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 3: Experiments using gold segmentations. The column of “syntactic feats” shows how the syntactic features are calculated in the corresponding systems. Note that our parser predicts solely based on the span features from bi-directionaly LSTM, instead of any explicitly designed syntactic features.
['human annotation (Ji and Eisenstein,  2014 )', 'human annotation (Ji and Eisenstein,  2014 )', 'syntactic feats -', 'structure 88.7', '+nuclearity 77.7', '+relation 65.8']
On the other hand, the majority of the conventional discourse parsers are not end-to-end: they rely on gold EDU segmentations and pre-trained tools like Stanford parsers to generate features. , so their performances are actually not directly comparable to the results we reported.
