AI总结:

本文提出医学文本生成细粒度评估框架DocLens,从完整性、简洁性和归因性三方面评估生成文本,并在三个医学任务上验证其与专家判断的高度一致性。

摘要:

医学文本生成旨在辅助行政工作并突出关键信息以支持决策。为反映医学文本的具体要求,本文提出一组指标,在细粒度层面评估生成文本的完整性、简洁性和归因性。这些指标可由多种类型的评估器计算,包括遵循指令的模型(专有和开源)以及监督蕴含模型。我们通过三个评估器在三个任务上展示了所构建框架DocLens的有效性:临床笔记生成、放射学报告摘要和患者问题摘要。一项全面的人工研究表明,与现有指标相比,DocLens与医学专家判断的一致性显著更高。结果还凸显了改进开源评估器的必要性,并提出了潜在方向。

英文摘要:

Medical text generation aims to assist with administrative work and highlight salient information to support decision-making. To reflect the specific requirements of medical text, in this paper, we propose a set of metrics to evaluate the completeness, conciseness, and attribution of the generated text at a fine-grained level. The metrics can be computed by various types of evaluators including instruction-following (both proprietary and open-source) and supervised entailment models. We demonstrate the effectiveness of the resulting framework, DocLens, with three evaluators on three tasks: clinical note generation, radiology report summarization, and patient question summarization. A comprehensive human study shows that DocLens exhibits substantially higher agreement with the judgments of medical experts than existing metrics. The results also highlight the need to improve open-source evaluators and suggest potential directions.
