The job panorama in the US is altering dramatically: The COVID-19 pandemic has redefined important work and pushed employees out of the workplace. New applied sciences are altering the character of many professions. Globalization continues to push jobs to new areas. And issues about local weather change are creating jobs within the various vitality sector whereas diverting them from the fossil gas trade.
Amid this office turmoil, employees, employers, and policymakers alike may benefit from understanding which job traits drive higher wages and mobility, says Sarah Bana, a postdoctoral researcher at Stanford’s Digital Economic system Lab, a part of the Stanford Institute for Human-Centered Synthetic Intelligence. And she or he notes that there’s now a big information set that would assist convey this understanding: the textual content of thousands and thousands of on-line job postings.
“On-line information provides us an amazing alternative to measure what issues,” she says.
Actually, utilizing synthetic intelligence (AI) and machine studying, Bana lately confirmed that the phrases utilized in a dataset of greater than one million on-line job postings clarify 87% of the pay hole throughout a big chunk of the job market. It’s the first work to make use of such a big dataset of postings and look at the connection between postings and salaries.

Bana additionally experimented with including new textual content to related job postings—for instance, including a qualification certificates—to see how these phrases modified the wage prediction.
“It seems that we are able to use the textual content of job adverts to evaluate the wage traits of jobs in close to real-time,” says Bana. “This info may make making use of for jobs extra clear and enhance our method to coaching and creating the workforce.”
An AI dataset of 1 million job postings
To investigate how the textual content of on-line job postings pertains to salaries, Bana acquired greater than one million pre-pandemic job postings from Greenwich.HR, which aggregates thousands and thousands of job postings from on-line job boards.
She then used BERT, probably the most superior pure language processing (NLP) fashions obtainable, to coach an NLP mannequin on the textual content of greater than 800,000 job postings and their related wage information. When she examined the mannequin with the remaining 200,000 job openings, it precisely predicted the related salaries 87% of the time. As compared, utilizing solely the job titles and geographic areas of the job postings resulted in correct predictions solely 69% of the time.
Within the follow-up work, Bana will try and characterize the contribution of various phrases to wage prediction. “Ideally, we colour phrases inside job postings from crimson to inexperienced, with the darker crimson phrases being related to decrease wage and the darker inexperienced with higher wage,” she says.
The value of continuous training: A textual content injection experiment
To find out which expertise are vital for wage forecasting, Bana used a textual content injection method: to sure related job postings, she added brief sentences that prompt the job required a selected profession certification, reminiscent of (And the way to obtain it). Acquiring these certifications could be costly, with costs starting from about $225 to about $2,000. Nevertheless, it’s not but attainable to evaluate whether or not the funding is worth it from a wage perspective.
Bana’s experiment discovered that some certifications (just like the IIBA Agile Evaluation Certification) result in vital wage will increase shortly, whereas others (just like the Cisco Licensed Internetwork Knowledgeable) achieve this extra slowly – worthwhile info for employees who would love higher info on how Investing in expertise will have an effect on their salaries and prospects, Bana says.
It isn’t simply workers who profit from this info, Bana notes. Employers can use these outcomes to raised spend money on human capital, she says. For instance, if machine studying fashions present a gradual shift from some duties to others, employers would have advance warning and will reskill particular workers.
And policymakers pondering which VET applications to fund would equally profit from understanding which expertise are rising or lowering in financial value.
To this finish, Bana and her colleagues are at the moment engaged on an accompanying paper that reveals which duties will disappear from the job presents over time and which new duties will probably be added.
Bana hopes that sooner or later, textual evaluation of job postings may result in a web-based software the place employees or corporations may analysis the added value of upskilling or transferring to a brand new geographic location.
“At present, there is not a lot readability concerning the path to higher income,” says Bana. “Instruments like these may assist jobseekers enhance their job prospects, assist employers develop their workforce, and assist policymakers reply to quick shifts within the financial system.”
