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.

基于修辞结构理论的话语解析（RST-DP）探索了子句、句子和大文本跨度如何组成整个话语，并将修辞结构呈现为一个分层树。现有的 RST 解析流水线在构建修辞结构时缺乏对文档级内容结构的了解，导致在预测大文本跨度的话语关系时性能相对较低。为了识别高级内容相关信息在促进话语关系识别方面的价值，我们提出了一种新颖的 RST-DP 流水线，该流水线结合了从新闻话语建模任务中得出的具有结构意识的新闻内容句子表示。通过仅添加了少量的附加层，这个增强的流水线在各种 RST 解析指标上表现出了很有前景的性能。
