社会科学类中文电子图书数据库馆藏学术性书目对比分析 总被引：1，自引：0，他引：1
以《中国哲社学术图书基本书目(1995-2005)》收录的政法类图书书目为标准书目,以上海地区本科以上高校图书馆馆藏中文图书数据库为测评对象,测定超星数字图书馆和方正Apabi数字图书馆(含教参全文数据库)所收录的电子图书的质量。统计分析两库标准书目图书入藏率,结果表明,总体上超星数字图书馆入选标准书目的图书多于方正Apabi数字图书馆,但2004年以后,方正Apabi数字图书馆入选图书超出了超星数字图书馆,并且两库学术性图书馆藏不完全同质,两库叠加学术性图书入藏种类的增加超过重复。 相似文献

Review papers tend to be cited more frequently than regular research articles. This fact, together with the continuous increase of the share of reviews in scientific literature, can have important consequences for the measurement of individuals’ research output, usually based on citation analysis. However, studies evaluating the differences in citations of review papers compared to original research articles are almost non-existing in the literature. This paper presents a thorough analysis of the overcitation and overrepresentation of review papers in the most cited papers of the 35 largest subject categories in Science Citation Index-Expanded. Results indicate the average citations received by reviews depends largely on the research area considered, varying from 1.34 to 6.74 times the citations received by original research articles (average value is 2.95). Correlated with this overcitation, there is an important overrepresentation of reviews in the most cited papers, this overrepresentation being greater when the most highly cited papers are considered, i.e. 0.05% and 0.1% most cited papers, where the share of reviews have increased from 16 to 18% in 1990 to around 40% in 2010. Interestingly, the overcitation and overrepresentation in the most cited papers is more important in the areas with the lowest shares of reviews in total publications. 相似文献

Dimensions is a partly free scholarly database launched by Digital Science in January 2018. Dimensions includes journal articles and citation counts, making it a potential new source of impact data. This article explores the value of Dimensions from an impact assessment perspective with an examination of Food Science research 2008–2018 and a random sample of 10,000 Scopus articles from 2012. The results include high correlations between citation counts from Scopus and Dimensions (0.96 by narrow field in 2012) as well as similar average counts. Almost all Scopus articles with DOIs were found in Dimensions (97% in 2012). Thus, the scholarly database component of Dimensions seems to be a plausible alternative to Scopus and the Web of Science for general citation analyses and for citation data in support of some types of research evaluations. 相似文献

2008-2013年中外科技期刊载文与引证指标分析 总被引：1，自引：0，他引：1
基于2008-2013年Thomson Reuters发布的Journal Citation Reports (JCR)及中国科学技术信息研究所发布的《中国科技期刊引证报告》(CJCR),比较分析中外科技期刊载文量、总被引频次、影响因子、即年指标等各主要文献计量指标的变化.结果显示,我国被SCI收录期刊的数量和影响力指标近年来总体上呈上升态势,但年平均载文量却稍有下降,以中文期刊为主的CJCR收录期刊数量和年平均载文量均呈停滞增长甚至下降的趋势.这可能表明我国科技期刊的稿源竞争力有所下降. 相似文献

Multidisciplinary cooperation is now common in research since social issues inevitably involve multiple disciplines. In research articles, reference information, especially citation content, is an important representation of communication among different disciplines. Analyzing the distribution characteristics of references from different disciplines in research articles is basic to detecting the sources of referred information and identifying contributions of different disciplines. This work takes articles in PLoS as the data and characterizes the references from different disciplines based on Citation Content Analysis (CCA). First, we download 210,334 full-text articles from PLoS and collect the information of the in-text citations. Then, we identify the discipline of each reference in these academic articles. To characterize the distribution of these references, we analyze three characteristics, namely, the number of citations, the average cited intensity and the average citation length. Finally, we conclude that the distributions of references from different disciplines are significantly different. Although most references come from Natural Science, Humanities and Social Sciences play important roles in the Introduction and Background sections of the articles. Basic disciplines, such as Mathematics, mainly provide research methods in the articles in PLoS. Citations mentioned in the Results and Discussion sections of articles are mainly in-discipline citations, such as citations from Nursing and Medicine in PLoS. 相似文献

本文以美国《科学引文索引》等四种大型检索工具为基础,统计出1988年我国被收录的科技论文总量为11853篇,世界排位第14,比1987年上升三位。论文增长率为 31.5％,居世界首位。我国论文数占世界论文总数的1.25％,比1987年略有上升。学科分布,基础学科5837篇,占47.1％;农业林业145篇,仅占1.2％。基础学科中物理学是领先学科,占52.5％。地区分布以京沪最多,机构分布以大学最多,占57.2％。文章指出,论文数量增长较快的根本原因是改革开放政策的正确执行。值得注意的是环境学科、生物学的论文减少,农业林业论文比重太小。向国外投稿的数量增多。指出了与国外的差距,并提出了具体建议。 相似文献

Digital formats are often popularly imagined to spell the ‘end’ of paper. In this essay I pose a series of questions about the importance of materiality for how researchers understand and work with archived paper documents. Drawing examples from research among literary papers and personal correspondence, I highlight the ways in which paper traditionally ‘disappears’ from the researcher’s view and ask whether the conditions of the digital turn may in fact provide for a return to ‘thinking through paper’. 相似文献
