【摘要】 设计并实现了基于范例推理的数据集成系统CBRDI,能够通过积累的领域知识即范例进行有效的数据集成操作。CBRDI采用框架网络表示范例,并通过聚类方法对源范例进行组织和索引,提高了范例搜索的效率。CBRDI系统实现简单,并具有较强的自学习的能力,推理效率高。更多还原

【Abstract】 Data integration is one of important data pretreatment steps in Knowledge Discovery in Databases(KDD).The paper presents a novel case-based reasoning method for data integration(CBRDI )that can effectively work by accumu-lating domain knowledge.CBRDI supports access to a variety of databases system and utilizes both schema information and data contents to design its case base.Furthermore,CBRDI makes use of clustering technology to index cases base.It discusses the effectiveness of CBRDI.更多还原
