The state of California now requires counties to find and remove them, but manually combing through millions of documents would take years. Researchers used AI to find them automatically. ...
at Stanford University and Princeton University fine-tuned a large language model to find racial clauses in deeds for property in the California county of Santa Clara.
Key insight: Manual and keyword searches may fail to catch racial clauses if they’re obscured by subtle wording or errors in optical character recognition (OCR). But a fine-tuned large language model can understand context, identify relevant phrases, and avoid potential false alarms like the surnames Black or White. ...
How it works: The authors used an OCR system to extract text from 5.2 million pages of Santa Clara property deeds filed between 1850 and 1980. They drew examples from that corpus to form training and validation datasets and then processed the rest to find deeds that contained racial clauses. ..."
