摘要

In recent years,electronic markets have gained much attention as institutions to allocate goods and services efficiently between buyers and sellers.By leveraging the Web as a global communication medium,electronic markets provide a platform that allows participants throughout the world to spontaneously exchange products in a flexible manner.However,ensuring interoperability and mutual understanding in such a highly dynamic and heterogenous environment can easily become very tricky,particularly if the services and goods involved are complex and described by multiple attributes.In this paper,we present a comprehensive ontology framework that allows the specification of bids for Web-based markets.By expressing utility function policies with a logic-based and standardized formalism,the framework enables a compact bid representation particularly for highly configurable goods and services while ensuring a high degree of interoperability.To facilitate matchmaking of offers and requests in the market,a method for evaluating bids based on logical reasoning is presented.In addition,as proof of concept,we show how the framework can be applied in a Web service selection scenario.
