The aim of this course is to give the participants a thorough introduction to science mapping, with a special emphasis on the VOSviewer software developed at CWTS. Participants are introduced into the main techniques for visualizing science. Special attention is paid to applications in a research evaluation and research management context. There are extensive possibilities for participants to practice with the VOSviewer software and to explore the functionality of the software in full detail. The course has an interactive format in which there is a lot of room for discussion and exchanging ideas.


The lecturers of the course are Ludo Waltman and Nees Jan van Eck, who are the developers of the well-known VOSviewer and CitNetExplorer software tools. The lecturers are prominent researchers in the field of scientometrics. Their work on science mapping is widely recognized. The lecturers also have an extensive experience with the application of science mapping in a research evaluation and research management context.


The course is targeted at participants with a professional interest in bibliometrics and visualization of science. The course is most beneficial for participants that already have some basic knowledge on bibliometrics, for example knowledge obtained by participating in the course Bibliometric Data Sources and Indicators. There is room for at most 30 participants.

In this blog post, two participants in the 2021 edition of the course share their experiences.


The next edition of the course, in January 2024, will be organized online.


The next edition of the course takes place in January 2025. The course consists of four half-day sessions. These sessions are scheduled in the afternoon European time.

While the course takes place online, participants based in the Netherlands are invited to join the first session  in person at CWTS, Leiden University. This offers an opportunity for Dutch participants to get to know each other and to meet the lecturers.
