Russian scientific publications 2005–2009 in the science citation index,scopus, and chemical abstracts databases

This paper presents the results of a bibliometric study of the scientific publications that are affiliated with Russia and included in multidisciplinary databases, such as Science Citation Index and Scopus, as well as in the specialized Chemical Abstracts database, in the period from 2005 to 2009. Major bibliometric indicators, including citation indexes, are explored. It is shown that the Scopus database contains most of the Russian publications in the period from 2005 to 2009. While a gradual decrease in the number of peer-reviewed Russian-language journals constitutes a general trend for all three databases, the Chemical Abstracts database leads in terms of the coverage of these journals. It is found that despite the large number of translated versions of journals, Russian publications are still significantly late in their coverage by foreign databases, which has a significant impact on their citation levels.     

Kazakh analogue of the science citation index (SCI) as an important parameter of scientific research activities

The purpose of the Kazakh publication citation indicator that has been developed in Kazakhstan since 2005 is to carry out scientometric analysis of scientific publications to determine their citation rate. At present, the bibliographic database (BDB) on citation includes information on the publication activities and citation index of approximately 30000 Kazakh scientists and specialists. They had over 18000 scientific papers published in over 500 domestic and foreign journals. The total quantity of references to papers by Kazakh scientists was more than 28000. The Kazakh analogue of the science citation index determination system is an efficient tool for analytical work with the BDB of scientific publications, which makes it possible to calculate publication activities and citation parameters, which are used to define the value and demand for the results of scientific work in various fields of domestic science.

科研合作对期刊论文被引频次的影响

以图情类影响力最大的4种期刊在2000-2009年的载文量与被引频次为样本,采用符号检验与相关分析的方法,从合作模式与合作频率两个方面分析科研合作对期刊论文被引频次的影响。研究发现：①合作发表论文的影响力明显高于独立（无合作）发表的论文;②在获得被引频次方面,国际合作并不优于国内合作,高校并不优于研究所;③研究机构的合作次数与被引频次呈正线性相关关系,但机构的合作频率与篇均被引次数没有显著相关。     

A systematic empirical comparison of different approaches for normalizing citation impact indicators

We address the question how citation-based bibliometric indicators can best be normalized to ensure fair comparisons between publications from different scientific fields and different years. In a systematic large-scale empirical analysis, we compare a traditional normalization approach based on a field classification system with three source normalization approaches. We pay special attention to the selection of the publications included in the analysis. Publications in national scientific journals, popular scientific magazines, and trade magazines are not included. Unlike earlier studies, we use algorithmically constructed classification systems to evaluate the different normalization approaches. Our analysis shows that a source normalization approach based on the recently introduced idea of fractional citation counting does not perform well. Two other source normalization approaches generally outperform the classification-system-based normalization approach that we study. Our analysis therefore offers considerable support for the use of source-normalized bibliometric indicators.     

A new approach to the metric of journals’ scientific prestige: The SJR indicator

A size-independent indicator of journals’ scientific prestige, the SCImago Journal Rank (SJR) indicator, is proposed that ranks scholarly journals based on citation weighting schemes and eigenvector centrality. It is designed for use with complex and heterogeneous citation networks such as Scopus. Its computation method is described, and the results of its implementation on the Scopus 2007 dataset is compared with those of an ad hoc Journal Impact Factor, JIF(3y), both generally and within specific scientific areas. Both the SJR indicator and the JIF distributions were found to fit well to a logarithmic law. While the two metrics were strongly correlated, there were also major changes in rank. In addition, two general characteristics were observed. On the one hand, journals’ scientific influence or prestige as computed by the SJR indicator tended to be concentrated in fewer journals than the quantity of citation measured by JIF(3y). And on the other, the distance between the top-ranked journals and the rest tended to be greater in the SJR ranking than in that of the JIF(3y), while the separation between the middle and lower ranked journals tended to be smaller.     

科学文献网络中的引文扩散——以2011年诺贝尔化学奖获奖论文为例

科学知识借助引用关系发生动态扩散,客观记录科学发展与演化的轨迹。由于知识之间存在千丝万缕的联系,以孤立的观点看待科学知识的影响与价值往往得到的是片面的感观。本文从联系的视角观察科学知识产出,尝试通过被引、引用、文献耦合与共被引等文献关系为单篇论著构建引文扩散网络,探讨"文献嵌入网络"的概念、测度方式及其在引文扩散过程中起到的特殊作用。案例分析显示,科学知识的形成相伴于科学知识网络的发展,同时也受到这个网络的影响:科学知识向科学领域的扩散,遵循从核心领域向周边领域的扩散模式;施引文献可以揭示目标文献中没有显式呈现的信息;四种文献关系之间可能存在相当程度的重合,引文扩散过程显示出知识的"黏滞性"与非常明显的"小世界"特征。对科学产出的扩散网络进行量化有助于为全面评价其价值提供更多客观依据。     

Selection of Periodicals to Support Nanotechnology Research

A comprehensive method for the selection of international scientific periodicals necessary for high-quality research in specific life sciences and technology problems is presented. This method is based on the analysis of citations considering both the citedeness of selected editions in specialized journals and their citing to specialized journals. A list of international journals and other periodicals that are vital for high-quality nanotechnology research was obtained. Based on this list, the development of a documentary constituent of the scientific information environment using a research library to support nanotechnology research is expected. A final list consisting of 572 items was compiled based on the application of “threshold” values and the aggregation and exclusion of data.     

关于利用被引频次支付期刊论文部分稿酬的尝试

目前,国内期刊社关于论文作者稿酬的支付没有统一的标准,有的期刊社不支付稿酬,有的期刊社稿酬支付仍然沿用1999年发布的《出版文字作品报酬规定》,还有些期刊社采取优稿优酬制度,导致作者意见较多。为了更加公平合理地给期刊论文作者支付稿酬,建议国内期刊社可采用基本稿酬+被引频次支付部分稿酬的办法,并就其依据、实施方法、统计被引频次时间范围、不同期刊引用区别对待及其应用的可行性进行分析总结。     

基于K-means聚类的期刊操控引用行为特征指标研究

认为部分期刊为了追求被引排名,开始操纵期刊的引用。这样的行为影响了期刊引文数据的质量以及利用引文开展的科学研究的可靠性。提出引文年代集中度、自引率、被引密度和引用密度4个引文指标用于识别期刊是否存在操纵引用的行为,并采用数据挖掘中的K-means聚类方法检验指标的有效性,实验结果显示这些指标都达到了较好的识别效果。

Interactive journal concept for improved scientific publishing and quality assurance

Many scientific publications are careless, useless or false, and inhibit scholarly communication and scientific progress. This is caused by the failure of traditional journal publishing and peer review to provide efficient scientific exchange and quality assurance in today's highly diverse world of science. The most promising way to improve matters is a two‐stage (or multi‐stage) publication processes with interactive peer review and public discussion in new and traditional scientific journals. A concept for such interactive scientific journals is outlined, and its applicability is demonstrated by the open access journal Atmospheric Chemistry and Physics.

The Publication Success of 102 Nations in Scopus and the Performance of Their Scopus-Indexed Journals

Over the years, the number of journals indexed in Scopus has increased, although it varies significantly between countries. The increasing proportion of international journals of a country provides new venues for papers from that country to be seen by other researchers worldwide. In this work, we evaluate the relationship of a country’s scientific performance or publication success with both its journals’ quantity and quality. The specific objective of the study is to identify the relationship between the country’s publication success and the quantity and quality of those country’s journals indexed in Scopus during 2005–2014. The publication success of 102 individual countries, measured by their scientific productivity, impact and collaboration indicators, the quantity of country’s Scopus-indexed journals in 2014 (a total of 22,581 journals) as well as the quantity of its journals were investigated. Scopus-indexed journals are predominantly from Western Europe (48.9%) and North America (27.7%), with the United States and the United Kingdom dominate with a total 51%. The contribution from the peripheral countries is comparatively small, however there are a good number of contributions from the South-East Asian countries. Estonia is the fastest growing country in terms of having indexed journals in Scopus, following by Iran and Malaysia. Among the studied indices, it was found that publication success (total publications and total citations) of 102 countries are strongly correlated with quantity (number of indexed journals and number of documents published in indexed journals) and quality (citations per paper, SJR, h-index, CiteScore and SNIP) indicators of country’s journals. We can conclude that the scientific productivity of a country depend critically on the number of journals indexed from that country in citation databases. The study provides a context with which the relative success of publications can be assessed, yielding new insights into the scientific impact of individual countries and the performance of journals that they published.     

SCI的引文统计指标及其与研究评价的关系

从引证类型和检索系统统计源期刊组成分析SCI的引文统计数据及相关指标与期刊和论文学术水平间的不对应关系，并从引文统计时段、论文类型和期刊大小等方面探讨影响因子本身的不确定性；通过分析中国科技期刊的被引情况指出SCI中引文数据的统计错误。认为在我国的科研成果和学术期刊评价中，一定要具体分析SCI的统计数据，适度、合理地使用引证分析方法。     

The citation speed index: A useful bibliometric indicator to add to the h index

The scientific impact of a publication can be determined not only based on the number of times it is cited but also based on the citation speed with which its content is noted by the scientific community. Here we present the citation speed index as a meaningful complement to the h index: whereas for the calculation of the h index the impact of publications is based on number of citations, for the calculation of the speed index it is the number of months that have elapsed since the first citation, the citation speed with which the results of publications find reception in the scientific community. The speed index is defined as follows: a group of papers has the index s if for s of its N_p papers the first citation was at least s months ago, and for the other (N_p ? s) papers the first citation was ≤s months ago.     

我国国际论文的真实影响力分析

科学研究的目的在于创造知识,并应用理论成果解决我国社会、经济、文化等发展中的实际问题。将论文发表在国际期刊上可以让更多的国际同行了解我国最新的科研成果,为我国获得更多的国际影响力,所以在过去二十多年里SCI论文成为我国科研考核的一个重要指标。在这种科研评价导向下,我国学者发表的国际论文数量已居世界第一位,而大量来自国内同行的引用使得我国国际论文的被引量排名世界第二。本文提取1990至2015年Web of Science论文及其引文的数据,分析不同国家、不同学科在国家层次的自引情况,并在不同国家、不同学科之间进行比较。研究发现,在排除国内同行的自引后,我国国际论文的真实国际影响力仍然有限,除了临床医学和物理等少数学科外,其他学科仍然低于全球平均水平。
