Gauri Naik, Sharad Chandakacherla, Shweta Yadav, Md. Shad Akhtar

TL;DR
This paper introduces a new perspective-aware summarization task for healthcare community Q&A forums, proposing a novel dataset and a controllable summarization model that outperforms existing baselines.
Contribution
It presents the first perspective-specific summarization framework for healthcare answers, including a new annotated dataset and a prompt-driven model with energy-controlled optimization.
Findings
PLASMA outperforms five baselines with 1.5-21% improvement.
The PUMA dataset contains 3167 threads with 6193 perspective-aware summaries.
Ablation and qualitative analyses validate the effectiveness of the proposed approach.
Abstract
Healthcare Community Question Answering (CQA) forums offer an accessible platform for individuals seeking information on various healthcare-related topics. People find such platforms suitable for self-disclosure, seeking medical opinions, finding simplified explanations for their medical conditions, and answering others' questions. However, answers on these forums are typically diverse and prone to off-topic discussions. It can be challenging for readers to sift through numerous answers and extract meaningful insights, making answer summarization a crucial task for CQA forums. While several efforts have been made to summarize the community answers, most of them are limited to the open domain and overlook the different perspectives offered by these answers. To address this problem, this paper proposes a novel task of perspective-specific answer summarization. We identify various…
