| 摘 要： | 针对普通用户发出的面向XML文档的自然语言模糊查询,分析了模糊内容和结构检索(VCAS)的影响因素,充分利用预设答案结点的逻辑意义完整性,结合模糊抽取的查询表达式给出了如何找到模糊内容检索的最佳查找粒度.在此基础上,设计了VCAS检索的结果相关性排序模型,最后通过实验从不同角度对模型进行了验证.

| Abstract: | The properties of vague retrieval are studied over XML documents issued by general users in natural language.Then,utilized logical integrity of answer node,the factors of XML vague retrieval are analyzed about relaxation on structure and content,and the way is proposed about how to find the best query granularity from the query expression extracted from natural language vague query and search paths in XML tree.Furthermore,a ranking model is designed to handle these new features;finally the confirmation is carried on through the experiment to the model. |

| Keywords: | XML retrieval answer node vague content and structure result ranking |
