【摘要】 随着Internet的飞速发展，Internet的应用深入到各行各业，Internet上的信息变得繁杂，信息的查找与获取也就变得越来越困难，Web上的信息检索工具一搜索引擎正面临着极大的挑战。 本文从研究信息检索以及用于信息检索的搜索引擎的现状入手，指出了当前搜索引擎面临的挑战与关键问题，对智能检索技术—这一代表信息检索技术未来发展的技术进行了深入的研究。在分析当前智能搜索引擎的特征和技术的基础上，指出了智能搜索引擎的概念检索新思路。 智能信息检索以概念检索为主，而不是简单的关键词匹配。本文介绍了概念检索的基本原理和特征；研究概念语义网络的构建以及基于知识库概念检索的实现原理；根据智能搜索引擎的设计思想，给出了一个新的智能搜索引擎框架结构；通过增加领域知识库和用户知识库与增强用户接口界面的功能，使搜索引擎真正达到智能化效果。更多还原

【Abstract】 With the development of Internet, Internet has been thoroughly applied in all trades and professions. Information in Internet grows miscellaneous and Internet users find that it is becoming more and more difficult to search and gain information available. The search engines, serving as the retrieval tool of internet information, are facing extreme challenge.This article beginning with information search and search engine serving as the retrieval tool of Internet information, it points out search engines are facing challenge and pivotal question. The paper deeply studies the intelligent information search technology which represents intending development of information search and analyzes some characteristics and technique of intelligence retrieval engine. It points out that the intelligent information retrieval system is characterized concept retrieval.Intelligent information retrieval system is characterized not by simple key word match, but concept retrieval as its core. The basic principle and properties of concept retrieval have been introduced in the paper. Then, the paper introduces the construct of concept semantic network and the principle of development of Concept Retrieval based on knowledge base. According to the design thought , a new system structure to search engine that enlarges the domain knowledge-base and users knowledge-base and enhances the function of user interface has been put forward in the paper. It also indicates that the veritable intellectualization of search engine must be supported by knowledge base.更多还原
