中文简介:
LinkedIn 等在线专业社交网络充当市场,求职者可以在其中找到合适的职业机会,工作提供者可以接触潜在的候选人。LinkedIn 的职位推荐产品是潜在候选人和职位发布之间高效匹配的关键工具。然而,我们在实践中观察到,一部分职位发布收到的申请过多(由于公司知名度、工作性质等多种原因),而其他一些职位发布收到的申请过少。这两种情况都可能导致招聘海报不满意,并可能导致相关招聘合同终止。同时,如果过多的求职者竞争同一个职位,每个求职者获得这份工作的机会就会减少。在长期,这减少了用户在网站上找到他们真正喜欢的工作的机会。因此,职位推荐系统考虑向求职者以及市场上的职位发布者提供的价值变得有益。 在本文中,我们提出了职位申请重新分配问题,目的是确保职位发布不会收到太多或太少的申请,同时仍然向具有相同相关性的用户提供职位推荐。我们提出了一个动态预测模型来估计职位到期日时的预期申请数量,以及根据预测模型的输出来晋升或惩罚职位的算法。我们还描述了 LiJAR(LinkedIn 的职位申请预测和重新分配系统)的系统设计和架构,我们已在生产中实施和部署了该系统。我们通过离线和在线 A/B 测试实验对 LiJAR 进行广泛的评估。
课程简介: Online professional social networks such as LinkedIn serve as a marketplace, wherein job seekers can find right career opportunities and job providers can reach out to potential candidates. LinkedIn’s job recommendations product is a key vehicle for efficient matching between potential candidates and job postings. However, we have observed in practice that a subset of job postings receive too many applications (due to several reasons such as the popularity of the company, nature of the job, etc.), while some other job postings receive too few applications. Both cases can result in job poster dissatisfaction and may lead to discontinuation of the associated job posting contracts. At the same time, if too many job seekers compete for the same job posting, each job seeker’s chance of getting this job will be reduced. In the long term, this reduces the chance of users finding jobs that they really like on the site. Therefore, it becomes beneficial for the job recommendation system to consider values provided to both job seekers as well as job posters in the marketplace. In this paper we propose the job application redistribution problem, with the goal of ensuring that job postings do not receive too many or too few applications, while still providing job recommendations to users with the same level of relevance. We present a dynamic forecasting model to estimate the expected number of applications at the job expiration date, and algorithms to either promote or penalize jobs based on the output of the forecasting model. We also describe the system design and architecture for LiJAR, LinkedIn’s Job Applications Forecasting and Redistribution system, which we have implemented and deployed in production. We perform extensive evaluation of LiJAR through both offline and online A/B testing experiments. Our production deployment of this system as part of LinkedIn’s job recommendation engine has resulted in significant increase in the engagement of users for underserved jobs (6.5%) without affecting the user engagement in terms of the total number of job applications, thereby addressing the needs of job seekers as well as job providers simultaneously.
