Web搜索引擎的智能搜索设计与实现

摘　要
Internet已经成为目前世界上最大的系统资源库，但是网上信息资源纷繁复杂，如何满足人们对快速、准确而全面获取信息的要求，已经成为摆在人们面前的`1大难题。搜索引擎亿的出现可以帮助用户在网络上方便地查找到自己需要地信息。但目前的搜索引擎仍存在不少问题，如链接不成功或者根本就没有页面、内容重复、分类不明确、搜索结果没有记忆功能等。本系统使用Delphi设计和实现了1个信息搜索系统，目的就是为了解决此类问题，该系统不同与1般基于浏览器的搜索引擎，它使用智能代理技术(intelligent agent)，把搜索引擎移植到个人终端机上，方便用户使用，并加上1些为用户度身定制的搜索环境，帮助用户进行快速搜索和自动搜索。该系统最大的特点是在本地机上实现搜索，不必打开浏览器，也不用登录搜索网站，即可轻松获得想要的信息。

Abstract
Internet has become the worlds largest resource base of the system, but online information resources complicated, so how to meet people’s request of fast, accurate and comprehensive access to information in front of the people have become a major problem. The emergence of search engines in networks can help users to easily find the information they needed to. But current search engines are still have many issues, such as links unsuccessful or no screens, content duplication, classification is not clear, search results without memory functions. I used the Delphi to design and to achieve an information search system, which was intended to address such issues. The system is different from the general search engine based on the browser, which use smart agent technology (intelligent agents) to transplant search engines to individual terminals, for user-friendly, plus some tailor-customized to the users search environment to help users search for rapid and automatic search. The greatest feature of the system is to achieve search in the local machine without opening the browser, do not have posted Pathfinder, and easy access to information.
