面向压缩XML文档的数据快速过滤与片断分发方法

Efficient Filtering and Fragment Dissemination of Compressed XML Documents

XML数据的过滤和分发是XML应用领域的研究热点之一。为了提高XML文档的传输效率,有必要进行压缩。本文提出一种应用于压缩XML文档的过滤和片断分发方法。实验表明,这种方法既保持了压缩文档的传输效率优势,又滤掉了非查询目标数据,提高了分发中心的匹配/分发处理效率。

The filtering and dissemination of XML documents is one of the most popular research areas of XML applications. In order to improve the transfer efficiency of XML documents, compression should be used. But few of the filte- ring and dissemination algorithms of compressed XML documents have been proposed. We introduce a new method of filtering and dissemination of compressed XML document, which can efficiently filter and accurately disseminate the fragments to end users. Experiments show that our method is time and space efficient.
