AI总结:

本文评估八种零样本 LLM 在系统综述摘要筛选中的效果,提出基于召回率阈值的校准方法,并通过五个标准测试集证明指令微调、校准与模型集成可在保证目标召回率的同时显著节省筛选时间。

摘要:

系统综述对于循证医学至关重要,因为它们会全面分析针对特定问题已发表的研究发现。开展此类综述通常耗费大量资源与时间,尤其是在筛选阶段,需要评估出版物摘要以决定是否将其纳入综述。本研究考察了使用零样本大语言模型(LLM)进行自动筛选的有效性。我们评估了八种不同 LLM 的有效性,并研究了一种校准技术,该技术使用预定义的召回率阈值来确定某篇出版物是否应被纳入系统综述。我们使用五个标准测试集进行的综合评估表明:指令微调和筛选发挥重要作用;校准使 LLM 能够实际实现目标召回率;而将两者与零样本模型集成相结合,与最先进方法相比可显著节省筛选时间。

英文摘要:

Systematic reviews are crucial for evidence-based medicine as they comprehensively analyse published research findings on specific questions. Conducting such reviews is often resource- and time-intensive, especially in the screening phase, where abstracts of publications are assessed for inclusion in a review. This study investigates the effectiveness of using zero-shot large language models~(LLMs) for automatic screening. We evaluate the effectiveness of eight different LLMs and investigate a calibration technique that uses a predefined recall threshold to determine whether a publication should be included in a systematic review. Our comprehensive evaluation using five standard test collections shows that instruction fine-tuning plays an important role in screening, that calibration renders LLMs practical for achieving a targeted recall, and that combining both with an ensemble of zero-shot models saves significant screening time compared to state-of-the-art approaches.
