1. Jobs in tech, manufacturing, and engineering are more exposed to AI; HR, public service, and legal sectors are less exposed
2. Exposure to AI shows distinct association patterns regarding offered salary depending on the industry sectors (4/5)
In the information industry sector, our wAII is “positively” associated with offered salary. On the other hand, in the wholesale trade industry sector, wAII is “negatively” associated with offered salary.

To track this, we developed the Weighted AI Index (wAII), a scalable method to measure how closely a job’s tasks align with recent AI innovations.
We extract key job tasks from postings; compare them to AI-related patents; compute an “AI exposure” score. (3/5)
A diagram explaining how we extracted ‘tasks’ from each job post. A task is a role or a skillset that is essential for a job position. We query based on extracted tasks and retrieve the most similar AI-related patents in terms of semantic similarities. Weighted AI Index is calculated as the sum of the product between the task weight and the similarity of the task and the retrieved patent. Full LLM prompt for extracting tasks from a job post.

AI doesn't affect all jobs equally. Some industries and roles are far more exposed to disruption from technological innovation than others. (2/5)
A bar chart comparing ‘weighted AI index (wAII)’ of different industry sectors. wAII is our proposed method of measuring how much a job position is exposed to AI technologies.

It’s a question that keeps many of us up at night—and for good reason.
Our new research maps labor market vulnerability in the age of AI with 100K job postings and 50K AI-related patents. (1/5)
