【摘要】 随着SaaS和SOA技术的快速发展,互联网上分布的服务资源日趋丰富,与此同时,网络用户数量的激增导致用户需求呈现出个性化和多样化的趋势,因此,如何快速选择合适的候选服务,以满足用户的个性化需求成为一个亟待解决的关键问题。针对领域共性需求构造的领域模型库可以在对个性化需求进行服务定制过程中发挥重要的重用作用。面对用户的个性化需求,在领域模型库中进行搜索可以快速地找到候选服务解决方案,进而可以在共性解决方案的基础上进行个性化选择与定制。在领域模型库的基础上,基于RGPS关联元模型,提出一种按需服务选择方法。该方法根据RGPS间的关联规则及本体提供的语义标识,针对不同的需求构造相应的需求描述模板,可以快速找到匹配度较高的候选服务,从而为用户进行按需选择与定制提供基础。最后通过案例分析说明了该方法的有效性。更多还原

【Abstract】 With the rapid development of SaaS and SOA technology,the service resources dispersed on the internet are increasingly rich.At the same time,the enormous increase of users cause users’ requirements to present the trend of individuation and diversity.Therefore,how to rapidly select the appropriate candidate services becomes a key issue. Domain model libraries obtained by modeling common requirements in specific domains play an important reusable role in the process of service customization to personalized requirements.As for personalized requirements of users, candidate services solutions can be found quickly by searching the domain model libraries,so as to realize the personalized selection and customization based on common solutions.On the basis of domain model libraries,this paper proposed an on demand service selection approach based on the metamodel of RGPS association.According to the relationships among RGPS and semantic annotation provided by ontology,and building different templates for different requirements,this approach can quickly find candidate services with higher matching degree,to provide foundation for on demand service selection and customization.Finally,a case study is given to demonstrate validity of the approach.更多还原
