AI总结:

针对职位描述信息缺失及其与用户技能分布的异构鸿沟,提出 JobFormer,用语义增强 Transformer 和两阶段技能感知学习提升职位推荐与 CTR 预测效果。

摘要:

职位推荐旨在为潜在人才提供与其职业轨迹相符的合适职位描述(JDs),在主动人才招聘中发挥着重要作用。在现实管理场景中,可用的 JD-用户记录通常由 JD、用户画像和点击数据组成,其中出于隐私原因,用户画像通常被概括为用户的技能分布。尽管现有的先进推荐方法可以直接使用,但考虑到 JD 自身的信息缺失以及 JD 与用户画像之间天然的异构鸿沟,实现有效推荐仍面临挑战。为应对这些挑战,我们提出了一种新颖的技能感知推荐模型,该模型基于所设计的语义增强 Transformer 来解析 JD 并完成个性化职位推荐。具体而言,我们首先对每个 JD 的相关条目进行建模,然后采用带有局部-全局注意力机制的编码器,以更好地从 JD 元组中挖掘职位内和职位间的依赖关系。此外,我们采用两阶段学习策略进行技能感知推荐:在召回阶段利用技能分布指导 JD 表示学习,随后在排序阶段结合用户画像进行最终预测。因此,我们能够为学习 JD 嵌入丰富的上下文语义表示,同时技能感知推荐为点击率(CTR)预测提供有效的 JD-用户联合表示。为验证我们的方法在职位推荐中的优越性能,我们在大规模真实数据集和公开数据集上进行了全面的实证分析,以证明其有效性和可解释性。

英文摘要:

Job recommendation aims to provide potential talents with suitable job descriptions (JDs) consistent with their career trajectory, which plays an essential role in proactive talent recruitment. In real-world management scenarios, the available JD-user records always consist of JDs, user profiles, and click data, in which the user profiles are typically summarized as the user's skill distribution for privacy reasons. Although existing sophisticated recommendation methods can be directly employed, effective recommendation still has challenges considering the information deficit of JD itself and the natural heterogeneous gap between JD and user profile. To address these challenges, we proposed a novel skill-aware recommendation model based on the designed semantic-enhanced transformer to parse JDs and complete personalized job recommendation. Specifically, we first model the relative items of each JD and then adopt an encoder with the local-global attention mechanism to better mine the intra-job and inter-job dependencies from JD tuples. Moreover, we adopt a two-stage learning strategy for skill-aware recommendation, in which we utilize the skill distribution to guide JD representation learning in the recall stage, and then combine the user profiles for final prediction in the ranking stage. Consequently, we can embed rich contextual semantic representations for learning JDs, while skill-aware recommendation provides effective JD-user joint representation for click-through rate (CTR) prediction. To validate the superior performance of our method for job recommendation, we present a thorough empirical analysis of large-scale real-world and public datasets to demonstrate its effectiveness and interpretability.
