Paper Abstract
Schema Matching is one of key steps in GIS client database updating. In order to find semantically similar elements between schemas of master database and client database, an approach based on instance statistical similarity is presented. Different instance comparing technologies, such as correlation analysis, edit distance calculation, are used to determine the similarity of schema elements. Unlike other schema matching methods that only focus on attribute-level matching, our method adopts a hierarchical strategy to determine mapping relationship form two-level schema elements
including feature classes and attributes. Experimental result is also presented to demonstrate the viability of this
approach.
