Welcome to The AAAI Workshop on Computational Jobs Marketplace to be held as part of The 39th Annual AAAI Conference on Artificial Intelligence.

Online job marketplaces such as Indeed.com, ZipRecruiter, CareerBuilder and LinkedIn Inc. help millions of job seekers find their next job. These platforms also provide services for thousands of employers to fill their opening positions. With all players in the ecosystem, the market size of this industry is projected to steadily grow and reach $43 billion dollars in 2027. On top of that, the global pandemic COVID-19 in 2020 and the emerging AI trends have profoundly transformed workplaces and the online jobs marketplace, creating and driving new types of jobs and marketplace technologies around the world. Today, online job marketplaces play a central role in this new wave of digital revolution of workforce and workplaces. While this industry generates tremendous growth in the past several years, technological innovations around this industry have yet to come. Many technologies, such as search systems, recommender systems as well as advertising systems that the industry heavily relies on are deeply rooted in their more generic counterparts, which may not address the unique challenges in this industry for better products serving both job seekers and employers/recruiters.

This workshop would play a critical role to bring together the research and development community in this industry especially around data science and machine learning and facilitate innovations on theories, models, systems and practices in this currently scattered community. An expected outcome of the workshop is to create awareness of this emerging industry with its technological opportunities and challenges, which might foster future research and development, creating novel products to serve future job seekers and employers/recruiters.

Talk Title: Emerging Challenges for Recruiting AI

Abstract: This talk will explore some of the ways that the AI problems at the core of the talent marketplace are changing, opening up new areas of research and application. Using the ongoing evolution of LinkedIn’s Recruiter product experience from a classical search engine to a hiring assistant as a case study, we will examine some of these newer AI problems, relate them to other academic research areas, and discuss how the community can collaborate and share knowledge going forward.

Short Bio: Daniel Hewlett is a Principal Staff AI Engineer at LinkedIn, focused on developing the AI capabilities underlying LinkedIn’s new Hiring Assistant, an agent supporting the needs of hirers within the talent marketplace. Previously, Daniel worked in the NLP group at Google Research, and at YouTube, after receiving his Ph.D. in Computer Science from the University of Arizona in 2011. Daniel has contributed to publications at conferences including AAAI, ACL, and KDD.

Talk Title: Ordered Network Embedding and its Potential Applications in Online Job Marketplaces

Abstract: Node embedding is a well-studied research topic with numerous proposed methods derived from matrix factorization to graph neural networks. All the proposed methods attempt to preserve pairwise node proximity in the embedding space, where the proximity is measured based on graph topology or node features. The proximity metrics are generally symmetric, which limits the existing methods to consider undirected networks only. However, in real-life many networks are ordered, and existing embedding methods are not good fit for representing nodes of such networks. For instance, in the job marketplace domain, we use job transition network to generate future job recommendation, but a job transition network is directional, and ignoring such direction for embedding the job vectors may generate poor job recommendation. In this talk, I will give a brief overview of existing methodologies of ordered network embedding followed by a presentation of BINDER, a very efficient method for embedding ordered networks that we have proposed.
