Entity-based De-noising Modeling for Controllable Dialogue Summarization

no code implementations SIGDIAL (ACL) 2022 Zhengyuan Liu, Nancy Chen

Although fine-tuning pre-trained backbones produces fluent and grammatically-correct text in various language generation tasks, factual consistency in abstractive summarization remains challenging.

PromptSum: Parameter-Efficient Controllable Abstractive Summarization

no code implementations6 Aug 2023 Mathieu Ravaut, Hailin Chen, Ruochen Zhao, Chengwei Qin, Shafiq Joty, Nancy Chen

Prompt tuning (PT), a parameter-efficient technique that only tunes the additional prompt embeddings while keeping the backbone pre-trained language model (PLM) frozen, has shown promising results in language understanding tasks, especially in low-resource scenarios.

Unsupervised Summarization Re-ranking

2 code implementations19 Dec 2022 Mathieu Ravaut, Shafiq Joty, Nancy Chen

With the rise of task-specific pre-training objectives, abstractive summarization models like PEGASUS offer appealing zero-shot performance on downstream summarization tasks.

Taking Quantitative Genomics into the Wild

no code implementations26 Sep 2022 Susan E. Johnston, Nancy Chen, Emily B. Josephs

A key goal in studies of ecology and evolution is understanding the causes of phenotypic diversity in nature.

Uncertainty Modeling for Machine Comprehension Systems using Efficient Bayesian Neural Networks

no code implementations COLING 2020 Zhengyuan Liu, Pavitra Krishnaswamy, Ai Ti Aw, Nancy Chen

While neural approaches have achieved significant improvement in machine comprehension tasks, models often work as a black-box, resulting in lower interpretability, which requires special attention in domains such as healthcare or education.

Exploiting Discourse-Level Segmentation for Extractive Summarization

no code implementations WS 2019 Zhengyuan Liu, Nancy Chen

We investigate how the sub-sentential segmentation improves extractive summarization performance when content selection is modeled through two basic neural network architectures and a deep bi-directional transformer.

Set to Ordered Text: Generating Discharge Instructions from Medical Billing Codes

no code implementations IJCNLP 2019 Litton J Kurisinkel, Nancy Chen

This task differs from other natural language generation tasks in the following ways: (1) The input is a set of identifiable entities (ICD codes) where the relations between individual entity are not explicitly specified.

Acoustic Characterization of Singaporean Children's English: Comparisons to American and British Counterparts

no code implementations WS 2019 Yuling Gu, Nancy Chen

We investigate English pronunciation patterns in Singaporean children in relation to their American and British counterparts by conducting archetypal analysis on selected vowel pairs.

Isolating the Effects of Modeling Recursive Structures: A Case Study in Pronunciation Prediction of Chinese Characters

no code implementations WS 2019 Minh Nguyen, Gia H. Ngo, Nancy Chen

Finding that explicitly modeling structures leads to better generalization, we consider the task of predicting Cantonese pronunciations of logographs (Chinese characters) using logographs{'} recursive structures.

Reading Turn by Turn: Hierarchical Attention Architecture for Spoken Dialogue Comprehension

no code implementations ACL 2019 Zhengyuan Liu, Nancy Chen

Comprehending multi-turn spoken conversations is an emerging research area, presenting challenges different from reading comprehension of passages due to the interactive nature of information exchange from at least two speakers.
