| 摘 要： | 首先分析了传统信息检索技术存在的语义匮乏的缺点,然后对语义检索的基本原理、本体知识、语义信息系统四个关键模块进行了说明,给出一种新的本体构建方法,在此基础之上提出了基于本体信息检索系统的体系框架,并且描述了系统原型的设计思想和检索流程,最后通过一个试验系统平台对系统模型进行验证。实验结果表明,在和传统检索系统的对比中,本系统具有扩充检索词的内涵和外延的强大功能,极大提高了检索的查全率和查准率等性能和优越性。

| Abstract: | This paper makes first an analysis of the shortcoming of semantic meaning lack existed in traditional information retrieval technique,then detailed explanation is given to the basic principles of the semantic retrieve,the ontological knowledge,and the four key modules of semantic information system,etc..A new approach of ontology is employed to construct a systematic frame with ontological information retrieval system as the base.The design thought and the retrieval process of the systematic prototype are also depicted.In the end,the systematic model is validated through a platform of trial system.The result shows that when contrasted with traditional retrieval system,this system has a strong function in extending the connotation and denotation of the search words.So,it has the superiority in enhancing greatly the precision and recall. |
