Labour Market: a Language Gap I like programming, but I’m interested do take on more project management responsibility Is there a job in our organisation that better fits my degree? We are looking to hire: I’d like to work on our mobile strategy. I’ve helped a friend An experienced tech team team lead develop a mobile app. The ideal candidate has: I’d like to do more with my organisational - min. 5yr of experience talent. - Certfied scrummaster - Exp. w/iOS, Android Completed academic studies Computer Science or related 30% travel for customer presentations
Why? In the next 5-10 years, AI will reach a level of near or super human performance in many domains, including understanding language and connecting supply and demand. AI will fundamentally change the way people and jobs connect in the global marketplace, and will remove market barriers caused by language meaning variation and lack of transparency. What will this mean to recruiters and job seekers?
What do recruiters do? Attracting Processing Selecting Chasing Line candidates candidates candidates Managers Employer Branding Data Entry Interviews WTF?! Advertising Screening Assessment Understanding Re-engagement Job offers the job Scheduling Contracts Scoring Referral Sourcing Basic information AI Revolution: lowers the cost of repetitive cognitive tasks...
AI: The miracle algorithm?
Right candidate, right time, right price!
So what if you have technology that actually understands : • the real requirements of the job • the key factors to be successful • the type of person most likely to succeed • what your offer should be
So what do we mean by AI?

What does Machine Learning give us? Ability to solve problems with unknown rules
What does Machine Learning give us? Pattern discovery in volumes of data no human being is able to digest
What does Machine Learning give us? Optimize solutions to problems with any value that we can define
What does Machine Learning give us? Any human behavior for which we can collect sufficient data can be automated by AI / Machine Learning
AI is Mainstream
Why now? Computing power, data, algorithms Deep Learning
Deep Learning is the ability for AI algorithms to automatically learn meaningful patterns in data using layered brain-like structures called Deep Neural Networks
Deep Learning: Hierarchically abstract information Use lots of unlabeled data • Deep multi-layered networks • Automatically finds relevant features •
Understanding, connecting and analyzing people and jobs
Given a job, how do we find the relevant candidates for the job among thousands or millions of CV’s?

Example of Matching
Turning the job description into a rich query
Learning from Feedback: • Which candidate is the best? • Which criterion is more important? • How about combination of criteria? • How about domain biases? • What if we can learn this automatically from feedback? • Learning to Rank • Reorder a pool of candidates through machine learning • E.g. Based on recruiter preference or past performance
