Characterizing references from different disciplines: A perspective of citation content analysis

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.

引文半衰期与普赖斯指数之间的数量关系研究

本文运用文献计量学方法,对SCIE收录的106种力学专业期刊文献所附的2869099条参考文献进行了分析,考察了力学专业领域引文半衰期和普赖斯指数之间的关系,并用同时法计算了引文半衰期和普赖斯指数,将引文半衰期和普赖斯指数进行了比较。研究结果表明,引文半衰期和普赖斯指数成反比变化,引文半衰期和普赖斯指数之间存在着简单的数量关系:P(4)*H=2(P为普赖斯指数,H为引文半衰期)。通过普赖斯指数P(4)可以简便地近似计算引文半衰期,并具有较高的精度。     

参考文献首页复印件对科技论文参考文献编校质量影响的定量研究

Non-linearity between referencing behavior and citation impact: A large-scale,discipline-level analysis

References formulate the foundation and endorsements of scientific research. Using articles published in 2005 covered by Microsoft Academic Graph, the current paper defines and calculates five indicators of references, i.e., the number of references, the number of citations of references, the age of references, the number of nodes in a reference cascade (a multi-generation reference network), and the density of bibliographic coupling networks by references, and investigates their relations with the citation impact of the focal publication. A non-linear relationship is shown in all the five indicators; specifically, we observe two types of patterns, namely inverted-L and -U relations, both presenting the existence of critical points. We further explore the discipline-level differences of such a relationship and how it relates to the characteristics of the discipline itself. Among all five indicators, the effect of disciplinary academic “environments” is universally identified. We believe that the current paper provides insightful views to the discussion regarding the significance of a reference list.

Bibliography of Bioethics and Index Medicus: comparison of coverage, publication delay, and ease of recall for journal articles on bioethics

Citations selected from the bibliographies of recent texts, a specialized subject bibliography, and review articles were checked in both Cumulated Index Medicus (IM) and the Bibliography of Bioethics (BB) to compare coverage, publication delay, probable causes of indexing and retrieval failure, and the ease with which relevant citations were retrieved. The study also attempted to determine whether BB included appropriate articles from the MEDLINE database in a timely and systematic manner. While 98% of the IM citations appeared within a year of publication, 79% of the BB citations appeared two to three years after their publication dates. The average citation appeared twice as frequently in IM as in BB.

The negative effects of citing with a national orientation in terms of recognition: National and international citations in natural-sciences papers from Germany,the Netherlands,and the UK

Nations can be distinguished in terms of whether domestic or international research is cited. We analyzed the research output in the natural sciences of three leading European research economies (Germany, the Netherlands, and the UK) and ask where their researchers look for the knowledge that underpins their most highly-cited papers. Is one internationally oriented or is citation limited to national resources? Do the citation patterns reflect a growing differentiation between the domestic and international research enterprise? To evaluate change over time, we include natural-sciences papers published in the countries from three publication years: 2004, 2009, and 2014. The results show that articles co-authored by researchers from Germany or the Netherlands are less likely to be among the globally most highly-cited articles if they also cite “domestic” research (i.e. research authored by authors from the same country). To put this another way, less well-cited research is more likely to stand on domestic shoulders and research that becomes more highly-cited is more likely to stand on international shoulders. A possible reason for the results is that researchers “over-cite” the papers from their own country – lacking the focus on quality in citing. However, these differences between domestic and international shoulders are not visible for the UK.

基于文献老化负指数方程的半衰期与普赖斯指数关系的研究

从Brookes文献老化的负指数方程出发,推导出引文半衰期和普赖斯指数之间的关系式,证明他们之间不是反比关系,并用此关系式重新拟合了陈立新等人的数据。拟合结果表明：该关系式可以很好地拟合1954-1968年的数据,拟合1969-2003年的数据则出现较大的偏差。其原因可能是随着科学技术的进步,SCIE力学专业期刊的引文半衰期对普赖斯指数的变化率比理论值要快。此外,拟合结果还揭示SCIE力学期刊中的经典文献的引文半衰期在较长时间内是不变的。     

Bibliometric Research of International Scientific Conferences Proceedings in the Context of the Current Objectives of Library and Information Service

ABSTRACT

The possibilities of the applications of the structure of bibliographical references in the proceedings of international scientific conferences for the management of information and library service are under discussion. On behalf of such research branches that do not have any specialized periodicals and which researchers are involved in other branches, too, it is demonstrated that the international scientific conference proceedings could be the only reliable source of references that adequately represent such branches and could be used for corresponding bibliometric studies. The results of the studies of disciplinary, chronological and species structures of references cited in the proceedings of the conferences in magnetic fluids and in bone marrow purging and processing are featured and discussed. Some results of detailed citation study of the citedness of particular authors are also presented. It is shown that the practice of taking into account the citation figures referring to only the first co-authors destroys the real picture of impact of individuals (in contrast to what Ferreiro, Ortega & Lara tried to demonstrate in 1977). The basic conclusion: there is a need in the bibliographical index of the proceedings of international scientific conferences of the citation index type.     

由Web of Science数据库分析高影响力中华医学会系列期刊引发的思考

通过Web of Science数据库的“被引参考文献检索”途径,将中华医学会123种非SCI期刊作为国内大量的非SCI科技期刊的代表,统计其刊载文献被SCI期刊引用的情况;以被引文献数量大于50篇作为高影响力期刊的筛选条件,分析其中高影响力期刊的被引文献数量、单篇被引文献最高引用频次、施引文献数量、施引文献最高被引频次以及施引文献的国家地区分布、出版年份分布,从而了解这些非SCI科技期刊的国际影响力.基于这一分析,认为SCI期刊并非是获得同行认可的唯一途径,国内大量的非SCI科技期刊应走“立足国内,面向世界”的发展道路,以踏实做专业领域内有影响力的期刊为目标;同时呼吁国家有关部门能对现行科研评价指标进行调整,鼓励质量上乘的稿件能选择具有影响力的国内期刊发表.
