Discourse Structure for the Minecraft Corpus

AbstractWe provide a new linguistic resource: The Minecraft Structured Dialogue Corpus (MSDC), a discourse annotated version of the Minecraft Dialogue Corpus (MDC; Narayan-Chen et al., 2019), with complete, situated discourse structures in the style of SDRT (Asher and Lascarides, 2003). Our structures feature both linguistic discourse moves and nonlinguistic actions. To show computational tractability, we train a discourse parser with a novel “2 pass architecture” on MSDC that gives excellent results on attachment prediction and relation labeling tasks especially long distance attachments.
