Bibliometrics 文獻計量分析 is the use of statistical methods to analyze research literature to observe patterns of research publication data. The explosion of research publications has generated big bibliographical data, that has substantialized correlational analysis for observing patterns and trends of research publication such as CDL related research. Here below are a guidance of VOSviewer with few testing bibliometric samples related to CDL research presented by VOSviewer. (For information, CiteSpace is another bibliometric program recommended).
1. How to use VOSviewer Software
VOSviewer is a software which can provide such bibliographical analysis. created by Nees Jan van Eck and Ludo Waltman, researchers at the Centre for Science and Technology Studies (CWTS) of Leiden University in the Netherlands. For information, please view the creators’ presentations closely below:
