Abstract:This paper describes an investigation into the distribution issues surrounding the design and implementation of virtual market places. The paper starts by describing the requirements customers and service providers have from a virtual market place. It is then shown how the requirements deemed most important can be addressed by exploiting the inherent distribution of certain aspects, and by distributing other aspects of such market places. In particular, the paper concentrates on the structuring of the informat… Show more
“…IBMÕs Websphere (SilkRoad) matchmaking environment was the first example of commercial solution that places an explicit emphasis on the matchmaking between a demand and a supply in a peer-to-peer way, which is referred to in [36] as symmetric matchmaking. The environment is based on a matchmaking engine that describes supplies/ demands as properties and rules.…”
In this paper, we present a Description Logic approach-fully compliant with the Semantic web vision and technologies to extended matchmaking between demands and supplies in a semantic-enabled Electronic Marketplace, which allows the semantic-based treatment of negotiable and strict requirements in the demand/supply descriptions. To this aim, we exploit two novel non-standard Description Logic inference services, Concept Contraction-which extends sat-isfiability-and Concept Abduction-which extends subsumption. Based on these services, we devise algorithms, which allow to find negotiation spaces and to determine the quality of a possible match, also in the presence of a distinction between strictly required and optional elements. Both the algorithms and the semantic-based approach are novel, and enable a mechanism to boost logic-based discovery and negotiation stages within an e-marketplace. A set of simple experiments confirm the validity of the approach.

Match-making in virtual markets and trading in distributed systems are similar activities aiming at evaluating a client constraint against a set of available service offers, described in terms of properties. Virtual market systems, however, need elaborate schemes for keeping certain property values dynamically updated. Dynamic property updates can be supported by using the dynamic property concept of the CORBA Trading Service. Specifying, executing and managing the algorithms used to compute the values of the dynamic properties, however, is outside the scope of the related CORBA standard. This paper presents the concept and the implementation of a generic engine which can be used to create, edit, manage and execute dynamic-property evaluation-algorithms. This approach brings about a number of benefits: an improved development environment, a simulation test-bed, improved management and maintenance capability, and a structured way of linking the trading service to legacy systems. The resulting system has been used extensively as part of the ViMP virtual market place set of development tools to create a number of dynamic virtual markets.
“…Using domains and gateways: Organisational boundaries can be seen as a placeholder for many different types of domain boundaries such as remuneration, security, management, etc. where each type of domain boundary requires different actions to be taken when activities cross it [10]. When the workflows of two organisations are linked together, it is possible to exploit the explicit communications between them to install proxy-gateways that deal with the following aspects:…”
Efficient means of electronic interaction are an essential requirement for the integration of different companies' business processes along the value chain. Until recently, this interaction relied on expensive, complex and inflexible solutions, mostly based on EDI or some proprietary means. The high set-up costs and time associated with this type of infrastructure prohibits the dynamic forging of business partnerships, which is of utmost importance to the services industry. The CrossFlow architecture supports the dynamic establishment and enactment of a business relationship between two organisations, based on a contract that specifies this relationship. This is achieved by creating an electronic market where advertising and searching for compatible business partners takes place. This is further enhanced by automating the set-up of the contract enactment and supervision infrastructure, and by connecting them together to allow the business processes of the partners to cross their organisational boundaries.
