| 摘 要： | 近年来,XML已成为信息表示、交换和发布的标准,因此,XML数据查询已成数据库(DB)和信息检索(IR)领域广发研究的问题。XML通常被视为一个标签树,常用的方法是近似查询。由于在用户查询通常有一定的关系约束出现,在分析了用户查询对XML元素和值关系约束之后,本文提出了使用关系约束近似提取XML元素的方法

| Abstract: | In last years,XML has become the standard for information representation,exchange,and publish. Therefore,querying XML data is a well-explored topic in both Database (DB) and Information Retrieval (IR) fields,which shows proximity search well suited to XML documents,often modeled as a labeled trees. Based on the observations that there are some relationship restrictions in user's query,this paper first analysis query restrictions on elements and their values,and then proposes to approximately extract XML ele... |
