RecSys in HR at ACM RecSys 2022 in Seattle!

📅 April 10, 2022 • 🕐 09:37 • 🏷 Blog and Research

Fantastic news! We’ve received word the 2nd edition of our “Recommender Systems for Human Resources” (RecSys in HR) Workshop has been accepted to be included in the ACM RecSys 2022 program, to be held in Seattle!

Last year’s (first) edition of our workshop was co-located with ACM RecSys 2021 in Amsterdam, and featured two keynotes, a panel, breakout sessions and 8 paper presentations. The recording, workshop proceedings, and a workshop report are available through our workshop’s website at: https://recsyshr2021.aau.dk/

Check back there soon for information on the 2022 edition we’re planning with Toine Bogers, Mesut Kaya, Francisco Gutiérrez, and newly joined co-organizers Sepideh Mesbah (Randstad Groep Nederland) and Chris Johnson (Indeed.com)!

At KINTalks on AI in HR

📅 March 1, 2022 • 🕐 11:21 • 🏷 Blog

I’m giving a talk at the KINTalks series, organized by the KIN Center for Digital Innovation on March 25. It’s going to be a hybrid event, so happy to meet you at the VU Amsterdam, and if not, see you online! RSVP here on EventBrite.

KINTalks is a hybrid event where practitioners are invited to talk about their work experience regarding innovation and digital technology.

The blurb

At Randstad, the global leader in the HR services industry, searching and matching is at the heart of what we do. Being founded in 1960, We know from our heritage that real connections are not made from data and algorithms alone – they require human involvement. Last year, we helped more than two million job seekers find a meaningful job by combining industry-scale recommender and search systems with our distinct human touch. While many opportunities exist, employing AI in recruitment and HR is considered high-risk by the European Commission’s proposed regulatory framework on AI, which will bring additional requirements, obligations, and constraints.

In this hybrid talk, I will explain some of the characteristics of, challenges, and opportunities in the HR domain from an AI perspective. I will share some of our own work in recommendations, algorithmic matching, algorithmic bias and knowledge graphs, and highlight some of the ongoing research in this domain.

Two papers accepted at CompJobs ’22

We have two papers accepted at “The First International Workshop on Computational Jobs Marketplace“, co-located with WSDM 2022. Both papers are based on work done by two of our former thesis interns at Randstad Groep Nederland!

☝️ Ninande Vermeer worked under supervision of Sepideh Mesbah and Vera Provatorova (UvA) on: “Using RobBERT and eXtreme Multi-Label Classification to Extract Implicit and Explicit Skills From Dutch Job Descriptions” in which we study to what extent a RobBERT-XMLC model can be used to extract explicit and implicit skills from Dutch job descriptions.

✌️ Sarah-Jane van Els worked under supervision of myself and Emma Beauxis-Aussalet (Civic AI Lab) on “Improving Fairness Assessments with Synthetic Data: a Practical Use Case with a Recommender System for Human Resources” in which we explore approaches and methods for assessing algorithmic bias by using synthetic data to improve the size and representativity of a test set used for training candidate recommender systems.

👏 Proud of our former interns for having published their work! And happy with the collaborations we have had with our co-authors 😁.

Panel on AI and Inclusivity in the Labor Market

📅 November 10, 2021 • 🕐 10:35 • 🏷 Blog

Update: unfortunately but understandably (in light of the pandemic), this conference has been post-poned until further notice.

December 9th I will join a panel discussion on AI and equal opportunities in the labor market (together with Siri Beerends & Rina Joosten-Rabou), at a conference organized by WOMEN INC. An offline event in Utrecht (Corona volente)!

More details and RSVP (in Dutch) here: Congres | “Hey Siri: Vind een geschikte kandidaat”

RecSys in HR Workshop Recording available

📅 October 29, 2021 • 🕐 12:08 • 🏷 Blog

For those who missed it — like myself 😏 — we have now published the full recording of our Recommender Systems in Human Resources (RecSys in HR) Workshop, which was held on October 1st, in conjunction with the ACM RecSys Conference in Amsterdam.

Our workshop included two keynotes, eight paper presentations, breakout sessions, a virtual panel on the topics of the upcoming EU framework on AI, Fair & inclusive HR Tech, and how to “activate hidden workers.” See the full program here.

So, if you have 4h33m to spare, see the full recording below! 

(or use the convenient YouTube chapter to jump through the program 😅)

Many thanks to all co-organizers, contributors, paper authors, and participants, both virtual and in-person! And hopefully we’ll see each other at the second edition ✌️.

Webinar on governing AI

📅 August 16, 2021 • 🕐 16:57 • 🏷 Blog

Together with Helen Hulsker I joined of a webinar on governing AI by Dataiku, read the blurb here:

There are many obstacles for Data Scientists in effectively governing the use of AI such as, overcoming the bias inherent in historical data, agreeing on the boundaries of governing AI with the business, and perhaps most importantly, ensuring the adoption of good AI practices across the organisation.

So join Randstad and Dataiku as we set the stage around implementing AI in a high-risk domain from a technical/practical and jurisdictional perspective.

Check out the recording at BrightTALK!

Keynote on Data Science in HR at FEAST Workshop (@ ECML-PKDD 2021)

📅 August 9, 2021 • 🕐 09:59 • 🏷 Blog

Excited to be giving a keynote at the International Workshop on Fair, Effective And Sustainable Talent management using data science (FEAST workshop), part of the European Conference on Machine Learning and Principles and Practice of Knowledge Discovery in Databases (ECML PKDD 2021).

I’ll give a talk about some of our recent data science projects Randstad Groep Nederland, spanning from our job/candidate recommender systems, work on bias and bias mitigation, knowledge graphs, and deep embeddings for learning to match candidates to vacancies. 

Forget the Trolley Problem; Pragmatic and Fair AI in the Real World

📅 April 13, 2021 • 🕐 19:07 • 🏷 Blog

Update: my article has been published on TowardsDataScience, selected as an editor’s pick, and highlighted in TowardsDataScience’s weekly newsletter “The Variable”!

The AI doomsday scenarios, ignited by books such as The Filter Bubble (2011) and Weapons of Math Destruction (2016), are slowly being superseded by more pragmatic and nuanced views of AI. Views in which we acknowledge we’re in control of AI and able to design them in ways that reflect values of our choice.

This shift can be seen in the rising involvement of computer scientists, e.g., through books such as The Ethical Algorithm (2019) or Understand, Manage, and Prevent Algorithmic Mitigate Bias (2019), books that describe and acknowledge the challenges and complexities of algorithmic fairness, but at the same time offer concrete methods and tools for more fair and ethical algorithms. This shift can too be seen in that the methods described in these books have already found their ways into the offerings of all major cloud providers, e.g., at the FAccT 2021 Tutorial “Responsible AI in Industry: Lessons Learned in Practice” Microsoft, Google, and Amazon demoed their fair AI solutions to the multidisciplinary audience of the FAccT community.

The message is clear: we can (and should!) operationalize algorithmic fairness.

Co-organizing “RecSys in HR” workshop at RecSys 2021!

📅 March 18, 2021 • 🕐 12:14 • 🏷 Blog and Research

We received news that our workshop proposal “RecSys in HR: Workshop on Recommender Systems for Human Resources” was accepted for inclusion in the 15th ACM Conference on Recommender Systems (RecSys 2021) program! That means we’ll be running a full-day workshop with (research and position) papers, keynotes, and a panel (all TBD) during the conference which will be held in Amsterdam, 27th September-1st October 2021.

We wrote this workshop proposal with Toine Bogers (Aalborg University), Mesut Kaya (Aalborg University), Katrien Verbert (KU Leuven) and Francisco Gutiérrez (KU Leuven), at the initiative/idea of Toine, who virtually approached me in RecSys 2020’s gather.town :-D. Toine and Mesut work on a large research project with Denmark’s largest online recruitment portal, JobIndex.
