"Beating 250,000 Mental Comparisons: A Cross-Domain Engineer's Entity Resolution Case Study"

A cross-domain engineer built an entity resolution tool using AI collaboration, catching 99.2% of human-detected errors in 8 weeks of historical data. This tool turned a weekly task into something anyone can run, and its design retrofitted well to psychological theories. Entity resolution is a universal problem in mid-to-large businesses, requiring periodic reconciliation of business entities across multiple systems. This task is cognitively demanding, with up to 250,000 mental comparisons, making it difficult for humans to perform. The engineer's tool provides a solution to this problem.
