Workshop Description

Research on Semantic Web Services has gained a lot of momentum over the past few years, demonstrating its viability for dynamic service discovery, selection, composition, negotiation, mediation and invocation over the Web. However, design and development of Semantic Web Services tools and applications is still a new practice not only within the research community but also in industry. Software developers need to deal with new kinds of artifacts, e.g., semantic descriptions, ontologies, complex rules, formulas and facts, new kinds of operations, e.g., mapping, merging, transformation, querying and reasoning, and probably new kinds of user interactions and visualizations.

Best practices, methodologies and tools to help in dealing with these artifacts and operations in Semantic Web Services development are thus in high demand. Moreover, there are few scientific methods of comparing and evaluating the strengths and weaknesses of functionalities claimed by different approaches.

The SWS Challenge has been one of the first initiatives providing a number of real world problem scenarios and a standard testbed to assess the robustness and applicability of proposed technologies, without which progress in scientific development and in industrial adoption in Service Oriented Architectures (SOAs) could be critically hindered. The evaluation of SWS approaches and tools is especially important for informing the proper implementation of web services so that they can be used by businesses in a largely technology-indpendent manner.

The SWS Challenge is open to all technologies and approaches, including hard-coded programming, logic-based frameworks, and/or model-driven techniques. All of these have proven successful to various degrees though we expect to see more differentiation as the surprise problems become more challenging.

This SWS Challenge workshop, in conjunction with ECOWS 2009, provides a forum for researchers and developers of Semantic Web Services to present and discuss the latest progress in the area and to discuss the gap between research, required methodologies, tools and their applications in practice.

The workshop invites the submission of papers related to the topics of interest below as well as papers describing a solution for one of the SWS-Challenge scenarios. Participants are also invited to propose industrially-relevant new scenarios to be incorporated into the official SWS Challenge testbed.

The SWS Challenge is associated with the one-year W3C SWS Testbed Incubator, which has issued a W3C Incubator Group Report about the evaluation methodology developed within the SWS Challenge. Participants submitting papers on evaluation methodology are encouraged to get familiar with the the W3C SWS Testbed Incubator Report.

This workshop continues a series of SWS Challenge workshops which is an ongoing and continuous experiment in evaluating the functionality of SWS technologies.

We are very happy to announce the official release of a new SWS discovery scenario designed and contributed by CEFRIEL and the University of Bicocca. Together with the previous Scenarios this scenario is open for participation and evaluation at this workshop.

Invited Talk

We are very pleased to announce that Prof. Dr. Matthias Klusch, DFKI Saarbrücken, Germany confirmed to present a keynote on "Semantic Service Retrieval: Tools, Evaluation and Challenges". Matthias is well known for his successful initiatives towards standard SWS benchmarks. Among many other activities, he is the primary organizer of the S3 Contest on Semantic Service Selection and also leads the development of OWLS-TC and SAWSDL-TC, the so far most widely used SWS test collections

Paper Submission

Prospective authors are invited to submit papers for presentation in any of the areas listed above. Papers must be in English and formatted according to the Springer LNCS guidelines. We solicit the submission of the following types of papers:

Short research papers (max 6 pages)
Position papers (max 6 pages)
Full research papers (max 12 pages)
Full SWS-Challenge solution papers (max 14 pages)

SWS-Challenge solution papers describe an implemented solution to any of the SWS-Challenge problem scenarios. They should describe the technology employed for the solution but focus on how that technology was actually used to solve the Challenge problems. The reader should be able to understand a particular solution in theory and practice by reading a solution paper. Additional submission of the code and documentation of the solution is strongly encouraged. SWS-Challenge solutions will be code reviewed and certified on the second workshop day.

For SWSC solution papers we allow to submit a short preliminary version (typically 4-6 pages) instead of the full version by the general submission deadline. That is, authors of solution papers have two options:

If they want more time, they submit a short preliminary paper by the general submission deadline and the full solution paper latest one week prior to the workshop.
If they want to avoid the effort of preparing two papers, they submit the full solution paper by the general submission deadline already (and do not submit a short preliminary paper).

Acceptance to present a SWSC scenario solution at the workshop will be based on whatever paper has been submitted by the general paper deadline.

Accepted papers will be published in CEUR Workshops Proceedings.

Papers that are not presented at the workshop will not be included in the proceedings. Solution papers describing solutions that are not demonstrated at the workshop will also not be included in the proceedings.

Papers need to be submitted to the Easy-Chair installation for the workshop.

Code Submission Guidelines

Participants providing a solution for one of the SWS Challenge Scenarios (see below) should contact the person in charge before the main paper submission deadline.

SWS-Challenge Certification Results

**Evaluation Results from this Workshop**
Problem Level	Novay (formerly, Telematica Insituut) & University of Twente (Solution Details)	University Milano-Bicocca & Cefriel (Solution Details)
Payment Problem Mediation	√¹
Logistics Management Discovery Goals A-C
Logistics Management Discovery Goal D1		√²
Logistics Management Discovery Goal E1		√²

¹Mediator runs in simulation environment only. It is accessible from the testbed and properly interacts with Moon and Blue, but it has not been transformed to BPEL and been made available as a web service.

²The representation and execution of the A.T.P. and A.D.R. regulations as well as the preference policies was solved correctly, but there were bugs in the underlying functional discovery with respect to the computation of shipping times and the corresponding filtering of providers.

Registration and Fees
