This computerlinguistic project tests theories of questions under discussion (QUDs) and discourse structure. The project proceeds in two phases: In the first phase (corpus annotation), a natural language corpus of newspaper articles is compiled and annotated with QUD-tree structures following Riester et al. (2018), which have the same structure as SDRT-graphs, to represent their discourse structure and content. In the second phase (NLG), texts are generated from these QUD-tree structures, and the similarity of the generated texts to the originals is evaluated. Special attention is given to discourse relations and their explicit discourse markers, non-at-issue content, evaluative and expressive adverbs, topic and focus, and sentence aggregation.
