Multi-strategy GML application schema matching approach

  • GML(geography markup language) application schema matching is a basic problem in the GML-based share of geography information. Combining the existing pattern matching algorithms and the characteristic of GML3.0 application schema, a multi-strategy GML application schema matching approach was proposed. Firstly, the input GML application schemas were transformed into the tree structure. The specific matching rules including linguistics and constraint were introduced which would help to compute the similarity between two elements, and then the two results were merged into element-level similarity. Secondly, the element-level similarity was modified by a structure-level matching algorithm based on similarity flooding theory. Finally, a mapping table of GML application schema elements was obtained. Experiment results show that the approach can effectively discovery the element similarity, and it can improve the matching result with a high degree of accuracy.
