thesaurus

These might actually reduce the size of the database since it would store only canonical forms and not variants , but this would come at the cost of external thesauri and rule - patterns for word transformations
这种方法的确能减小数据库大小，因为只需存储正则形式而不必存储变化形式，但词语转换需要消耗外部类属词典和变化规则形态。
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。
