Center node: "fast rhetorical structure theory discourse parsing"
  Abstract: Author(s): Heilman, Michael; Sagae, Kenji | Abstract: In recent years, There has been a variety of research on discourse parsing, particularly RST discourse parsing. Most of the recent work on RST parsing has focused on implementing new types of features or learning algorithms in order to improve accuracy, with relatively little focus on efficiency, robustness, or practical use. Also, most implementations are not widely available. Here, we describe an RST segmentation and parsing system that adapts models and feature sets from various previous work, as described below. Its accuracy is near state-of-the-art, and it was developed to be fast, robust, and practical. For example, it can process short documents such as news articles or essays in less than a second.

Connected through hyperedge HE-1 (induced by source paper "joint syntacto discourse parsing and the syntacto discourse treebank"):
  with members:
    - "neural net models for open domain discourse coherence"
    - "incremental parsing with minimal features using bi directional lstm"
    - "better document level sentiment analysis from rst discourse parsing"
