecture

Reshaping e-commerce in Thailand: An exploratory study of Internet technology for inter-firm communication adoption in the Thai tourism industry from a cultural fit perspective

The Thai government has emphasised in building technical infrastructure to mimic e-commerce models from western countries. However, evidences shows that Thailand has not yet succeeded in the e-commerce adoption. This study addresses the cultural barriers of Internet technology for inter-firm communication1 adoption in the Thai tourism industry. The results outline various issues emerging from the affect of the Thai’s national culture in business to business communication that impact the B2B e-marketplace2 and e-mail adoption. These are: personal relationship, long term relationship orientation, inter-organisational trust, ability to communicate in English language; and materialism. The data were collected by in-depth interviews with the government and practitioners in the Thai tourism industry

Software Characteristics of B2B Electronic Intermediaries: A Novel Design Science Approach

Long being seen as commercially unsuccessful after the dot-com era, web-based B2B electronic intermediaries are currentlyundergoing a renaissance driven by globalization and an ever increasing cost-pressure on procurement departments ofenterprises. These systems are getting more sophisticated almost by the day, which is also reflected by numerous relatedscientific articles. This development raises the question of the latest characteristics of such systems scientifically described.In order to answer this question, the work at hand depicts the results of a novel design science approach based on a structuredliterature review. The outcomes of this research are i) a state-of-the-art overview of scientifically described softwarecharacteristics of B2B electronic intermediaries, and ii) a taxonomy for structuring software characteristics of this type ofsystems. The results may help practitioners to further develop B2B electronic intermediaries and e-procurement systems, andwill serve as a basis for future research endeavors in the field
