| 摘 要： | 针对XML数据的半结构化特征,从XML的文本和结构特征上,结合BWT方法,来消除冗余数据。用实验说明对于压缩后文本查询的高效性。分析了当前结构连接的不足,提出了ESL方法,通过该方法,得到的结构索引比原始数据明显要小的多。提出了处理XML查询的一个模型,并对实现该模型作了初步的探讨。

| Abstract: | Aim at the semi-structured characteristics of XML data,and from the text and structure of XML,the article eliminates the redundant data combined with BWT method.Experiment shows the high efficiency of text query after compression.The paper also analyzes the current lack of structural connections,and puts forward the ESL method.With this method,the structure index gotten is significantly smaller than the original multi-data.A model for XML query processing is proposed,and preliminary discussion of implementation of the model is made. |
