    The Effects of E-commerce on the Structure of Intermediation

    The paper questions the notion that the diffusion of electronic commerce will lead to disintermediation. Rather than interpreting intermediation as a single service it is pointed out that intermediaries can provide a number of services. The analysis based on the New Institutional Economics, Market Microstructure Theory, and Information Economics shows that the three intermediation services studied are, generally, not under threat by the diffusion of electronic commerce. The overall effects on intermediation depend on the relevance of these services relative to others (e.g. order processing) which are supposed to become obsolete.B2C eCommerce, intermediation, new institutional economics

    Supporting Change-Aware Semantic Web Services

    The Semantic Web is not only evolving into a provider of structured meaningful content and knowledge representation, but also into a provider of services. While most of these services support external users of the SW, we focus on a vital service within the SW – change management and adaptation. Change is a ubiquitous feature of the SW. In this paper, we propose a service architecture that embraces and utilises change to provide higher quality services. We introduce pilot implementations of two supporting services within this architecture

    Integration via Meaning: Using the Semantic Web to deliver Web Services

    Get PDF
    Presented at the CRIS2002 Conference in Kassel.-- 9 pages.-- Contains: Conference paper (PDF) + PPT presentation.The major developments of the World Wide Web (WWW) in the last two years have been Web Services and the Semantic Web. The former allows the construction of distributed systems across the WWW by providing a lightweight middleware architecture. The latter provides an infrastructure for accessing resources on the WWW via their relationships with respect to conceptual descriptions. In this paper, I shall review the progress undertaken in each of these two areas. Further, I shall argue that in order for the aims of both the Semantic Web and the Web Services activities to be successful, then the Web Service architecture needs to be augmented by concepts and tools of the Semantic Web. This infrastructure will allow resource discovery, brokering and access to be enabled in a standardised, integrated and interoperable manner. Finally, I survey the CLRC Information Technology R&D programme to show how it is contributing to the development of this future infrastructure

    Combining goal-oriented and model-driven approaches to solve the Payment Problem Scenario

    Motivated by the objective to provide an improved participation of business domain experts in the design of service-oriented integration solutions, we extend our previous work on using the COSMO methodology for service mediation by introducing a goal-oriented approach to requirements engineering. With this approach, business requirements including the motivations behind the mediation solution are better understood, specified, and aligned with their technical implementations. We use the Payment Problem Scenario of the SWS Challenge to illustrate the extension

    Deep pockets, packets, and harbours

    Deep Packet Inspection (DPI) is a set of methodologies used for the analysis of data flow over the Internet. It is the intention of this paper to describe technical details of this issue and to show that by using DPI technologies it is possible to understand the content of Transmission Control Protocol/Internet Protocol communications. This communications can carry public available content, private users information, legitimate copyrighted works, as well as infringing copyrighted works. Legislation in many jurisdictions regarding Internet service providers’ liability, or more generally the liability of communication intermediaries, usually contains “safe harbour” provisions. The World Intellectual Property Organization Copyright Treaty of 1996 has a short but significant provision excluding liability for suppliers of physical facilities. The provision is aimed at communication to the public and the facilitation of physical means. Its extensive interpretation to cases of contributory or vicarious liability, in absence of specific national implementation, can prove problematic. Two of the most relevant legislative interventions in the field, the Digital Millennium Copyright Act and the European Directive on Electronic Commerce, regulate extensively the field of intermediary liability. This paper looks at the relationship between existing packet inspection technologies, especially the ‘deep version,’ and the international and national legal and regulatory interventions connected with intellectual property protection and with the correlated liabilities ‘exemptions. In analyzing the referred two main statutes, we will take a comparative look at similar interventions in Australia and Canada that can offer some interesting elements of reflection

    Agent Technology in Supply Chains and Networks: An exploration of high potential future applications

    Get PDF
    This paper reports on an ongoing research project that\ud is aimed at evaluating how software agents can improve\ud performance of supply chains and networks. To conduct\ud this evaluation, first a framework is developed to classify\ud potential applications of software agents to supply\ud networks. The framework was used in workshop sessions\ud with logistics and information systems experts from\ud industry, software/consultancy and academia to identify\ud promising areas for agents. Based on the framework and\ud the outcome of the workshop sessions, this paper presents\ud promising application areas for the near future and\ud beyond
