借鉴Web网页超链的思想,提出利用“数据服务超链”的抽象辅助用户显式地描述数据源之间隐含的关联关系,在此基础上提出基于超链的数据服务即时构造方法,使用户能在进行数据服务导航过程的同时对数据进行即时集成.为了辅助用户在数据服务即时构造过程中进行临机决策,以应对变化的需求,还讨论了一种数据服务超链推荐算法以帮助用户选择合适的数据服务超链.结合案例进行了分析评价及实验,结果表明,本文提出的方法能够有效地支持情景数据集成.
Enlightened by web page hyperlink,a novel abstraction "data service hyperlink" for linking and integrating data was proposed.With the help of "data service hyperlink",users can explicitly describe the relationship between data sources.Based on data service hyperlink,the approach to just-in-time data service construction was proposed to enable users integrate data while navigating data services.A data service hyperlink recommendation algorithm was also discussed to help users select proper data service hyperlink to deal with the temporary requirements.A case-study and some experiments how to build a situational data integration application based on data service hyperlink efficiently were presented.
