基于实例的GIS数据库模式匹配方法
An Instance-Based Approach for Schema Matching Between GIS Databases
-
摘要: 针对空间数据库的特点,提出了一种改进的基于实例的层次式模式匹配方法,并解决了实体对应关系的自动建立、要素类相似性计算、属性相似性计算等问题。最后,通过实验验证了该方法的有效性。Abstract: According to the characteristic of GIS database,an improved instance-based hierarchical approach to schema matching is proposed,some key issues within which are also be resolved such as automatic identification of shared entities,similarity computation between feature classes,attribute similarity computation,etc.Finally,experimental result is present to validate the efficiency of this approach.
