Job Ad Analysis Toolkit (JAAT) Evidence Dashboard
Job postings and new open-source language models let us test old maps of work and build new maps. This dashboard summarizes public aggregate evidence from the NLx corpus and USAJOBS job postings. The main findings are A. A New Map of Work, B. Analyzing the Mismatch, C. Finding Emerging Skills, and D. Dynamic Maps, with corpus-specific drilldowns under NLx corpus and USAJOBS.
Main findings make curated claims with evidence and cautions; profiler pages are exploratory lookup tools for readers who want to inspect occupations, industries, agencies, tasks, skills, or concepts.
