One of the most serious challenges that web service enabled e-marketplaces face is the lack of formal
support for expressing service requests against UDDI-resident web services in order to solve a complex
business problem. We present a framework in which such a formalization is possible by integrating AI
planning and constraint satisfaction techniques with web service technology. This framework is designed
to handle and execute requests performing planning under uncertainty on the basis of refinement and
revision as new service-related information is accumulated (via interaction with the user and UDDI)
and as execution circumstances necessitate change.
1 Introduction
The current phase of the e-business revolution is driven by enterprises that look to B2B solutions to improve
communications and provide a fast and efficient method of transacting with one another. E-marketplaces are the
vehicles that provide the desired B2B functionality. An e-marketplace is an electronic trading community that
brings multiple customers, suppliers, distributors and commerce service providers in any geographical location
together to conduct business with each other through the exchange of XML based messages (over the Internet)
