Discourse Representation Theory (DRT) is a formal account for representing the meaning of natural language discourse. Meaning in DRT modeled via Structure (DRS), representation with model-theoretic interpretation, which usually depicted as nested boxes. In contrast, directed labeled graph common data structure used to encode semantics texts. The paper describes procedure dressing up DRSs graphs include new framework 2020 shared task on Cross-Framework and Cross-Lingual Parsing. Since one goals encourage unified models several semantic frameworks, conversion was biased towards making somewhat similar other graph-based frameworks.
