The DISRPT 2021 Shared Task on Elementary Discourse Unit Segmentation, Connective Detection, and Relation Classification

no code implementations EMNLP (DISRPT) 2021 Amir Zeldes, Yang Janet Liu, Mikel Iruskieta, Philippe Muller, Chloé Braud, Sonia Badene

In 2021, we organized the second iteration of a shared task dedicated to the underlying units used in discourse parsing across formalisms: the DISRPT Shared Task (Discourse Relation Parsing and Treebanking).

Putting Context in SNACS: A 5-Way Classification of Adpositional Pragmatic Markers

no code implementations LREC (LAW) 2022 Yang Janet Liu, Jena D. Hwang, Nathan Schneider, Vivek Srikumar

The SNACS framework provides a network of semantic labels called supersenses for annotating adpositional semantics in corpora.

eRST: A Signaled Graph Theory of Discourse Relations and Organization

2 code implementations20 Mar 2024 Amir Zeldes, Tatsuya Aoyama, Yang Janet Liu, Siyao Peng, Debopam Das, Luke Gessler

In this article we present Enhanced Rhetorical Structure Theory (eRST), a new theoretical framework for computational discourse analysis, based on an expansion of Rhetorical Structure Theory (RST).

What's Hard in English RST Parsing? Predictive Models for Error Analysis

1 code implementation10 Sep 2023 Yang Janet Liu, Tatsuya Aoyama, Amir Zeldes

Despite recent advances in Natural Language Processing (NLP), hierarchical discourse parsing in the framework of Rhetorical Structure Theory remains challenging, and our understanding of the reasons for this are as yet limited.

GUMSum: Multi-Genre Data and Evaluation for English Abstractive Summarization

1 code implementation20 Jun 2023 Yang Janet Liu, Amir Zeldes

Automatic summarization with pre-trained language models has led to impressively fluent results, but is prone to 'hallucinations', low performance on non-news genres, and outputs which are not exactly summaries.

GENTLE: A Genre-Diverse Multilayer Challenge Set for English NLP and Linguistic Evaluation

1 code implementation3 Jun 2023 Tatsuya Aoyama, Shabnam Behzad, Luke Gessler, Lauren Levine, Jessica Lin, Yang Janet Liu, Siyao Peng, YIlun Zhu, Amir Zeldes

We evaluate state-of-the-art NLP systems on GENTLE and find severe degradation for at least some genres in their performance on all tasks, which indicates GENTLE's utility as an evaluation dataset for NLP systems.

Why Can't Discourse Parsing Generalize? A Thorough Investigation of the Impact of Data Diversity

1 code implementation13 Feb 2023 Yang Janet Liu, Amir Zeldes

To our knowledge, this study is the first to fully evaluate cross-corpus RST parsing generalizability on complete trees, examine between-genre degradation within an RST corpus, and investigate the impact of genre diversity in training data composition.
