论文摘要
某个领域的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特定于领域的知识的增加。在本文中，我们提出了一种方法论方法，可以分析较低聚集水平的科学动力学，即研究领域的水平。我们的趋势分析方法能够发现非常最新的趋势，并且用于研究趋势的方法对于可能的结果可能很容易理解。为了证明趋势分析方法，我们专注于2014年至2020年之间化学（及相关领域）的年度出版物数量（和专利），以识别具有最高动态的化学领域（出版物计数的最大变化率）。该研究基于单学科文献数据库caplus。我们的结果表明，自多年来，CapLus数据库中的出版物数量正在增加。近年来，人们发现有关光学现象和电化学技术的研究是新兴的主题之一。
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.
