What is Entity Resolution?

Entity resolution (also known as record linkage, data linkage, object identification, or deduplication) is the task of identifying records in a dataset or across multiple datasets that refer to the same real-world entity. It is commonly used to improve data quality, consolidate customer information, detect fraud, and build a unified view of entities across disparate systems. It typically involves comparing records based on multiple attributes (e.g., name, address, phone number) and applying matching algorithms to determine if they represent the same entity.
