We created a restricted setup with a clear separation of authors, series and publishers between training and test data (i.e. authors which were in the training data, were not included in the test data etc.), and tested the subgenres in an one-vs-rest scheme. Figure 6 shows the results of this setup with at least 30 different combinations of test and training data per genre and a sample size of 200 novels split in half for training and test data.
