Web Service Semantics:

The description of Web services in a machine-understandable fashion is expected to have a great impact in the areas of e-Commerce and Enterprise Application Integration, as it can enable dynamic and scalable cooperation between independently developed systems and organisations. These potential benefits have led to the establishment of an important class of research activities, both in industry and academia, aimed at the practical deployment of declarative, semantically rich service and process descriptions and their use across the Web service lifecycle.
This research, which draws on a variety of fields such as knowledge representation, automated software engineering, process modeling, workflow, and software agents, is happening under several headings, including Semantic Web services, Grid services and Semantic Grid services, and (some aspects of) service-oriented computing. For ease of reference, in this call we refer to this general area of work as Semantic Web services (SWS). We note that here, "Semantic Web" does not denote any particular set of standards, although much work in this area does build on products of the Semantic Web activity at W3C. In addition, many SWS efforts are aligned with rapidly developing commercial Web service standards such as WSDL and UDDI.
Many major challenges need to be addressed in this field. This workshop aims to provide a forum in which to focus on selected core technical challenges for deployment of SWS, and reach a better understanding of the relationships between commercial Web service standards, current SWS research efforts, and the ultimate requirements for full-scale deployment of these technologies. Another major focus will be on the relationship of work on SWS to the needs of business systems, and in particular the needs having to do with publishing policies associated with Web services, such as those discussed at the recent W3C Workshop on Constraints and Capabilities for Web Services (see http://www.w3.org/2004/06/ws-cc-cfp.html). Submissions related to semantics for Grid services are welcome. We particularly seek submissions that demonstrate innovative applications of SWS technologies to the challenges involved in automating online business transactions.
The intended audience includes researchers working on Semantic Web services, Grid services, and related technologies; students interested in these topics; developers of commercial Web services standards (such as those engaged in these activities at W3C and OASIS); and commercial software developers who are investigating how to achieve greater flexibility and automation in the delivery of Web services.
The program will occupy one full day, and will include presentations of papers selected from the full papers category (see "Submissions" below). In some cases, papers may be presented as part of themed discussion panels.
There will be one invited speaker. Subject to time constraints, there may also be a panel of experts on a selected topic.
Registration will be open to all registrants of the WWW conference. Please note that at least one author of each accepted submission must attend the workshop. Submission of a paper is not required for attendance at the workshop. However, in the event that the workshop cannot accommodate all who would like to participate, those who have submitted a paper (in any category) will be given priority for registration.
