Joint Syntacto-Discourse Parsing and the Syntacto-Discourse Treebank The source code and the joint treebank are available at https://github.com/kaayy/josydipa.
Table 1: Accuracies on PTB-RST at constituency and discourse levels.

Since our parser essentially performs both constituency parsing task and discourse parsing task. We also evaluate the performances on sentence constituency level and discourse level separately. Note that in constituency level, the accuracy is not directly comparable with the accuracy reported in Cross and Huang , since: a) our parser is trained on a much smaller dataset (RST Treebank is about 1/6 of Penn Treebank); b) the parser is trained to optimize the discourse-level accuracy.
