WEB搜索引擎

畢業(yè)論文

摘要
隨著互聯(lián)網(wǎng)的迅速發(fā)展，網(wǎng)絡(luò)規(guī)模不斷擴(kuò)大，信息儲(chǔ)量急劇增長(zhǎng)，搜索引擎技術(shù)越來(lái)越得到廣泛地使用。
本文通過(guò)對(duì)各種通用搜索引擎的關(guān)鍵技術(shù)進(jìn)行研究，完成了對(duì)通用WEB搜索引擎的設(shè)計(jì)與實(shí)現(xiàn)。搜索引擎系統(tǒng)包括3個(gè)功能模塊：網(wǎng)頁(yè)獲取模塊，數(shù)據(jù)存儲(chǔ)模塊和檢索模塊。本人在課題組中主要承擔(dān)工作有：系統(tǒng)整體設(shè)計(jì)、數(shù)據(jù)庫(kù)的設(shè)計(jì)實(shí)現(xiàn)以及中文分詞系統(tǒng)的設(shè)計(jì)實(shí)現(xiàn)。
本系統(tǒng)的整體設(shè)計(jì)突出操作簡(jiǎn)便、功能強(qiáng)大、人性化設(shè)置、并行處理可移植等特點(diǎn)，其中中文分詞，各模塊的存儲(chǔ)流程是系統(tǒng)的設(shè)計(jì)亮點(diǎn)。本文中對(duì)搜索引擎的各種技術(shù)算法進(jìn)行了介紹，而且根據(jù)系統(tǒng)的需要進(jìn)行了各功能模塊的設(shè)計(jì)。數(shù)據(jù)庫(kù)設(shè)計(jì)的特點(diǎn)是：大容量存儲(chǔ)、高效檢索和簡(jiǎn)單查詢。索引數(shù)據(jù)庫(kù)以頁(yè)面信息表和詞庫(kù)表為核心，通過(guò)對(duì)詞創(chuàng)建索引以提高檢索效率；中文分詞系統(tǒng)采用VC++平臺(tái)開發(fā)，實(shí)現(xiàn)對(duì)中英文句子的分割，使其分為單獨(dú)的詞或詞組。
關(guān)鍵詞:搜索引擎；WEB搜索；中文分詞；索引數(shù)據(jù)庫(kù)；排序
 
Abstract
With the rapid development of the internet, the constant expansion of the network size, the run-up growing of the information storage, the technology of the search engine is becoming more and more popular.
The article accomplish the design and realization of the general WEB search engine through the studying of all kinds of the general search engine. The search engine system includes three functions modules. They are Homepage gain module, data storage module and retrieval module. My main duty in this topic research is overall System design, database design realization, Chinese participle system design realization.
The prominent point in this overall system is that operation is simple, the function is formidable, the human nature establishment, the parallel processing may transplant and so on, especially the Chinese participle and each memory operation module. The article does not only introduce all kinds of technical algorithm in the search engine, but design each function module according to the need of the system. The database design characteristic is: Large capacity memory, highly effective retrieval, simple inquiry. The index database takes the page information table and the word storehouse table as a core, enhancing the searches efficiency through establishing the words index. Chinese participle system uses the VC++ platform exploitation, realization to the Chinese and English sentence division, causes it to divide into the independent word or the phrase.
Keywords: WEB search; Chinese participle; Index database; Arranges
