  Rhetorical Structure Theory based Discourse Parsing (RST-DP) explores how
clauses, sentences, and large text spans compose a whole discourse and presents
the rhetorical structure as a hierarchical tree. Existing RST parsing pipelines
construct rhetorical structures without the knowledge of document-level content
structures, which causes relatively low performance when predicting the
discourse relations for large text spans. Recognizing the value of high-level
content-related information in facilitating discourse relation recognition, we
propose a novel pipeline for RST-DP that incorporates structure-aware news
content sentence representations derived from the task of News Discourse
Profiling. By incorporating only a few additional layers, this enhanced
pipeline exhibits promising performance across various RST parsing metrics.
