The Merge/Purge Problem for Large Databases

Summary: Defines the merge/purge problem for large multi-source databases, identifying the same individuals across inconsistent records. Compares sorted-neighborhood blocking and clustering; a multi-pass transitive closure over alternate keys improves accuracy at the cost of efficiency. (summarized by gpt-5-nano on Feb 09 2026)
