| 摘 要： | 针对当前数据集成方法只能精确到属性级映射的缺陷,提出了基于数据元的数据集成方法。用数据元语义树对实体属性概念的内涵进行语义描述,使实体属性的语义能被计算机理解。然后通过语义计算实现精确到实例级的语义映射,从而完成数据集成。

| Abstract: | For the shortcomings of the attribute-level mapping in the current data integration approach,a new data integration approach based on data elements is presented,which uses semantic tree of data elements to describe the connotation of the properties's concept,and the semantic of the properties can be understood by computer,and then the instance-level semantic mapping can be realized by semantic computation,so that the data integration can be completed. |
