| 摘 要： | 与标准的方法XQuery查询语言不同,XML文档的关键字查询能使用户方便地访问XML数据,不必考虑数据复杂模式和掌握复杂查询描述语言。文章对关键字查询中索引技术进行研究,提出了一种基于Dewey编码的查询索引进行解决,以综合分析XML数据的值信息和结构信息,达到子树返回和路径返回的精确查询的目标。

| Abstract: | Keyword search enablesW eb users to easily access XML data without the need to learn a structured query language and to study complex data schemata.An index technique of keyword search was researched.A query index based on dewey code that can analyse the value and structure information ofXML was presented.The results ind icate that the technique can meet the precise de-mand such as subtree return and path return. |
