Logic presents itself as a major tool in the development of formal descriptions for agentbased systems; indeed, Logic Programming (LP) and specially Extended Logic Programming (ELP) provide a powerful tool for the development of such systems, besides being mathematically correct (and subject to proof) are easy to prototype. On the other hand Electronic Commerce (EC) poses new challenges in the ...

Observers of the Electronic Commerce (EC) landscape often comment on the prospects for disintermediation. Other observers note that the nature of EC will create new kinds of intermediaries, termed “cybermediaries”, who would occupy positions in Internet channels between producers and consumers. The word coined to describe this is “reintermediation”. In either case, traditional retailers would b...

We propose that virtual enterprises can be enabled by extending the existing, and evolving, electronic commerce (EC) infrastructure. This incremental approach to virtual enterprises, based on fairly mature technology and standard services, has the obvious advantage over entirely ad hoc solutions of reducing risks and investment costs. To support this view, we present a general multidimensional ...

Electronic Commerce (EC) has been an important application of information and communication technology since several years. But, it has been the emergence of the world-wide available Internet and its several services which makes EC the real killer application of our days [Pyle96]. In its most general definition, EC comprises all selling and buying activities on the Internet. According to a stud...

Ontology is an essential element for the agent system. The agent can share its knowledge and communicate with each other with it. As the agent system is more widely applied, the importance of ontology is increasing. Though there were some approaches to construct ontology, it was too far to satisfy practical needs. In this paper we have constructed an Ontology Server, which provides ontology ada...

Companies employ the World Wide Web (Web) to gather and disseminate information to and from actual and potential customers and increasingly for endconsumer business transactions through Electronic Commerce (EC). Online barriers limit or eliminate Web accessibility for many potential customers with access challenges. It is difficult to establish, develop and manage relationships with potential c...

Electronic commerce (EC) development takes place in a complex and dynamic environment that includes high levels of risk and uncertainty. This paper proposes a new method to assess the risks associated with EC development using multi-criteria decision-making techniques A model based on analytic hierarchy process (AHP) and the technique for order of preference by similarity to ideal solution (TOP...

this paper describes the development of a fuzzy decision support system (fdss) for the assessment of risk in e-commerce (ec) development. a web-based prototype fdss is suggested to assist ec project managers in identifying potential ec risk factors and the corresponding project risks. a risk analysis model for ec development using a fuzzy set approach is proposed and incorporated into the fdss....

This paper focuses on the slowness of diffusion of electronic commerce (EC), particularly in the business-to-consumer side. The theme is approached by analysing emerging Web-services in the travel services industry. We report on a field study of Web-sites of 294 travel agencies, tour operators and transportation services companies. By surveying and evaluating the current services we hope to she...

Trust is widely recognized as an essential factor for the continual development of business to customer electronic commerce (B2C EC). Many trust models have been developed, however, most are subjective and do not take into account the vagueness and ambiguity of EC trust and the customers’ intuitions and experience when conducting online transactions. In this article, we develop a fuzzy trust mo...
