A Configurable Matchmaking Framework for Electronic Marketplaces

E-marketplaces constitute a major enabler of B2B and B2C e-commerce activities. This paper proposes a framework for one of the central activities of e-marketplaces: matchmaking of trading intentions lodged by market participants. The framework identifies a core set of concepts and functions that are common to all types of marketplaces and can serve as the basis for describing the distinct styles of matchmaking employed within various market mechanisms. A prototype implementation of the framework based on Web services technology is presented, illustrating its ability to be dynamically configured to meet specific market needs and its potential to serve as a foundation for more fully fledged e-marketplace frameworks

Extending Conceptual Models for Web Based Applications

The next phase envisioned for the World Wide Web is automated ad-hoc interaction between intelligent agents, web services, databases and semantic web enabled applications. Although at present this appears to be a distant objective, there are practical steps that can be taken to advance the vision. We propose an extension to classical conceptual models to allow the definition of application components in terms of public standards and explicit semantics, thus building into web-based applications, the foundation for shared understanding and interoperability. The use of external definitions and the need to store outsourced type information internally, brings to light the issue of object identity in a global environment, where object instances may be identified by multiple externally controlled identification schemes. We illustrate how traditional conceptual models may be augmented to recognise and deal with multiple identities

Extending Conceptual Models for Web Based Applications ⋆

Abstract. The next phase envisioned for the World Wide Web is automated ad-hoc interaction between intelligent agents, web services, databases and semantic web enabled applications. Although at present this appears to be a distant objective, there are practical steps that can be taken to advance the vision. We propose an extension to classical conceptual models to allow the definition of application components in terms of public standards and explicit semantics, thus building into web-based applications, the foundation for shared understanding and interoperability. The use of external definitions and the need to store outsourced type information internally, brings to light the issue of object identity in a global environment, where object instances may be identified by multiple externally controlled identification schemes. We illustrate how traditional conceptual models may be augmented to recognise and deal with multiple identities.

EXECUTIVE SUMMARY Report on Requirements Analysis and State of the Art

This deliverable delineates the state of the art of on process, business, data and epistemological ontologies that are to be used within the DIP 1 project. It presents the Semantic Web Service Usage process as a starting point to motivate the discussion, and to point out where each of the different ontologies fits. Further it introduces the different tools that currently help realizing the different parts of such usage process, and its relation with the different ontologies presented in the state-of-the-art, if any. Finally the requirements in terms of Service description and service requirements for DIP and Workpackage 3 of the DIP project 2 are presented. The intended audience of the deliverable is mainly the DIP project partners, in particular those involved in Workpackage 3 and Workpackage 4. Nevertheless, anyone interested on Service description and how semantically achieve if, may find it of interest. In regard to the impact of this deliverable for DIP, it provides a detailed state of the art on the technology available to describe Services, pointing out the lack or young state o
