摘要
ESI高被引论文及热点论文往往代表一个领域的权威科研成果,而对这些论文的特征进行可视化地分析能够帮助该领域研究人员及时掌握主流的研究趋势并选定合适的研究方向。文章将ESI数学研究领域的高被引论文及热点论文作为数据来源,用WoS数据库进行必要扩展,再选取InCites和VOSviewer作为研究工具,从多个角度进行可视化分析。从最终生成的图表中可以看出:发展中国家及地区在数学研究领域表现较为突出,我国也在发文数量、被引频次等指标上处于领先地位;目前数学领域最为热门的研究方向是应用数学,相关方向论文占比达到50%;数学建模成为各个国家关注的焦点;世界范围内数学领域研究的合作非常紧密。
ESI highly cited papers and hot papers often represent authoritative scientific research achievements in a field,and visual analysis of the characteristics of these papers can help researchers in this field timely grasp the mainstream research trends and select appropriate research directions.This paper takes the highly cited papers and hot papers in the field of ESI mathematics research as the data source,expands the WoS database,and then selects InCites and VOSviewer as the research tools for visual analysis from multiple angles.It can be seen from the final chart:developing countries and regions are more prominent in the field of mathematics research,and China is also in the leading position in the number of documents issued and the frequency of citations;at present,the most popular research direction in the field of mathematics is applied mathematics,and the proportion of papers in related directions reaches50%;mathematical modeling has become the focus of attention in various countries;the research cooperation in the field of mathematics is very close all over the world.
