Session Scope
Service-Oriented Computing is one of the most promising software engineering trends for future distributed systems. Pushed by major industry players and supported by many standardization efforts, Web services are a prominent implementation of the service-oriented paradigm. They promise to foster reuse and to ease the implementation of loosely coupled distributed applications.
Though Web services are appealing especially in the area of enterprise application integration, the idea of service oriented computing and the envisioned availability of thousands of services can not be fully leveraged as long as service oriented applications must be created and maintained manually. Semantic technology may help here, by lifting service oriented applications to a new level of adaptability and robustness. By using semantic annotations to describe services and resources, the tasks of service discovery, selection, negotiation, and binding could be automated.
Currently there are many different approaches to semantic Web service descriptions and many frameworks built around them, yet a common understanding, evaluation scheme, and testbed to compare and classify these frameworks in terms of their abilities and shortcomings is still missing.
The SWS Challenge
The goal of the ongoing Semantic Web Service Challenge (www.sws-challenge.org) is precisely to develop this common understanding of various technologies intended to facilitate the automation of mediation, choreography and discovery for Web Services using semantic annotations. This explores trade-offs among existing approaches, reveals the strengths and weaknesses of the proposed approaches as well as which aspects of the problem space are not yet covered.
The series of three workshop so far has provided a forum for discussion based on a common application. The SWS Challenge focuses on the use of semantic annotations: participants are provided with semantics in the form of natural language text that they can formalize and use in their technologies. Being a challenge rather than a contest, workshop participants mutually evaluate and learn from each others' approaches.
The challenge has participating groups from industry and acadfemia developing software components and/or intelligent agents able to automate mediation, choreography and discovery processes between Web services. It has presented two sets of problem scenarios from a B2B application domain (with increasing degrees of complexity) as common application to all the participating groups. This way the trade-offs among existing approaches that facilitate the automation of mediation, choreography and discovery for services using semantic annotations can be explored.
- The mediation scenario problems concern making a legacy order management system interoperable with external systems that use a simplified version of the RosettaNet PIP3A4 specications.
- The discovery scenario problems concern the dynamical discovery, selection, binding, and invocation of the most appropriate shipment service for a set of given shipment requests.
At the SWS workshops the approaches were presented and demonstrated, but also the code was jointly reviewed. The common application helped developing a profound mutual understanding of each other's technology and the collaborative discussion of the profiles of the various approaches. The participants developed an evaluation scheme that classifies the functionality and the agility offered by the various approaches, and applied it to the participating technologies. Meanwhile there is a good variety of approaches, a good level of maturity of the proposed solutions, and a good understanding of the profiles of the methods.
The Session
This special session will present in a coherent way the results achieved so far. It will contain an introduction to the problem, to the Challenge methodology developed during the workshops and report on the experience gained so far. Papers in the session will focus primarily on presenting the results of the collaborative comparison of different approaches. Thus the session will not only provide an overview over existing approaches via their application to a common problem set, but also a unique qualitative comparison of these approaches. Beside presenting the results of the SWS-Challenge the session seeks papers describing other approaches to the evaluation of semantic web service frameworks. Such submissions should explain the approach taken, point out how a bias towards a specific technology has been avoided and describe the experiences, results and lessons learned.
