吉大17年3月课程考试《文献检索》离线作业考核要求答案(可直接上传)

简述题(每小题20分,共100分) 一、文献检索与日常护理工作的关系。 答:文献检索,是指将信息按一定的方式组织和存储起来,并根据信息用户的需要找出有关的信息过程,所以它的全称又叫“信息的存储与检索,这是广义的信息检索。狭义的信息检索则仅指该过程的后半部分,即从信息集合中找出所需要的信息的过程,相当于人们通常所说的信息查寻。但文献检索不能一层不变,知识经济更新的速度在不断的加快加强。在文献检索的时候要做好日常的护理工作。随时更新检索的内容。适当的检索功能能减少日常护理的工作难度,而日常的护理工作可使文献检索更具条理化,他们之间应该是相互依附的关系,相辅相成。 二、中目》(医)有几条检索途径,各自的路径是什么? 答:检索途径:分类途径、主题途径、著者途径和其他途径。 1. 分类途径。分类途径是指按照文献资料所属学科类别进行检索的途径,它所依据的是检索工具中的分类索引。分类途径检索文献关键在于正确理解检索工具的分类表,将待查项目划分到相应的类目中去。一些检索工具如《中文科技资料目录》是按分类编排的,可以按照分类进行查找。 2. 主题途径。主题途径是指通过文献资料的内容主题进行检索的途径,它依据的是各种主题索引或关键词索引,检索者只要根据项目确定检索词,主题词或关键词,便可以实施检索。主题途径检索文献关键在于分析项目、提炼主题概念,运用词语来表达主题概念。主题途径是一种主要的检索途径。 3. 著者途径。著者途径是指根据已知文献著者来查找文献的途径,它依据的是著者索引,包括个人著者索引和机关团体索引。 4. 其他途径。其他途径包括利用检索工具的各种专用索引来检索的途径。专用索引的种类很多,常见的有各种号码索引如专利号、入藏号、报告号等,专用符号代码索引如元素符号、分子式、结构式等,专用名词术语索引如地名、机构名、商品名、生物属名等。 三、用于机检的逻辑运算符有几种,各自的功能是什么? 答:用于机检的逻辑运算符:与、或、非。逻辑与的功能:它是一种用于交叉概念和限定关系的组配,它可以缩小检索范围,有利于提高查准率。凡是用and的检索式,其两侧的检索词必须同时出现在同一条记录中,该记录才算命中。逻辑或得功能:是一种用于并列关系的

吉大药学年《文献检索》离线作业及答案

一、什么是文献?文献按其出版形式划分为哪几个类型?(10分)答:文献:记录信息和知识的载体,是人类从事科学实验和生产实践的智慧结晶,是人类精神财富的重要组成部分。 文献按其出版形式划分为1图书2期刊3技术报告4会议报告5专利文献6标准文献7学位论文8政府出版物9档案资料。 二、什么是数据库?按其内容可以分为那几个类型?(15分) 答:数据库:是以特定的组织方式将相互的数据集合存储的总汇。 按国际上通用的分类方法,数据库分为以下三大类: 1、参考数据库(Reference databases),是能指引用户到另一信息源获取原文或其他细节的数据库; 2、源数据库(Source databases),指能直接提供所需原始资料或具体数据的数据库。; 3、混合型数据库(Mixed databases),能同时存贮多种类型数据的数据库。 三、什么是核心期刊?(15分) 答:核心期刊是期刊中学术水平较高的刊物,是我国学术评价体系的一个重要组成部分。它主要体现在对科研工作者学术水平的衡量方面,如在相当一批教学科研单位申请高级职称、取得博士论文答辩资格、申报科研项目、科研机构或高等院校学术水平评估等,都需要在在核心期刊上发表一篇或若干篇论文。 四、简述信息检索的基本步骤?(15分) 答:(1)明确查找目的与要求; (2)选择检索工具; (3)确定检索途径和方法; (4)根据文献线索,查阅原始文献。 五、检索中常用的逻辑运算符有那几个?其含义如何?(15分) 答:常用的有三种:逻辑与(and) 、逻辑或(or)和逻辑非(not) 含义见下表:

六、掌握文献常用的方法是什么?(15分) 答:1. 直接法 直接利用检索工具(系统)检索文献信息的方法,这是文献检索中最常用的一种方法。它又分为顺查法、倒查法和抽查法。 (1)顺查法 按照时间的顺序,由远及近地利用检索系统进行文献信息检索的方法。这种方法能收集到某一课题的系统文献,它适用于较大课题的文献检索。例如,已知某课题的起始年代,现在需要了解其发展的全过程,就可以用顺查法从最初的年代开始,逐渐向近期查找。 (2)倒查法 倒查法是由近及远,从新到旧,逆着时间的顺序利用检索工具进行文献检索的方法。此法的重点是放在近期文献上。使用这种方法可以最快地获得最新资料。 (3)抽查法 抽查法是指针对项目的特点,选择有关该项目的文献信息最可能出现或最多出现的时间段,利用检索工具进行重点检索的方法。 2. 追溯法 不利用一般的检索工具,而是利用已经掌握的文献末尾所列的参考文献,进行逐一地追溯查找“引文”的一种最简便的扩大信息来源的方法。它还可以从查到的“引文”中再追溯查找“引文”,像滚雪球一样,依据文献间的引用关系,获得越来越多的相关文献。 3. 综合法 综合法又称为循环法,它是把上述两种方法加以综合运用的方法。综合法既要利用检索工具进行常规检索,又要利用文献后所附参考文献进行追溯检索,分期分段地交替使用这两种方法。即先利用检索工具(系统)检到一批文献,再以这些文献末尾的参考目录为线索进行查找,如此循环进行,直到满足要求时为止。

文献检索作业答案带图(1)

1.简述文献的构成。 答:现代文献由四要素构成:文献信息、文献载体、符号系统和记录方式。 2.简述医学文献的特点。 答:数量庞大、载体多样化、多文种化、学科交叉出版分散、知识信息更新加快、交流传播速度加快、电子化发展趋势。 3.简述文献检索的概念和类型。 答:概念:广义的文献检索包括信息的存储和检索两个过程,是指将文献按照一定方式集中组织和存储起来,并按照文献用户需求查找出有关文献或文献中包含的信息内容的过程。 狭义的信息检索即从检索工具或检索系统中,通过一定的检索途径或检索方式查找出需要的信息的过程。 类型:①按照检出结果的形式划分:书目检索、全文检索、引文检索。 ②从情报检索角度划分:文献检索、数据检索、事实检索。 ③按照线索手段划分:手工检索、计算机检索。 4.简述文献检索系统的评价因素。 答:报道信息的准确性、报道信息的及时性、索引体系的完善程度、对信息标引的深度、查全率和查准率。 5.什么事查全率和查准率,二者之间有何关系? 答:查全率(R)和查准率(P)是检索系统最为流行和重要的两个性能和效果评价指标。 R=检出的相关信息量/检索工具中相关信息总量X100% P=检出的相关信息量/检出的信息总量X100% 两者之间存在互逆关系,即如果检索工具的查全率较高,则其查准率将相对下降;反之查准率高,则查全率低;而且查全率和查准率只能相对提高,二者永远不可能同时达到100%。 6.试述文献信息的类型。

答:①按文献信息表现形式划分:文字型、视频型、音频型、数字型 ②按文献信息的出版类型划分:图书、期刊、政府出版物、科技报告、专利文献、会议文献、学位论文、标准文献、产品样本说明书、技术档案 ③按文献信息的载体形式划分:印刷型、缩微型、声像型、电子型 ④按文献信息的加工程度划分: ⑴零次文献信息:书信、手稿、实验数据、观察记录、笔记、内部档案等。特点:内容新颖,但不成熟,难以查询。 ⑵一次文献信息:期刊论文、专利说明书、会议论文、学位论文、科技报告等。特点:内容新颖、详尽,因而是文献信息的最主要来源和检索对象,但其量大、分散而无序,对其查找与利用带来不便。 ⑶二次文献信息: 目录、索引和文摘等。特点:报道性和检索性,主要作用是提供查找文献信息的线索,故又称为检索工具。 ⑷三次文献信息:综述、进展、年鉴和百科全书等。 7.试述电子文献资源的概念与特点。 答:电子文献资源是以电子数据的形式,把文字、声音、图像、视频、等多种形式的文献存储在光、磁等非印刷纸质的载体中,以电信号、光信号的形式传播,并通过网络通信、计算机或终端和其他外部设备等方式再表现出来的一种新型文献资源。 特点:1.存储介质和传播形式的改变 2.信息的表现形式多样化 3.文献资源类型多样化 4.多层次的信息服务功能 5.更新速度快、时效性强 6.具备检索系统或功能 7.检索访问不受时空限制 8.试述医学电子文献资源的类型。
