Web搜索引擎的智能搜索設計與實現(xiàn)
畢業(yè)論文
摘 要
Internet已經(jīng)成為目前世界上最大的系統(tǒng)資源庫，但是網(wǎng)上信息資源紛繁復雜，如何滿足人們對快速、準確而全面獲取信息的要求，已經(jīng)成為擺在人們面前的1大難題。搜索引擎億的出現(xiàn)可以幫助用戶在網(wǎng)絡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問題，如鏈接不成功或者根本就沒有頁面、內(nèi)容重復、分類不明確、搜索結果沒有記憶功能等。本系統(tǒng)使用Delphi設計和實現(xiàn)了1個信息搜索系統(tǒng)，目的就是為了解決此類問題，該系統(tǒng)不同與1般基于瀏覽器的搜索引擎，它使用智能代理技術(intelligent agent)，把搜索引擎移植到個人終端機上，方便用戶使用，并加上1些為用戶度身定制的搜索環(huán)境，幫助用戶進行快速搜索和自動搜索。該系統(tǒng)最大的特點是在本地機上實現(xiàn)搜索，不必打開瀏覽器，也不用登錄搜索網(wǎng)站，即可輕松獲得想要的信息。
關鍵詞：搜索引擎; 智能代理; 信息搜索; 本地終端
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.
Keywords: search design; intelligent agent; information search; local terminal
