检测大模型在简历匹配中对性别、种族和教育背景的隐性偏见。
Evaluating Bias in LLMs for Job-Resume Matching: Gender, Race, and Education
- 在英文美国语境下测试大模型的招聘匹配公平性。
- 显性偏见（性别/种族）已减少，但教育背景隐性偏见仍严重。
- 适合关注AI招聘公平性的企业与研究者参考。
大型语言模型（LLMs）有望通过自动匹配职位描述与候选人简历来实现招聘自动化，提升流程效率并降低运营成本。然而，模型固有的偏见可能导致不公平的招聘行为，加剧社会偏见并损害职场多样性。本研究评估了英文语境下美国场景中大模型在职位-简历匹配任务中的表现与公平性，分析性别、种族及教育背景等因素对模型决策的影响，揭示其在人力资源应用中的可靠性与公正性。结果表明，尽管近期模型在性别和种族等显性属性上的偏见有所缓解，但与教育背景相关的隐性偏见依然显著。研究强调需持续评估并发展先进的偏见缓解策略，以确保工业应用中大模型支持公平招聘。
原文摘要 · Abstract (English)
Large Language Models (LLMs) offer the potential to automate hiring by matching job descriptions with candidate resumes, streamlining recruitment processes, and reducing operational costs. However, biases inherent in these models may lead to unfair hiring practices, reinforcing societal prejudices and undermining workplace diversity. This study examines the performance and fairness of LLMs in job-resume matching tasks within the English language and U.S. context. It evaluates how factors such as gender, race, and educational background influence model decisions, providing critical insights into the fairness and reliability of LLMs in HR applications. Our findings indicate that while recent models have reduced biases related to explicit attributes like gender and race, implicit biases concerning educational background remain significant. These results highlight the need for ongoing evaluation and the development of advanced bias mitigation strategies to ensure equitable hiring practices when using LLMs in industry settings.
