Entity resolution (also called record linkage, deduplication, or entity matching) is foundational to knowledge graph construction, master data management, and AI retrieval accuracy. Techniques range from rule-based matching (identical tax ID, same name) through probabilistic matching (probabilistic record linkage) to ML-based approaches (embedding similarity, Siamese networks). In AI retrieval contexts, poor entity resolution causes the same entity to be indexed multiple times under different representations — degrading both recall (missing some representations) and precision (returning duplicate results). Entity clarity in structured data (clear, consistent, unique entity identifiers) reduces the burden on entity resolution.
Retailers building product knowledge graphs and enterprises integrating customer data across systems need entity resolution capabilities to create the consistent, deduplicated data that AI retrieval systems require for accurate performance.
Like a post office that must determine that 'J. Smith, 12 Main St' and 'John Smith, No. 12 Main Street' are letters for the same person — combining reference variants to ensure correct delivery.
