# Entity Resolution
**Entity class:** Analytic method
**Maturity:** Developed
## Definition
**Entity resolution** determines whether records from different systems refer to the same person, organization, account, device, vehicle, place, or event. It is the identity-hygiene prerequisite for answering “who knows who”: false merges create spurious associations, while missed merges hide real ones.

## Civilian intelligence marketplace — operational bridge
Record matching sits at the enrichment gate between raw observations and an operational subject view. [[wiki/LexID|LexID]], [[wiki/Consolidated Case Profile|Consolidated Case Profile]], [[wiki/Probabilistic Record Linkage|Probabilistic Record Linkage]], and [[wiki/Address-Confidence Scoring|Address-Confidence Scoring]] show different mechanisms and outputs. The supplied ELITE account uses the [[wiki/Fellegi-Sunter Model|Fellegi-Sunter Model]] as a general methodological reference.
