AI总结:

本研究推出符合隐私规范的真实职位推荐公平性数据集FairJob,提出敏感属性代理方案与公平效用指标计算方法,实验验证了偏差缓解技术的公平性提升效果及效用权衡。

摘要:

我们推出了一个面向广告场景下职位推荐的公平性感知数据集,旨在推动真实场景中算法公平性的研究。该数据集的收集与制备均符合隐私标准与商业保密要求。研究面临的另一项挑战是无法获取性别等受保护的用户属性,对此我们提出了一种获取代理估计值的解决方案。尽管经过匿名化处理且包含敏感属性的代理变量,我们的数据集仍保留了预测能力,可作为一个兼具真实性与挑战性的基准。该数据集填补了广告等高影响领域中以公平性为核心的资源缺口——此类场景的实际影响关乎用户能否获得宝贵的就业机会,而平衡公平性与效用是行业普遍面临的难题。我们还探究了广告流程中可能出现不公平现象的各个阶段,并提出了一种方法,可基于有偏数据集计算在线系统职位推荐场景下的公平效用指标。在发布的数据集上对偏差缓解技术开展的实验评估,验证了公平性提升的潜力以及其与效用之间的权衡关系。该数据集托管于https://huggingface.co/datasets/criteo/FairJob,实验源代码托管于https://github.com/criteo-research/FairJob-dataset/。

英文摘要:

We introduce a fairness-aware dataset for job recommendations in advertising, designed to foster research in algorithmic fairness within real-world scenarios. It was collected and prepared to comply with privacy standards and business confidentiality. An additional challenge is the lack of access to protected user attributes such as gender, for which we propose a solution to obtain a proxy estimate. Despite being anonymized and including a proxy for a sensitive attribute, our dataset preserves predictive power and maintains a realistic and challenging benchmark. This dataset addresses a significant gap in the availability of fairness-focused resources for high-impact domains like advertising -- the actual impact being having access or not to precious employment opportunities, where balancing fairness and utility is a common industrial challenge. We also explore various stages in the advertising process where unfairness can occur and introduce a method to compute a fair utility metric for the job recommendations in online systems case from a biased dataset. Experimental evaluations of bias mitigation techniques on the released dataset demonstrate potential improvements in fairness and the associated trade-offs with utility. The dataset is hosted at https://huggingface.co/datasets/criteo/FairJob. Source code for the experiments is hosted at https://github.com/criteo-research/FairJob-dataset/.
