BackgroundWeb services discovery and composition are two indispensable capabilities required by the emerging service-oriented architecture to enable the next-generation e-Business applications. Following the great success of the first Web Services Challenge held in Hong Kong in March 2005, a similar competition geared towards the management of web services will be held at ICEBE 2005. The competition solicits industry and academic researchers that develop software components and/or intelligent agents that have the ability to discover pertinent web services and compose them to create higher-level functionality. Competition OverviewThis competition will be limited to syntactical matching based on the Web Services Description Language (WSDL). Participants will be required to identify and compose WSDL-specified services based on their input and output messages as specified in a directory of WSDL documents. Although the technical details of this second contest will be similar to the first one, an enlarged web services repository will be used for the evaluation. In the first competition, we found the use of pre-competition evaluations to be useful; therefore we will introduce a special pre-competition evaluation phase for this second contest and the preliminary evaluation results will be released as a form of feedback before the final competition. Each finalist will be required to register and attend the conference to give presentation and demonstration for final evaluation. Competition DetailsCompetitors of Web Services Challenge will be evaluated based on the design and functional capabilities of their component/agent. Design EvaluationParticipants of this competition are required to submit a technical description of their software agent or component of no more than 2 pages. This description and local evaluation will be used to judge and rate the design of the entry. The 2-page description should follow the IEEE Computer Society format as specified by the main conference and will be published as a poster paper in the general proceedings for all accepted finalists. Functional EvaluationThis challenge will be separated into the following two functional competitions. Competition A: Service Discovery CapabilitiesParticipants will be provided with
The participant’s component/agent will be required to find all services that meet the requirements. The service repositories will contain services that do not meet the requirements, services that partially meet the requirements, services that exactly meet the requirements, and services that meet the requirements but also provide additional information. Competition A will be evaluated by the number of services retrieved that either exactly meet the requirements or exceeds the requirements. In addition, the entries will be evaluated on their computational performance in gathering the list of services. Competition B: Service Composition CapabilitiesGiven the same service repository provided in Competition A, the participants will be provided with another discovery request. In this competition, the request can only be fulfilled by the composition of multiple services. The participant will be required to supply the sequence and list of services that meet the requirements. A major assumption in this competition is that the input and output messages of multiple services will match syntactically. Competition B will be evaluated by the number of correctly composed services in addition to the performance of the software agent or component. Participants are encouraged to contact the competition chair to express interest in the contest and the platform they plan to use for the system development.
