Large-scale analysis of bibliometric networks: Tools, techniques, and applications
Abstract
The analysis of bibliometric networks has the potential to offer deep insights into the structure and dynamics of science. I will provide an overview of research into bibliometric network analysis at the Centre for Science and Technology Studies (CWTS) of Leiden University. Two popular software tools for the analysis and visualization of bibliometric networks have been created at CWTS. These tools, VOSviewer (www.vosviewer.com) and CitNetExplorer (www.citnetexplorer.nl), will be demonstrated and the underlying network analysis techniques will be discussed. A number of large-scale applications of bibliometric network analysis will be presented. One application investigates the degree to which network science is evolving to become a single unified research field. Other applications are concerned with research planning and research evaluation. In these applications, bibliometric network analysis is used to identify the key research strengths of a university, to study the interdisciplinary nature of modern science, and to detect new emerging research areas.
Biography
Ludo Waltman is a senior researcher at the Centre for Science and Technology Studies (CWTS) of Leiden University, where he leads the research program on advanced bibliometric methods. Ludo’s research interests focus on methodological topics in the field of bibliometrics and scientometrics, in particular the analysis and visualization of bibliometric networks and the development of bibliometric indicators. Together with his colleague Nees Jan van Eck, Ludo has developed two software tools for the analysis and visualization of bibliometric networks: VOSviewer and CitNetExplorer. Ludo serves as Editor-in-Chief of Journal of Informetrics, one of the leading journals in the field of bibliometrics and scientometrics. Ludo also has an extensive experience in the use of bibliometric network analysis in commissioned research projects for universities, research funders, and scientific publishers.
Workshop ‘Network visualization using VOSviewer’
VOSviewer (www.vosviewer.com) is a popular software tool for network visualization developed at the Centre for Science and Technology Studies (CWTS) of Leiden University. The main focus of the tool is on visualizing bibliometric networks, in particular co-authorship networks, citation networks, and term co-occurrence networks, but VOSviewer can also be used for visualizing all kinds of non-bibliometric networks. This workshop offers an introduction into the VOSviewer tool. Ludo Waltman, one of the developers of VOSviewer, will guide the workshop participants through an interactive tutorial that provides the participants with extensive hands-on experience with VOSviewer. At the end of the workshop, participants will be able to create their own network visualizations using VOSviewer. This includes not only visualizations of bibliometric networks constructed based on data from databases such as Web of Science, Scopus, and PubMed, but also visualizations of other types of networks, including term co-occurrence networks constructed from a large text corpora using VOSviewer’s text mining features.
Workshop participants are kindly requested to bring a laptop with them.
