Discourse parsing within the Rhetorical Structure Theory (RST) framework has inspired extensive research; however, it remains prone to significant levels of annotator disagreement, particularly in the labeling of relations and nuclearity. This paper investigates systematic discrepancies in RST annotations, focusing on two expert-annotated corpora of closely related languages. We first compare different RST treebanks to assess the availability of parallel-labeled data and highlight their usefulness for studying disagreement. We then perform both quantitative and qualitative analyses of annotation divergences, identifying factors that contribute significantly to inconsistent interpretations. Finally, we propose two practical approaches for addressing disagreement: (1) filtering out unhelpful biases and (2) capturing legitimate ambiguity through more flexible annotation schemes.
