摘要
现有的图书检索方法多是对馆藏图书进行编目、分类、标注等处理后形成书目数据库,用户根据书名、作者和出版社等信息来检索图书.这种方式不能满足用户根据任意关键词来检索图书的需求,效率较低.全文检索是基于倒排索引技术对文本中的所有词组和关键词进行索引,支持快速检索到文本中任何一个单词和关键词.若将全文检索技术应用于图书检索中,可使用户根据任意关键词检索图书,可根据检索量和用户习惯推荐热门图书.文章介绍了如何在图书检索过程中应用全文检索技术,分析了全文检索引擎选择、图书文本解析、图书文本分词、图书索引设计、图书文档提交等主要过程,并给出了全文检索技术的最终实现效果,以期对提升图书检索系统的易用性提供一定借鉴.
Abstract
The existing book retrieval methods mainly involve cataloging,classifying,and labeling books in the collection to form a bibliographic database,where users retrieve books based on informa-tion such as title,author,and publishing house.This approach cannot meet the user's needs for re-trieving books based on any keywords,and is less efficient.Full-text retrieval is an information tech-nology based on inverted indexing technology,which can index all phrases and keywords in the text and support quick retrieval of any word and keyword in the text.If full-text search technology is ap-plied to book retrieval,users can search for books based on any keyword,and recommend popular books based on search volume and user habits.The article will explore how to apply full-text retrieval technology in the process of book retrieval,and analyze the main processes of full-text search engines choice,book text parsing,book text segmentation,book index design,and book document submis-sion.The final implementation effect of full-text retrieval technology is also presented to provide some reference for improving the usability of book retrieval systems.
