论文摘要

COVID-19的传播导致了许多公司办事处的全球关闭,并鼓励公司开放更多的机会,使员工可以从偏远地区工作。随着工作场所类型从现场办公室扩展到偏远地区,在线招聘市场的新兴挑战是如何在没有事先信息的情况下对这些遥远的机会和用户意图进行远程工作和匹配。尽管在Covid-19中发布了前所未有的远程作业,但没有直接应用现有的方法。 引入全新的工作场所类型自然会导致寒冷的问题,这对于较不活跃的求职者而言尤其普遍。如果现有信息源可以提供与新的工作类别相关的信息,包括简历和作业描述的数据,则在任何预测模型上加入新的工作场所类型是具有挑战性的。因此,在这项工作中,我们旨在提出一种有原则的方法,该方法共同对求职者和工作机会的偏远方式进行了有限的信息,这也足以满足网络规模应用程序的需求。考虑到冷启动和信息稀缺的问题,现有关于新兴远程工作场所类型的研究主要集中在定性研究上,而经典的预测建模方法是不适用的。我们精确地试图通过一种新颖的图神经结构来缩小这一差距。已经进行了来自现实世界应用的大规模数据的广泛实验,以验证拟议方法的优越性,而不是竞争基线。改进可能会转化为新的工作场所类型的更快入门,该类型可以使对远程工作感兴趣的求职者受益。

The spread of COVID-19 leads to the global shutdown of many corporate offices, and encourages companies to open more opportunities that allow employees to work from a remote location. As the workplace type expands from onsite offices to remote areas, an emerging challenge for an online hiring marketplace is how these remote opportunities and user intentions to work remotely can be modeled and matched without prior information. Despite the unprecedented amount of remote jobs posted amid COVID-19, there is no existing approach that can be directly applied. Introducing a brand new workplace type naturally leads to the cold-start problem, which is particularly more common for less active job seekers. It is challenging, if not impossible, to onboard a new workplace type for any predictive model if existing information sources can provide little information related to a new category of jobs, including data from resumes and job descriptions. Hence, in this work, we aim to propose a principled approach that jointly models the remoteness of job seekers and job opportunities with limited information, which also suffices the needs of web-scale applications. Existing research on the emerging type of remote workplace mainly focuses on qualitative studies, and classic predictive modeling approaches are inapplicable considering the problem of cold-start and information scarcity. We precisely try to close this gap with a novel graph neural architecture. Extensive experiments on large-scale data from real-world applications have been conducted to validate the superiority of the proposed approach over competitive baselines. The improvement may translate to more rapid onboarding of the new workplace type that can benefit job seekers who are interested in working remotely.
