Beschreibung
Previous research in the research group has focused on two main areas: First, building on the
work of Andre et al. (2023), Eliaz & Spiegler (2020) and others, a survey has been conducted
and narratives have been represented in the form of "directed acyclic graphs" (DAGs, Pearl,
2009). Second, based on the DAGs of Andre et al. (2023), a study of the distribution of
narratives in a large text corpus (Dow Jones Newswires) was conducted using a semisupervised topic model (keyATM). The results of the study by Andre et al (2023) were used for
the structural identification of the text model.
