摘要
在面向服务计算模式中,传统的UDDI、ebXML服务注册中心无论是服务发现,还是组合与交互方面都面临着信息共享和过程中介的难题.文中结合语义Web(Semantic Web)和社会化网络(Social Networking)技术,显式地定义服务间的交互关系(简称服务关系),并将它们融入到服务注册中心的组织、构建及服务计算过程中,将可用Web服务组织成具有丰富语义信息、基于业务上下文和交互关系的服务生态系统.文章首先分析并定义了参数、操作和服务三个层级的服务关系;接着详细讨论了服务关系挖掘的技术细节,包括Web服务的语义标注、服务关系提取、利用等;最后是相关实验数据及结果分析.将语义推理和关系演算引入到服务发现、组合、交互过程中,可以促进和便利服务计算,也是朝向服务互联网(Internet of Services)迈出的重要一步.
In Services-Oriented Computing(SOC) paradigm,traditional Web service registry,like UDDI and ebXML,has been facing great difficulty in information sharing and process mediation when processing service discovery,service combination and interaction.Combining Semantic Web and Social Networking technology,this paper organizes available Web services into service ecosystem,named Service Network(SN),which explicitly merges abundant semantic information and socialized interactive relations,i.e.Service Relation(SR),into SOC paradigm.Firstly,three different granularities of Web service,including parameter level,operation level and Web-service level,are analyzed and defined.Secondly,the details of Service Mining,which includes Web service annotation,service relations mining and its application and leverage on SOC,are discussed.Last comes the experimental results and analysis.By organizing available Web services into service discovery,composition,and interoperation with abundant semantic information,business context and social relations,SN is firmly believed to be a new infrastructure for SOC and also key effort toward the implementation of "Internet of services".
