WORKSHOP:WSC2009 Web Services Composition Systems

考虑到最近网络可访问服务或web服务的开始和潜在接受，导致企业集成的组织间协作正在经历一个有希望的进步。商业、学术和政府组织都开始通过公开其底层软件服务来共享它们的功能。数百万甚至数十亿普遍可访问的基于服务的功能的概念不仅对寻找特定的基于消费者的服务的个人很有希望，而且对希望通过合并外部实体的服务来增强自身功能的组织也很有希望。然而，由于理论和应用性质的开放性问题（包括但不限于服务之间潜在的语义和语法不匹配、服务发现的性能约束和容错），自动发现和将此类服务组合为更高级别功能的能力仍然难以实现。这笔资金用于支持第五届Web服务挑战，其目标是为Web服务集成中未解决的问题找到应用解决方案。在前四届比赛成功的基础上（除了第一届以外，其余比赛都部分由NSF资助），2009年的比赛将与IEEE电子商务和企业计算、电子商务和电子服务会议（CEC/EEE'09）一起举行，该会议将于2009年7月20日至23日在奥地利维也纳举行。NSF基金将支持来自美国的大约5支队伍参加比赛，每支队伍由大约2名学生组成。其中一小部分将用于组织者参加比赛的差旅费和会议注册费。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，因为它们跨越了几个电子领域。而其他会议则倾向于关注特定技术或单一领域。作为今年自愿分担费用的一种方式，会议将为WSC2009的组织者和所有参与者提供特别的降低注册费。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。在今年吸引更广泛的受众？在这次活动中，PI将扩大他之前成功的努力，从代表性不足的大学招募团队。

Inter-organization collaboration resulting in enterprise integration is experiencing a promising advancement considering the recent inception and potential acceptance of network-accessible services, or web services. Commercial, academic, and government organizations alike are beginning to share their capabilities via the exposition of their underlying software services. The notion of millions or even billions of universally accessible service-based capabilities is not only promising to the individual looking for a specific consumer-based service but also to organizations hoping to enhance their own capabilities by incorporating the services of external entities. Yet the ability to automate the discovery and composition of such services into higher-level capabilities remains elusive, due to open issues of both a theoretical and applied nature (including, but not limited to, potential semantic and syntactic mismatch among services, performance constraints on service discovery, and fault tolerance).This is funding to support the 5th Web Services Challenge, whose goal is to find applied solutions to unresolved issues in web service integration. Building on the success of the first four competitions (all but the first of which were funded in part by NSF), the 2009 competition will be held in conjunction with the IEEE Conferences on Electronic Commerce and on Enterprise Computing, E-Commerce and E-Services (CEC/EEE'09), which will take place in Vienna, Austria, on July 20-23, 2009. NSF funds will support participation in the competition of approximately 5 teams from the United States consisting of about 2 students apiece. Small amounts are earmarked for travel of the organizers to the competition and for their conference registration fees.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. As a means of voluntary cost sharing this year, the conference will be providing a special reduced registration rate for the organizers of and all participants in WSC2009.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.
