Papers with discourse parser
Evaluating Discourse in Structured Text Representations (P19-1)
Copied to clipboard
| Challenge: | Discourse structure is integral to understanding a text and is useful in many NLP tasks. |
| Approach: | They propose a structured attention mechanism for text classification that derives a tree over a text, akin to an RST discourse tree. |
| Outcome: | The proposed model improves performance on multiple discourse-relevant tasks and datasets and ablation studies show it does little to capture discourse structure. |
Predicting Discourse Structure using Distant Supervision from Sentiment (D19-1)
Copied to clipboard
| Challenge: | Discourse parsing is a fundamental NLP task known to enhance key downstream tasks, such as sentiment analysis, text classification and summarization. |
| Approach: | They propose a method that uses document supervision to generate abundant data for RST-style discourse structure prediction by using an optimal CKY-style tree generation algorithm. |
| Outcome: | The proposed approach performs well on the more difficult task of inter-domain discourse structure prediction, but it does not match the performance of a parser trained and tested on the same dataset. |
A Unified Linear-Time Framework for Sentence-Level Discourse Parsing (P19-1)
Copied to clipboard
| Challenge: | a new neural framework for sentence-level discourse analysis is proposed . a discourse segmenter and a parser are based on pointer networks and operate in linear time . |
| Approach: | They propose a neural framework for sentence-level discourse analysis in accordance with Rhetorical Structure Theory . they use a discourse segmenter and a parser to construct a discursive tree in a top-down fashion . |
| Outcome: | The proposed framework surpasses previous approaches on both tasks and human agreement on both. |
Discourse Structure for the Minecraft Corpus (2024.lrec-main)
Copied to clipboard
| Challenge: | a discourse annotated version of the Minecraft Dialogue Corpus is a new linguistic resource for human-computer interaction . a recent study shows that inferring excecutable actions from language is difficult in the Minecraft setting . |
| Approach: | They propose a discourse annotated version of the Minecraft Dialogue Corpus . they train a parser with a novel "2 pass architecture" that gives excellent results . |
| Outcome: | The proposed model performs well on attachment prediction and relation labeling tasks especially long distance attachments. |
