Mention relations can be visualized as a network graph. On this page, you can use VOSviewer to visualize the frequency with which different philosophers are mentioned in the same article (their 'co-mentions').
edhiphy and VOSviewer were used to create the graphics below; they are part of a chapter forthcoming in the Vienna Circle Yearbook, edited by Friedrich Stadler and Georg Schiemer.

Interpreting the results of a network plot is no simple task. The VOS viewer handbook is a good starting point to learn more. We are also planning to offer download formats that can be read by other programs, such as Gephi. If you would like to see a download option for a particular format, let us know.
