Although service-oriented environments and technologies are receiving a great deal of attention in both academic and corporate arenas, the ability to automate the discovery and composition of such services into higher-level capabilities remains elusive. This is funding to support the 4th international web service discovery and composition competition (the WS-Challenge), whose objective is to identify, evaluate and baseline approaches to solving that problem. Building on the success of the first three competitions, which were held in 2005 in Hong Kong, in 2006 in San Francisco, and in 2007 in Tokyo (the latter two with NSF funding), the PI will organize the planning and enactment of the 2008 competition to be held in conjunction with the IEEE International Conferences on Electronic Commerce (CEC 08) and on Enterprise Computing, E-Commerce and E-Services (EEE 08), which will take place in Washington DC in July. The first competition was limited to syntactical matching using the Web Services Description Language (WSDL); participants were required to identify and compose WSDL-specified services based on their input and output messages as specified in a directory of WSDL documents. In 2006 the competition focused additionally on the semantic linking of web services using XML-based semantic notations. The 2007 competition supported the implementation of an initial Web service interface package that served as a platform upon which participants built composition engines, which were then exposed as a Web service; teams were evaluated in terms of architecture and design as well as performance. The 2008 competition will focus on issues relating to dissemination, such as code generalization and creation of APIs that can be used to help new teams access the competition. NSF funding will support participation in the competition of approximately 4 teams from the United States consisting of about 2 students apiece. A small amount is earmarked for travel for the organizers to the competition and the conference registration of the PIs and research assistants.The IEEE International Conferences on Electronic Commerce and on Enterprise Computing, E-Commerce and E-Services bring together researchers and developers from diverse areas of computing. The conferences provide a venue for developers and practitioners to explore and address challenging research issues surrounding e-technology, in order to develop a common research agenda and vision for e-commerce and e-business. The focus is two-fold: to investigate enabling technologies to facilitate next generation e-transformation; and to disseminate application and deployment experience in e-themes such as e-business, e-learning, e-government, e-finance, etc. The CEC/EEE conferences are particularly timely and relevant because they focus on the application of electronic services as they cut across several "e-domains", whereas other conferences tend to either focus on a specific technology or on a single domain.Broader Impacts: The workshop and resulting artifacts will serve as a centralized repository of algorithms, software, and techniques in a timely emerging area. The workshop will provide participants with an opportunity to gain exposure in the community for their innovative work, and to obtain feedback and guidance from senior members of the research community. It will further help foster a sense of community among these young researchers, by allowing them to create a social network both among themselves and with senior researchers at a critical stage in their professional development. The workshop experience will integrate well with the goals of a software engineering education, as participants are evaluated on their design in addition to the performance of their approaches. To engage a broader audience in this year's event, the PI will expand his previously successful efforts to solicit teams from under-represented universities.

尽管面向服务的环境和技术在学术界和企业领域都受到了极大的关注，但是将这些服务自动发现并组合成更高级的功能的能力仍然难以实现。这笔资金用于支持第四届国际web服务发现和组合竞赛（WS-Challenge），其目标是识别、评估和基线化解决该问题的方法。前三届竞赛分别于2005年在香港、2006年在旧金山和2007年在东京（后两届由美国国家科学基金会资助）取得成功，在此基础上，PI将组织策划和实施2008年的竞赛，并将于7月在华盛顿特区举行的IEEE电子商务国际会议（CEC 08）和企业计算、电子商务和电子服务国际会议（EEE 08）同时举行。第一次竞争仅限于使用Web服务描述语言（WSDL）的语法匹配；参与者需要根据WSDL文档目录中指定的输入和输出消息来标识和组合WSDL指定的服务。2006年的竞赛重点是使用基于xml的语义符号的web服务的语义链接。2007年的竞赛支持初始Web服务接口包的实现，该接口包作为参与者构建组合引擎的平台，然后将其公开为Web服务；团队根据架构和设计以及性能进行评估。2008年的竞赛将重点关注与传播相关的问题，例如代码的泛化和api的创建，这些api可用于帮助新团队参加竞赛。美国国家科学基金会将资助来自美国的大约4个团队参加比赛，每个团队由大约2名学生组成。一小部分专款用于主办单位参加比赛的差旅费，以及pi和研究助理的会议注册费用。IEEE关于电子商务和企业计算、电子商务和电子服务的国际会议汇集了来自不同计算领域的研究人员和开发人员。这些会议为开发人员和实践者提供了一个探讨和解决有关电子技术的挑战性研究问题的场所，以便为电子商务和电子商务制定一个共同的研究议程和愿景。重点是双重的：研究使能技术，以促进下一代电子转型；传播电子商务、电子学习、电子政务、电子金融等电子主题的应用和部署经验。CEC/EEE会议特别及时和相关，因为它们侧重于电子服务的应用，因为它们跨越几个“电子领域”，而其他会议往往侧重于特定技术或单一领域。更广泛的影响：研讨会和产生的工件将在一个及时出现的领域中作为算法、软件和技术的集中存储库。研讨会将为参加者提供一个机会，让他们的创新工作在社区中得到曝光，并从研究界的资深成员那里获得反馈和指导。它将进一步帮助培养这些年轻研究人员之间的社区意识，允许他们在他们自己之间以及与处于专业发展关键阶段的资深研究人员建立一个社会网络。研讨会的经验将与软件工程教育的目标很好地结合在一起，因为参与者除了评估他们的方法的性能之外，还会评估他们的设计。为了在今年的活动中吸引更广泛的观众，PI将扩大他以前成功的努力，从代表性不足的大学中征集团队。
