Record Linkage

Record linkage focuses on determining whether records across different datasets refer to the same entity. It is closely related to entity resolution, but becomes especially prominent in multi-source integration settings. This problem is widespread in healthcare, public-sector, finance, and customer analytics environments. Without strong linkage processes, fragmented data never becomes unified, and enterprise reality remains split across systems. For that reason, record linkage is not just a technical matching task, but a core data integrity problem.
