【摘要】 该文介绍了一个应用于结构化文本的检索系统的设计和实现。根据结构化文本的自身特点,提出了文本层次划分的思想,通过层次划分,文本被切分成有结构信息和有独立思想内容的文本单元。在此基础上,对检索词实现结构化索引,同时采用层次匹配嵌套查询的方法来实现用户自然语言的提问查询。用户查询处理中还综合运用了查询结果优化、相似查询、二次查询及反馈评分的技术。更多还原

【Abstract】 The design and implementation of Structured Text Retrieval System is introduced in this paper.According to structured text’s characteristic,hierarchical division approach is put forward in text division.As a result,text is divided into text unit with structure and meanings.The ratio of accuracy of query is promoted by using structured indexing techniques and hierarchical matching algorithm,together with the techniques used in query,such as result optimization,similar match,second query and users’ evaluating.更多还原
