abstract

We propose an efficient neural framework for sentence-level discourse analysis in accordance with Rhetorical Structure Theory (RST). Our framework comprises a discourse segmenter to identify the elementary discourse units (EDU) in a text, and a discourse parser that constructs a discourse tree in a top-down fashion. Both the segmenter and the parser are based on Pointer Networks and operate in linear time. Our segmenter yields an $F_1$ score of 95.4, and our parser achieves an $F_1$ score of 81.7 on the aggregated labeled (relation) metric, surpassing previous approaches by a good margin and approaching human agreement on both tasks (98.3 and 83.0 $F_1$).

Discussion (0). Continue with ORCID to comment.

  1. Hierarchical Pointer Net Parsing

    cs.CL 2019-08 conditional novelty 6.0 of 10

    A hierarchical pointer-network decoder that conditions on parent and sibling states improves discourse parsing relation F1 to 82.77 and gives marginal dependency parsing gains.
