Presentation at the Workshop on Open Citations, University of Bologna, Bologna, Italy, September 4, 2018.
I will demonstrate the use of the VOSviewer software (www.vosviewer.com), of which I am one of the developers, for creating bibliometric visualizations of science based on openly available bibliographic data sources. Both the use of Crossref data and the use of data from the OpenCitations Corpus will be demonstrated. In addition, I will show how data from Dimensions can be used. The possibilities and limitations of the currently available open data sources will be discussed, also in comparison with more established data sources such as Web of Science and Scopus. Finally, I will provide my perspective on future developments, focusing especially on the integration of open data sources and visual analysis tools.
