科技文献检索方法分析一、引言科学技术的快速发展与普及，使得科技文献的数量与质量也在持续增长，如何高效检索到所需文献成为了研究人员必须掌握的技能。

本文就科技文献检索方法进行分析。

二、传统检索方法1.手工检索手工检索是最传统的检索方法，它主要通过人工阅读目录、索引、书目、图书馆目录等文献预设的文献信息载体进行查找。

由于人工检索需要耗费大量的时间和精力，因此在实际使用中存在诸多缺陷。

2.机械检索机械检索是指计算机在检索数据库系统中自动检索信息，同时根据检索的信息进行分类和组织的过程。

该方法的优点在于：它能够自动化地处理大量的文献信息，可有效解决传统手工检索无法解决的难题；但它也存在诸多缺陷：如建立检索系统耗费大量时间与精力，且前期建设需要投入大量资金。

三、现代检索方法1.全文搜索引擎检索全文检索是最直接的检索方式，通过搜索引擎（如Google scholar、百度学术、谷歌学术）输入关键词，并导出相关文献列表，是我们日常最常用的检索方式。

全文检索特别适合短文、论文、会议论文、科技新闻等简短性的文献检索。

2.基于语义的检索基于语义的检索是指通过对文献内容进行深层次的语义分析和处理，提升检索系统对查询的理解，并对匹配结果进行排序。

相比于传统检索方法，基于语义的检索更能精准地查找文献。

在实际检索中，我们可以通过专门的基于语义的检索引擎（如百度学术、谷歌学术，WoS）进行检索。

四、高效检索技巧目前各种检索方式都存在一定的缺陷，如何选择适合的检索方式，才能提升检索效率呢？以下几点是检索过程中应注意的技巧：1.确立清晰的检索目的和内容。

首先，在开始检索之前，需要明确检索的具体目的和内容，以便通过适当的关键词和检索方式，更加快速高效地获取到所需文献。

2.合理选择关键词。

关键词的选择是检索过程中非常重要的一步。

可以选择与自己研究领域相关的关键词，并且可以通过拆分关键词的方式提高检索的精确度。

例如：病毒性颠痫发作，可使用“病毒性”、“颠痫发作” 进行关键词拆分。

2013文献检索真题一、填空题（每空1分，共15分）1. 根据文献的载体形态，可将其分为__印刷型_ _、_声像型_、__缩微型_、_机读型_四种类型。

2. 维普数据库收录的妇产科学方面的核心期刊有5种。

3. 若某参考文献为：Dhanireddy KK, Xu H, Mannon RB, Hale DA, Kirk AD. The clinical application of monoclonal antibody therapies in renal transplantation. Expert Opin Emerg Drugs.2004 May;9(1):23-37.则该参考文献发表在Expert Opin Emerg Drugs杂志第9卷上。

4. 搜索引擎一般由搜索器、_索引器_、_检索器_三部分组成。

5. 在ScienceDirect数据库中，Applied Nursing Research期刊的ISSN号是_0897-1897_，最近的影响因子是__0.932_。

6. 中国优秀硕士论文数据中收录的浙江大学2012学位年度神经病学专业的硕士论文共有21篇，其中硕士生毛琳所写学位论文题名为：卒中后抑郁大鼠学习记忆障碍研究。

7. 作者袁秉祥发表在第八届海峡两岸心血管科学研讨会上的会议文献题名为《心血管药物相互作用与复方药品研发》，《EPO对实验性2型糖尿病大鼠糖代谢的影响》_。

二、单选题（每题1分，共5分）1. 下列属于一次文献的是（C）A. 文章草稿B. 目录C.公开出版的会议文献D. 词典2. 在数据库中，概念从小到大依次是：（B）A. 文档<记录<字段B. 字段<记录<文档C. 文档<字段<记录 D .字段<文档<记录3. 检索文献数据库时，下列哪种方法不能扩大检索范围(A)。

A. 主题词加权B. 用ORC. 用主题词扩展D. 采用截词4. SD数据库中若检索词A必须在检索词B之前出现，且中间最多间隔N个词，则检索式为（D）。

这是高等学校学生必须练好的本领，也是我国教育面向现代化、面向世界、面向未来的需要。

知识与情报往往记载在文献之中，因此高校学生必须善于检索与利用文献。

而文献检索课程正是这样一门以引导学生培养自学和独立研究能力、树立情报意识以及提高图书馆文献使用率等知识为教学课程，其重大意义不言而喻。

据调查走发现：现在的大学生甚至连毕业生的查找信息的方式很单一，一般就是上网用百度、谷歌等搜索引擎，很少有去图书馆查阅资料或者使用其它的查阅方式的。

这直接导致的就是他们创新精神较弱，分析间题、处理问题或提出有份量的见解能力较差。
