面向服务的计算（SOC）是一种新兴的分布式和面向对象的计算范例，它允许在组织内部和跨组织边界构建（描述、发现、组合、编排）自主的、平台无关的计算实体（称为服务）。与以前的任何计算范式不同，SOC注定会对商业领域产生持久的影响，其中包括电子商务，电子政府，电子商务，电子学习，电子健康等。面向服务计算的青年研究人员研讨会系列旨在为来自行业和学术界的初级研究人员提供一个平台。其核心目标是交流有关SOC最新技术和实践进展的信息，并确定该领域的新兴研究主题和未来趋势。继前三次研讨会的成功之后，第四届欧洲面向服务计算青年研究人员研讨会（YR-SOC 2009）引入了两个新事物：它是在英国以外组织的，并引入了一些教程，从而使研讨会成为为期3天的活动。YR-SOC 2009在意大利比萨的CNR信息科学与技术研究所举行，由Maurice ter Beek，Barry Norton，Stephan Reiff-Marganiec和Monika Solanki组织。在这卷的贡献涵盖的方面，如自动化服务组合，上下文感知SOC，面向服务的编程，QoS感知SOC，面向服务的架构，SOC建模和分析，过程管理，Web服务，本体和语义网。
英文摘要：
Service-Oriented Computing (SOC) is an emerging new paradigm for distributed and object-oriented computing by allowing autonomous, platform-independent computational entities (called services) to be built (described, discovered, composed, orchestrated) within and across organizational boundaries. Like no other computing paradigm before, SOC is destined to exert a lasting influence on the business domain, among others (e-commerce, e-government, e-business, e-learning, e-health, etc.).
The Young Researchers workshop series on Service-Oriented Computing is meant to be a platform for junior researchers from industry and academics alike. Its core objectives are to exchange information regarding advancements in the state of the art and practice of SOC, as well as to identify emerging research topics and the future trends in this domain.
Following the success of the previous three workshops, the 4th European Young Researchers Workshop on Service-Oriented Computing (YR-SOC 2009) introduced two novelties: it was organised outside of the UK and it saw the introduction of a number of tutorials, thus making the workshop a 3-day event. YR-SOC 2009 took place at the CNR Institute of Information Science and Technologies in Pisa, Italy, and was organised by Maurice ter Beek, Barry Norton, Stephan Reiff-Marganiec and Monika Solanki.
The contributions in this volume cover aspects such as automated service composition, context-aware SOC, service-oriented programming, QoS-aware SOC, service-oriented architectures, SOC modelling and analysis, process management, web services, ontologies and the semantic web.
