摘要:

本文提出了我们针对Discharge Me!共享任务的解决方案,该任务与第23届生物医学自然语言处理研讨会(BioNLP)同期举办。在本研究中,我们开发了一个基于LLM的框架来解决出院摘要文档记录(DSD)任务,即生成出院摘要中的两个关键目标部分:“简要住院病程”和“出院指导”。通过简化近期在LLM上的指令微调过程,我们探索了几种提示策略,以将LLM最佳地适配到DSD的特定生成任务中。实验结果表明,提供清晰的输出结构,辅以一套全面的思维链问题,能有效提升模型的推理能力,从而增强生成文本中临床信息的结构正确性和忠实度。源代码可在以下地址获取:https://github.com/antangrocket1312/Discharge_LLM

英文摘要:

This paper presents our proposed approach to the Discharge Me! shared task, collocated with the 23th Workshop on Biomedical Natural Language Processing (BioNLP). In this work, we develop an LLM-based framework for solving the Discharge Summary Documentation (DSD) task, i.e., generating the two critical target sections `Brief Hospital Course' and `Discharge Instructions' in the discharge summary. By streamlining the recent instruction-finetuning process on LLMs, we explore several prompting strategies for optimally adapting LLMs to specific generation task of DSD. Experimental results show that providing a clear output structure, complimented by a set of comprehensive Chain-of-Thoughts (CoT) questions, effectively improves the model's reasoning capability, and thereby, enhancing the structural correctness and faithfulness of clinical information in the generated text.
