In order to gain an insight into the influence of genre and publisher on the text form, we use Ivis (Szubert 2019) for unsupervised dimensionality reduction. The coloring of the data points according to publisher (figure 3) and genre (figure 4) shows the strong influence of these variables on the texts. It is also clear that Cora Verlag allows less variance among genres and thus becomes the most discriminatory factor. Figure 5 shows a detail of the previous plot, but focuses on microstructures. Theses structures indicate, that on this level genre and publisher are not enough to explain the distribution and that something else – author or series – comes into play.
