Presentation at the International Conference on ICT enhanced Social Sciences and Humanities 2020, July 1, 2020. It is essential for researchers to have an up-to-date understanding of the literature in their research field. However, keeping up with all relevant literature is highly time consuming. Bibliometric visualizations can support this task. These visualizations provide intuitive overviews of the literature in a research field, enabling researchers to obtain a better understanding of the structure and development of a field and to get an impression of the most significant contributions made in the field. In this talk, I will give an introduction to two software tools for bibliometric visualization: VOSviewer (www.vosviewer.com) and CitNetExplorer (www.citnetexplorer.nl). VOSviewer is a popular tool for visualizing bibliometric networks of publications, authors, journals, and keywords. CitNetExplorer is a tool for the visualization and analysis of citation networks of scientific publications. I will pay special attention to applications of VOSviewer and CitNetExplorer in the social sciences and humanities, focusing in particular on the use of advanced text mining, network analysis, and visualization techniques for analyzing large amounts of textual data.
