摘要： 旨在建立一个具有自学习功能的概念网络，利用它可识别知识的多种不同表现形式（即知识表现形式的不确定性），并在此基础上，建立一个搜索引擎，根据这个概念网动态优化搜索条件，进行基于概念的搜索，从而充分提高搜索的查全性和查准性。

Abstract: This article is aimed to construct a concept network which can adapt itself according to retrieved information, and with which the knowledge can be identified from its different representations.On this basis, we'll bulid a search engine, which can optimize the query items dynamically and make search based on concept, so to improve the accuracy and the extension at the same time.
