研究领域近期时间动态的实证分析:以化学及相关领域的年度出版物为例

Empirical analysis of recent temporal dynamics of research fields: Annual publications in chemistry and related areas as an example

Lutz Bornmann, Robin Haunschild

摘要:

某一领域出版物数量的变化可能反映了该领域科学进步的动态,因为出版物数量的增加可以解释为该领域特定知识的增加。在本文中,我们提出了一种方法论的方法来分析科学的动态较低的聚合水平,即,研究领域的水平。我们的趋势分析方法能够揭示最近的趋势,并且用于研究趋势的方法对于结果的可能接收者来说易于理解。为了展示趋势分析方法,我们在这项研究中重点关注了2014年至2020年期间化学(及相关领域)的年度出版物(和专利)数量,确定了化学领域中动态最高的领域(出版物数量变化率最大)。该研究基于单学科文献数据库CAplus。我们的研究结果表明,CAplus数据库中的出版物数量多年来一直在增加。光学现象和电化学技术的研究是近年来新兴的课题之一。

英文摘要:

Changes in the number of publications in a certain field might reflect the dynamic of scientific progress in this field, since an increase in the number of publications can be interpreted as an increase in the field-specific knowledge. In this paper, we present a methodological approach to analyse the dynamics of science on lower aggregation levels, i.e., the level of research fields. Our trend analysis approach is able to uncover very recent trends, and the methods used to study the trends are simple to understand for the possible recipients of the results. In order to demonstrate the trend analysis approach, we focused in this study on the annual number of publications (and patents) in chemistry (and related areas) between 2014 and 2020 identifying those fields in chemistry with the highest dynamics (largest rates of change in publication counts). The study is based on the mono-disciplinary literature database CAplus. Our results reveal that the number of publications in the CAplus database is increasing since many years. Research regarding optical phenomena and electrochemical technologies was found to be among the emerging topics in recent years.
