Bibliometric Coupling Analysis of COVID-19 Literature
For more information about what a bibliometric coupling analysis is, please see the about page.
Applications for the bibliometric coupling results:
- Organizes published articles by topics, enables the reader to identify articles within an area of interest.
- It is a complementary way to identify related research. The results are not based on search terms, so identifying related articles through this method opens the possibility to make valuable and novel connections between research articles.
To access the interactive map, you need to open the graph in VosViewer, which allows you to search the map, see article information on each node in the graph diagram, and by clicking on the node, open the article in a browser window.

Network Visualization of Bibliometric Coupling Analysis of COVID-19 Literature as it looks like at July 20th, 2020
This week’s post is a little different. This week we look at articles published in the past four weeks, making our corpus: 10735 documents, downloaded from Scopus. 2023 of these included reference lists and were included in the analysis. For the analysis, we used linlog and total link strength.
The minimum cluster size was set to 15. There are 6 main clusters in the map. Similar to the co-occurrence analysis, the cluster structure seems very similar to that of all research, indicating general stability in the topics and types of research published.
