according to such an idea, we propose a new retrieval method that combines xpath and vector space model, named as the vector retrieval model based on xpath . secondly, we make full use of the hierarchical architecture of xml data, and analyze the structure of every document to construct a structure thesaurus, which is designed to navigate the user query and to eliminate the structural conflict 根据这一思想,作者提出了将xpath语言与传统的向量空间模型相结合,实现基于简单xpath路径的向量检索算法来实现对xml文档的检索。充分利用xml文档分类层次体系结构的特点,对于每篇xml文档分析其文档结构,并采用聚类学习算法形成文档结构类属词典,从而实现xml文档查询的导航机制和消除文档结构的异构性。
