本文以中国科学技术信息研究所建立的《中国科技期刊论文与引文数据库》(CSTPCD)为基础,利用荷兰阿姆斯特丹大学Loet Leydesdorff教授开发的系列程序,将发生引用或被引关系的期刊聚集起来,然后利用可视化工具(Pajek)将期刊之间的引用/被引信息进行可视化表达.通过分析计算机学科领域的重要期刊《软件学报》和《计算机学报》的核心引用和被引环境,发现该领域的论文作者更愿意引用国际期刊,而对国内期刊论文的引用比例很小;尽管《软件学报》的影响因子略小于《计算机学报》,但前者在国内计算机科学类期刊中影响最大.有趣的是,当阈值为1%时,两种期刊在2003年的引用或被引环境中所包含的期刊数目完全一样;同样情形发生在2004年两刊的被引环境中. 相似文献

调查2001-2010年度《中国医学科学院学报》在中国知网的零被引率,结果显示《中国医学科学院学报》2001-2010年度总零被引率为15.6％,总刊载论文零被引率为12.2％,总刊载基础医学论文零被引率为13.9％,总刊载临床医学论文零被引率为11.3％.对刊载论文引文的分析结果显示,《中国医学科学院学报》2001-2010年度共刊载基础医学论著665篇、临床医学论著607篇、基础医学综述100篇、临床医学综述138篇,篇均引用参考文献分别为12.2、10.7、31.5、19.5条,外文参考文献比例分别为86.4％、80.5％、94.9％、85.5％.研究结果提示,我国高素质基础和临床医学研究人员在写作时强烈倾向引用外文文献,作者的引用习惯可影响中文期刊的零被引率. 相似文献

期刊引用认同指标在期刊评价中的适用性分析 总被引：1，自引：1，他引：0
论文以CSSCI图书情报领域的18种期刊为例,以这些期刊在2009年全年登载论文的参考文献为研究对象,从CSSCI数据库中获取数据,统计分析各期刊的引用认同。结果显示:期刊引用认同指标(引文量、篇均引文量、英文引文比、期刊引用广度、自施引率、引用半衰期、期刊集中因子、认同期刊影响力等指标)与CSSCI来源期刊定量与定性评价指标并不明显相关,但这类指标可以反映期刊载文的内容特征与偏好、对国外科学文献和对其他学科文献的利用程度、期刊的办刊定位、学科的发展模式等等,在综合评价期刊方面具有一定意义。 相似文献

中国作者对发表SCI论文有巨大的需求,但目前SCIE收录的中国期刊数量较少,且总体水平未达到世界平均水平。将SCI-E收录的中国期刊根据语种和论文作者的国籍进行分类后发现:甲类期刊(以中文刊载的论文大于50%)和乙类期刊(发表论文的作者至少50%来自中国,且至少50%的论文以英文形式发表)学术水平未达到国际平均水平,2001—2011年期间变化不大;但乙类期刊是SCI-E收录的中国期刊中的绝大多数。丙类期刊(其刊载的论文至少50%是以英文发表的,且至少50%的论文第一作者为非中国作者)引用指数(JCS)逐年上升,上升幅度明显,2011年超过国际平均水平。说明通过改变语种不能提高期刊的国际影响力。在这3类期刊中,丙类年刊均载文量最低,为117.27篇/刊,2007后呈逐年下降趋势,2011年甚至降至91.07篇/刊。中国被SCI-E收录的期刊数量少,与国内发表SCI论文的巨大需求,以及中国期刊走上国际舞台,发挥更大的学术影响力的需求差距甚远,的确有必要创办更多的英文科技期刊;但是在此过程中,有必要慎重评价SCI-E收录期刊的学术影响力和作用。 相似文献

以SJR为数据来源,比较分析了1996-2008年巴西、印度、中国、韩国4个国家发表科技论文数量、可引用文献量、文献被引量、自引量、篇均被引量、去除自引后的篇均被引量、H指数、文献引用率、国际合作量等9个指标。中国发表论文数最多,2003年后每年增加约3万篇。巴西、韩国文献引用率、篇均引用量高,且自引率低;印度居中等水平;中国文献引用率、篇均引用率低且自引率高;国际合作度巴西最高、中国最低。可见中国的科技论文质量与其他3个国家相比,还有一定的差距。 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

A global survey conducted by arXiv in 2016 showed that 58% of arXiv users thought arXiv should have a peer review system. The current opinion is that arXiv should adopt the Community Peer Review model. This paper evaluates and identifies two weak points of Community Peer Review and proposes a new peer review model – Self‐Organizing Peer Review. We propose a model in which automated methods of matching reviewers to articles and ranking both users and articles can be implemented. In addition, we suggest a strategic plan to increase recognition of articles in preprint databases within academic circles so that second generation preprint databases can achieve faster and cheaper publication. 相似文献

Many journals post accepted articles online before they are formally published in an issue. Early citation impact evidence for these articles could be helpful for timely research evaluation and to identify potentially important articles that quickly attract many citations. This article investigates whether Microsoft Academic can help with this task. For over 65,000 Scopus in-press articles from 2016 and 2017 across 26 fields, Microsoft Academic found 2–5 times as many citations as Scopus, depending on year and field. From manual checks of 1122 Microsoft Academic citations not found in Scopus, Microsoft Academic’s citation indexing was faster but not much wider than Scopus for journals. It achieved this by associating citations to preprints with their subsequent in-press versions and by extracting citations from in-press articles. In some fields its coverage of scholarly digital libraries, such as arXiv.org, was also an advantage. Thus, Microsoft Academic seems to be a more comprehensive automatic source of citation counts for in-press articles than Scopus. 相似文献

This article analyzes the bibliometric features (the number of pages, completion years, the fields of subject, the number of citations, and their distribution by types of sources and years) of 100 theses and dissertations completed at the Department of Librarianship of Hacettepe University between 1974 and 2002. Almost a quarter (24%) of all dissertations were on university libraries, followed by public libraries (9%). Doctoral dissertations were, on average, twice as long as master's theses and contained 2.5 times more citations. Monographs received more citations (50%) than journal articles did (42%). Recently completed theses and dissertations contained more citations to electronic publications. Fourteen (or 3.2% of all) journal titles (including Türk Kütüphaneciliği, College & Research Libraries, and Journal of the American Society for Information Science) received almost half (48.9%) of all citations. Eighty percent of journal titles were cited infrequently. No correlation was found between the frequency of citations of the most frequently cited journals and their impact factors. Cited journal titles in master's and doctoral theses and dissertations overlapped significantly. Similarly, journal titles cited in dissertations also overlapped significantly with those that were cited in the journal articles published in the professional literature. The distribution of citations to foreign journal titles fit Bradford's Law of Scattering. The mean half-life of all cited sources was 9 years. Sources cited in master's dissertations were relatively more current. Single authorship was the norm in cited resources. Coupled with in-library use data, findings of the present study can be used to identify the core journal titles in librarianship as well as to evaluate the existing library collections to decide which journal titles to keep, discard, or relegate to off-site storage areas. 相似文献

This study examines how the social sciences' debate between qualitative and quantitative methods is reflected in the citation patterns of sociology journal articles. Citation analysis revealed that quantitative articles were more likely to cite journal articles than monographs, while qualitative articles were more likely to cite monographs than journals. Quantitative articles cited other articles from their own quantitative-dominated journals but virtually excluded citations to articles from qualitative journals, while qualitative articles cited articles from the quantitative-dominated journals as well as their own qualitative-specialized journals. Discussion and conclusions include this study's implications for library collection development. 相似文献

本文以17个论文高产出国家（地区）论文数及被引用次数的数据与ROAR、Open DOAR和RWR三个知识库网站用户注册的知识库数量为依据,得出论文数、论文被引次数与知识库数量之间存在显著相关。并在此基础上,对在RWR网站中17个国家（地区）的知识库排名区间分布进行了统计。研究表明,我国知识库建设,不仅在数量上有较大差距,而且在质量上也处于劣势,提出既要重视知识库理论研究,也要重视知识库实际建设,同时应充分认识知识库开放存取对论文被引的积极作用。 相似文献

This article presents a citation analysis of articles published in 2011 from 11 kinesiology journals. The results of the citation analysis of 11 kinesiology journals are compared to a citation analysis of articles published in 2011 by faculty in the School of Kinesiology, University of Michigan. Comparing the four areas of kinesiology, Movement Science, Athletic Training, Sports Management, and Physical Education, the results show that articles published in Movement Science and Athletic Training cited a higher percentage of journal articles than articles published in Sports Management and Physical Education. While some of the materials cited went as far back as 1874, the mean age ranged from 1996 to 2004. Human Kinetics was the most cited publisher and the American Journal of Sports Medicine was the most cited journal. The University of Michigan Library owns 75% of the materials cited in the publications cited by School of Kinesiology faculty. Faculty in the School of Kinesiology cited many textbooks, a format not actively collected by the library before this analysis. 相似文献
