Unsupervised Question Answering via Answer Diversifying
Published in COLING 2022, 2022
In this study, we propose a method, called DiverseQA, to tackle the problem of diversifying answers in unsupervised question answering.

Capturing Global Structural Information in Long Document Question Answering with Compressive Graph Selector Network
Published in EMNLP 2022, 2022
In this study, we propose Compressive Graph Selector Network (CGSN) to capture the global structure in a compressive and iterative manner.

AttenWalker: Unsupervised Long-Document Question Answering via Attention-based Graph Walking
Published in ACL 2023 Findings, 2023
In this study, we propose a new task, named unsupervised long-document question answering (ULQA), aiming to generate high-quality long-document QA instances in an unsupervised manner. Besides, we propose AttenWalker, a novel unsupervised method to aggregate and generate answers with long-range dependency so as to construct long-document QA pairs.

Mix-Initiative Response Generation with Dynamic Prefix Tuning
Published in NAACL 2024, 2024
In this work, we propose a general mix-Initiative Dynamic Prefix Tuning framework (IDPT) to decouple different initiatives from the generation model.

Towards Generalizable AI in Medicine via Generalist-Specialist Collaboration
Published in Nature Biomedical Engineering 2026, 2026
In this work, we propose Generalist-Specialist Collaboration (GSCo), a cooperative framework that combines a medical generalist foundation model with lightweight specialist models for more generalizable AI in medicine.
