Movies in Digital Humanities are often enriched with information by annotating the text e.g. via subtitles. However, we hypothesize that the missing presentation of the multimedia content is disadvantageous for certain annotation types like sentiment annotation. We claim that performing the annotation live during the viewing of the movie is benefic...
