Streszczenie (autorskie):

The talk gives a brief introduction to Rhetorical Structure Theory (RST, Mann/Thompson 1988) and then explains the design decisions for the Potsdam Commentary Corpus (PCC), which brings together RST, coreference, and other annotation layers on 175 German news editorials. After illustrating cross-layer queries on the corpus in the ANNIS linguistic database, we turn to the intricacies of manual RST annotation. I will give an overview of the annotation guidelines and their motivations, and present results from an (ongoing) study on annotator disagreements, from which we derive ideas for redesigning the annotation scheme (and potentially the underlying theory), with a comparison to the recent proposal of "eRST" by Zeldes et al. (2025). In the last part of the talk, I outline our results on automatic parsing using the system by Ji and Eisenstein (2014).
