Exemplary systems and methods for linking entity references to entities and identifying associations between entities are presented. In particular, a method for delinking one or more entity references linked to a same entity is provided, where the one or more entity references have at least one common data field. The method comprises the steps of evaluating at least one actual measurement of the entity based at least in part on one or more field values of the one or more entity references, determining a difference between the at least one actual measurement and at least one predefined measurement associated with the entity and delinking the one or more entity references based at least in part on a comparison of the difference and a defined threshold.
