WEB搜索引擎
畢業論文
摘要
隨著互聯網的迅速發展，網絡規模不斷擴大，信息儲量急劇增長，搜索引擎技術越來越得到廣泛地使用。
本文通過對各種通用搜索引擎的關鍵技術進行研究，完成了對通用WEB搜索引擎的設計與實現。搜索引擎系統包括3個功能模塊：網頁獲取模塊，數據存儲模塊和檢索模塊。本人在課題組中主要承擔工作有：系統整體設計、數據庫的設計實現以及中文分詞系統的設計實現。
本系統的整體設計突出操作簡便、功能強大、人性化設置、并行處理可移植等特點，其中中文分詞，各模塊的存儲流程是系統的設計亮點。本文中對搜索引擎的各種技術算法進行了介紹，而且根據系統的需要進行了各功能模塊的設計。數據庫設計的特點是：大容量存儲、高效檢索和簡單查詢。索引數據庫以頁面信息表和詞庫表為核心，通過對詞創建索引以提高檢索效率；中文分詞系統采用VC++平臺開發，實現對中英文句子的分割，使其分為單獨的詞或詞組。
關鍵詞:搜索引擎；WEB搜索；中文分詞；索引數據庫；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
