[ACL 2022] Rethinking Self-Supervision Objectives for Coherence Modeling

Prathyusha Jwalapuram, Shafiq Joty, Xiang Lin

We build a generalizable coherence model that performs well on several downstream tasks by using contrastive training and a large global negative sample queue encoded by a momentum encoder.

[EACL 2021] Rethinking Coherence Modeling: Synthetic vs. Downstream Tasks

Tasnim Mohiuddin, Prathyusha Jwalapuram, Xiang Lin, Shafiq Joty

We conduct experiments on benchmarking well-known traditional and neural coherence models on synthetic sentence ordering tasks, and contrast this with their performance on three downstream applications: coherence evaluation for MT and summarization, and next utterance prediction in retrieval-based dialog.

[ACL 2019] A Unified Linear-Time Framework for Sentence-Level Discourse Parsing

Xiang Lin, Shafiq Joty, Prathyusha Jwalapuram, M Saiful Bari

We propose an efficient neural framework for sentence-level discourse analysis in accordance with Rhetorical Structure Theory (RST).
