JCR 5年期影响因子实证分析   总被引：1，自引：0，他引：1  

王娟  郑春厚 《图书情报工作》2012,56(4):143-147

使用期刊引证报告（JCR）中高分子科学学科1999-2009 年间的49种期刊数据,从多种角度对5年期刊影响因子(IF5)的性质进行分析。结果显示,IF5不仅能反映多数期刊的被引高峰期,而且能较好地反映出期刊的平均被引水平,体现期刊影响因子概念的本质。最后,将期刊的5年期影响因子与基于被引半衰期的响因子作对比分析,发现IF5本身隐含着期刊论文的被引规律。  相似文献

Are the authors of highly cited articles also the most productive ones?     

《Journal of Informetrics》2014,8(1):89-97

Ever more frequently, governments have decided to implement policy measures intended to foster and reward excellence in scientific research. This is in fact the intended purpose of national research assessment exercises. These are typically based on the analysis of the quality of the best research products; however, a different approach to analysis and intervention is based on the measure of productivity of the individual scientists, meaning the overall impact of their entire scientific production over the period under observation. This work analyzes the convergence of the two approaches, asking if and to what measure the most productive scientists achieve highly cited articles; or vice versa, what share of highly cited articles is achieved by scientists that are “non-top” for productivity. To do this we use bibliometric indicators, applied to the 2004–2008 publications authored by academics of Italian universities and indexed in the Web of Science.  相似文献   

用于引书识别的引书引用模式研究     

衡中青  侯汉清 《图书情报工作》2009,53(15):142-141

现代信息技术飞速发展,为古籍引书计算机识别提供了可能性。本研究的目的是研究古籍引书的引用模式,进而探讨模式识别方法在引书识别中的应用。具体方法是以明、清及民国时期广东地方志中有关物产门目资料（《广东方志物产》）为语料,抽取所有引书的引用模式（引书名称及其表达方式）,分别对引书名称模式和引用表达方式进行研究。  相似文献

体裁、社会效应与学术竞争力——图书情报学科高被引论文内容结构考察     

陶俊 《图书情报工作》2016,60(1):56-65

[目的/意义]学术竞争力被普遍认为是衡量学科可持续发展的关键要素;通过图书情报学(简称"图情")高被引论文的内容结构特征阐释图情学术竞争力不足的影响因素并揭示其成因。[方法/过程]融合社会分层理论、市场效率理论和资源基础理论提出学术竞争力模型,构建"体裁-学术规范-社会效应"内容分析框架,利用中国知网全文数据库图情重点期刊2009-2013年80篇高被引论文、6552条引文开展内容分析。[结果/结论]高被引论文之报导型、基础型、应用型和综述型的体裁分布依次为78.8%、3.75%、10%和7.5%,且报导型以图书馆职业研究为主;高被引论文职业实践效应明显,基础社会效应相对不足。上述发现表明,图情学科学术竞争力不足跟论文的体裁结构和社会效应水平紧密相关,职业化是导致学术竞争力不足的根源。因此,就教育层面而言,推进学科转型是一条必由之路。  相似文献   

A Bibliometric Analysis of High Impact Research in the Middle East Using Champion Works     

Zeynep Ceren Akyüz  Ricardo Aleixo Correia 《International Information and Library Review》2017,49(1):11-18

Increasing political and financial support for scientific research in the Middle East requires academic and research communities in the region to demonstrate the visibility and impact of their scientific output. However, for countries with smaller scientific communities or lack of detailed information on their scientific production, the use of common metrics of scientific impact (e.g., number of papers, impact factor, h-index, etc.) may fail to reveal their true ability to produce high quality research, and thus guarantee the wanted societal support. In such cases, identifying and highlighting outstanding papers produced by national institutions or scientists may be another way to demonstrate scientific capacity and impact. In this context, this work aims to provide an overview of champion works (papers that have received over 1,000 citations) produced by Middle East countries. This analysis focuses on science, medicine, and technology papers featured in the Science Citation Index Expanded of Web of Science. The authors identified 213 champion works authored by Middle East scientists published since the 1970s. Israel is currently the leading nation in the Middle East in terms of published champion works, but at least one such work was identified for the majority of countries in the region. Middle East champion works were published on a diverse range of subject categories and often featured in the top journals worldwide (e.g., Science, Nature, etc.). The top institutions in the Middle East authoring champion works and their leading collaborating countries worldwide are listed, and the role of international scientific collaborations in achieving these highly cited papers is highlighted.  相似文献   

An Analysis Based on Citespace III Knowledge Maps of Chinese Vocational Education Research     

Yan Guangfen  Zhang Dongke 《Chinese Education & Society》2017,50(5-6):499-519

Abstract

As a strategic focus of talent cultivation in the new period, in recent years China’s vocational education practice has seen “leapfrog” style development. A systematic look at the current state of Chinese vocational education research and exploration of its core research institutions, most frequently cited works, research “hot topics,” and leading research is clearly needed and meaningful, and the method of using knowledge maps based on knowledge metrics provides an effective path to resolving this. Knowledge map software CiteSpace III was used to obtain quantitative statistics on works related to vocational education recorded in the Chinese Social Sciences Citation Index database and to explore the date, distribution by journal, and characteristics of the works; draw institutional cooperation maps; examine the core research institutions and their influence; draw publication citation maps; reveal most frequently cited works and their characteristics; draw key word co-occurrence maps; and explore the distribution of research hot topics and leading research.  相似文献
