有效生成XML键的智能拓展算法

Intelligent extending to efficiently deriving XML keys

提出一个针对XML文档数据有效生成XML键的智能拓展算法。该算法利用事先定义的标识键文件生成完备的键集,同时对该标识键文件动态更新。理论分析和仿真实验表明,该算法获得的键集有效性较高,对于大规模XML测试数据其优越性尤为明显。

This paper proposes an algorithm for intelligent extending to efficiently deriving XML keys based on XML document.The self-contained key set is obtained by utilizing LabelKey file defined before,and the file is dynamically updated at the same time.Theoretical analysis and experiment show the algorithm has a quite high validity of deriving key set,and the superiority is very obvious to the cosmically XML data samples.
