基于社交网络和关联数据的服务网络构建方法

Constructing method of service network based on social network and linked data

网络中可用服务的急剧增加对面向服务计算技术的发展起到了极大的推动作用。针对服务的规模和利用率远没有达到预期,以及服务之间交互关系的复杂性问题,提出基于社交网络和关联数据的服务网络构建方法。首先,结合社交网络和关联数据方法提出服务网络(SN)的概念,以提高服务的规模及利用率;其次,为了提升服务发现的可行性及有效性,构建服务网络中的服务社区;然后,形式化地表述服务网络中服务之间的关联关系和属性,以解决服务之间互操作问题;最后,结合旅游服务网络案例研究分析所提出的方法。研究结果表明,基于社交网络和关联数据的方法可有效解决网络服务利用率低以及服务关系复杂性的问题。

An increasing large number of services are available in the network, which plays a great role in promoting the development of service-oriented computing technology. Concerning the problems that services scale and utilization were far from initially expected, and the interactions of making the services work together were complicated, a method for constructing service network based on social network and linked data was proposed. First of a11, in order to improve service scale and utilization, the concept of Service Network （SN） combining social network and linked data was proposed. Secondly, the service community in the service network was established for elevating the feasibility and effectiveness of service discovery. Then, in order to solve the problem of service interoperation, the service relationship and property were formally expressed in service network. Finally, a case study of tourism service was used to analyze the proposed method. The analysis results show that the efficiency and feasibility of the proposed method are validated to solve the problems of low service utilization and complex service relationship.
