摘　　要：基于数据服务的互联网数据即时集成利用数据服务封装互联网上的数据源,用户根据个性化的需求即时组合服务,集成不同数据源中的数据.数据源服务化后,数据源间的数据关联需要通过服务间的关联实现.由于没有承载数据服务间数据关联的载体,已建立的关联无法得到复用,用户每次集成需手工选择和组合服务,导致组合过程易出错且效率低.提出一种数据服务超链模型,通过一个服务的输出参数与另一个服务的输入输出参数间的关联,表达两个服务之间存在的单向的数据关联;给出一种数据服务超链建模方法,重点实现基于组合案例的服务超链自动建模.通过与其他服务关联模型比较,数据服务超链可全面表达服务间的数据关联;通过实验验证了建模方法的有效性.Instant Internet data integration based on data services utilizes data services to encapsulate data sources on Internet, and users integrate the data of different data sources through composing services instantly according to their personalized requirements. After services encapsulation, existing data correlations of different data sources need to be implemented through correlations of data services. Since there is no carrier for data correlations of data services,and correlations created can＇t be reused, users have to choose and com- pose data services manually each time. Consequently, the integration process is error-prone and inefficient. This paper presents the data service hyperlink model. Through the correlations of one serviee＇s output parameters and another service＇s input and output parame- ters, unidirectional data correlations of two data services are described. In addition, the data service hyperlinks modeling method is pro- posed. In this method, automatic modeling according to services composition cases is realized. Compared to other services correlation models,data service hyperlink presents data correlations of services comprehensively. The effectiveness of the proposed modeling method is verified through experiments.
