Data Analysis
Considering the respective properties and advantages, we simultaneously
used VOSviewer, the Bibliometrix R package, and CiteSpace.
VosViewer (version 1.6.18) is a bibliometric analysis software that can
be used for network construction and visualization based on
publications, countries and institutions, journals and co-cited
journals, authors and co-cited authors or
keywords[12-13]. In the visual network diagram
built by this software, a circle represents an analytical item, such as
a country, institution, journal, or author. The size of the circle
depicts the number of this item. Circles’ colors represent different
clusters. The thickness of the lines between the circles reflects the
degree of cooperation or co-citation between the analyzed items.
Bibliometrix R package (version 4.2.1) (https://www.bibliometrix.org)
was used to conduct the bibliometric and visualized analysis. Besides,
we used Bibliometrix to build the Bradford’s Law diagram, publications
geographic distribution maps, trend topic analysis, and the Sankey
diagram[14–15].
Bibliometric software CiteSpace (version 6.1.R3) was used to draw the
dual map of the journal[16-17]. In addition,
Microsoft Office Excel 2019 was used to graph the quantitative analysis
of the publication.
