本文提出属性结构化框架,将临床文本摘要评估分解为简单任务,提升LLM评估与人工标注一致性,并支持高效审计。

摘要:

总结临床文本对于健康决策支持和临床研究至关重要。大型语言模型(LLMs)已展现出生成准确临床文本摘要的潜力,但在基础性和评估方面仍存在问题,尤其是在健康等安全关键领域。整体评估文本摘要具有挑战性,因为摘要可能包含未经证实的信息。在此,我们探索了一种使用属性结构化(AS)的通用缓解框架,该框架对摘要评估过程进行结构化。它将评估过程分解为一个基于证据的程序,利用LLM执行相对简单的结构化和评分任务,而非整体摘要评估的完整任务。实验表明,AS在临床文本摘要中持续改善了人工标注与自动化指标之间的一致性。此外,AS以对应每个输出的短文本片段形式提供解释,从而支持高效的人工审计,为在资源受限场景中可信评估临床信息铺平了道路。我们在https://github.com/microsoft/attribute-structuring发布了代码、提示词和一个开源基准。

英文摘要:

Summarizing clinical text is crucial in health decision-support and clinical research. Large language models (LLMs) have shown the potential to generate accurate clinical text summaries, but still struggle with issues regarding grounding and evaluation, especially in safety-critical domains such as health. Holistically evaluating text summaries is challenging because they may contain unsubstantiated information. Here, we explore a general mitigation framework using Attribute Structuring (AS), which structures the summary evaluation process. It decomposes the evaluation process into a grounded procedure that uses an LLM for relatively simple structuring and scoring tasks, rather than the full task of holistic summary evaluation. Experiments show that AS consistently improves the correspondence between human annotations and automated metrics in clinical text summarization. Additionally, AS yields interpretations in the form of a short text span corresponding to each output, which enables efficient human auditing, paving the way towards trustworthy evaluation of clinical information in resource-constrained scenarios. We release our code, prompts, and an open-source benchmark at https://github.com/microsoft/attribute-structuring.
