Conference Paper
Full-text available
We present first results of an exploratory study about sentiment analysis via different media channels on a German historical play. We propose the exploration of other media channels than text for sentiment analysis on plays since the auditory and visual channel might offer important cues for sentiment analysis. We perform a case study and investig...

We present results of a project on emotion classification on historical German plays of Enlightenment , Storm and Stress, and German Classicism. We have developed a hierarchical annotation scheme consisting of 13 sub-emotions like suffering, love and joy that sum up to 6 main and 2 polarity classes (positive/negative). We have conducted textual ann...

Movies in Digital Humanities are often enriched with information by annotating the text e.g. via subtitles.

Project
The aim of "Emotions in Drama" is to explore and analyze emotion concepts in historical German plays of around 1650-1815 via computational methods of emotion classification. We develop annotation concepts for emotions that are directed towards the interests of literary scholars. To gather training material for algorithms, a sub-set of our corpus will be annotated according to the annotation schemes. On the computational side, we explore primarly transformer-based models (BERT, ELECTRA) trained on contemporary and historical texts. Our final goal is to develop algorithms with satisfactory levels of performance to explore large-scale questions like how emotions are distributed across different genres or how the usage of emotions changed throughout time.
