This paper describes a rule-based approach to detect direct speech without the help of any quotation markers. As datasets fictional and non-fictional texts were used. Our evaluation shows that the results appear stable throughout different datasets in the fictional domain and are comparable to the results achieved in related work.
In diesem Beitrag wird das Redewiedergabe-Korpus (RW-Korpus) vorgestellt, ein historisches Korpus fiktionaler und nicht-fiktionaler Texte, das eine detaillierte manuelle Annotation mit Redewiedergabeformen enthält. Das Korpus entsteht im Rahmen eines laufenden DFG-Projekts und ist noch nicht endgültig abgeschlossen, jedoch ist für Frühjahr 2019 ein Beta-Release geplant, welches der Forschungsgemeinschaft zur Verfügung gestellt wird. Das endgültige Release soll im Frühjahr 2020 erfolgen. Das RW-Korpus stellt eine neuartige Ressource für die Redewiedergabe-Forschung dar, die in dieser Detailliertheit für das Deutsche bisher nicht verfügbar ist, und kann sowohl für quantitative linguistische und literaturwissenschaftliche Untersuchungen als auch als Trainingsmaterial für maschinelles Lernen dienen.
In this paper, we present our work-inprogress to automatically identify free indirect representation (FI), a type of thought representation used in literary texts. With a deep learning approach using contextual string embeddings, we achieve f1 scores between 0.45 and 0.5 (sentence-based evaluation for the FI category) on two very different German corpora, a clear improvement on earlier attempts for this task. We show how consistently marked direct speech can help in this task. In our evaluation, we also consider human inter-annotator scores and thus address measures of certainty for this difficult phenomenon.
This contribution presents a quantitative approach to speech, thought and writing representation (ST&WR) and steps towards its automatic detection. Automatic detection is necessary for studying ST&WR in a large number of texts and thus identifying developments in form and usage over time and in different types of texts. The contribution summarizes results of a pilot study: First, it describes the manual annotation of a corpus of short narrative texts in relation to linguistic descriptions of ST&WR. Then, two different techniques of automatic detection – a rule-based and a machine learning approach – are described and compared. Evaluation of the results shows success with automatic detection, especially for direct and indirect ST&WR.
