Expanded data processing for improved entity matching

A system with improving reliability in entity matching, comprising:

• a processor;
• and
• a memory storage device including instructions that when executed by the processor are operable to:
• receive, from a requestor system, a request for a unique identifier associated with an entity;
• parse the request for requesting demographic fields data related to the entity;
• retrieve records that include indexed demographic data, wherein at least one of the indexed demographic data for each record retrieved matches a corresponding field from the requesting demographic fields data;
• augment the indexed demographic data with expanded demographic data, wherein the expanded demographic data are received from a third party;
• determine a matching confidence for whether the entity is associated with a given record of the records based on the requesting demographic fields data that match the indexed demographic data as augmented by the expanded demographic data;
• in response to the matching confidence satisfying a confidence threshold, select a prior-assigned identifier that is associated with the given record as the unique identifier for the entity;
• in response to the matching confidence not satisfying the confidence threshold, create a new identifier as the unique identifier for the entity;
• and
• transmit the unique identifier to the requestor.

A system with improving reliability in entity matching, comprising:

• a processor;
• and
• a memory storage device including instructions that when executed by the processor are operable to provide a matching system operable to receive identity requests for a given entity and produce an identifier response that includes a unique identifier for the given entity, the matching system including:
• an index, storing indexed demographic data for entities, wherein each entity of the entities is associated with an assigned unique identifier, and wherein the indexed demographic data include one or more indexed demographic data fields with one or more values that are associated with the entities;
• a blocking system, operable to parse the identity request for requesting demographic data fields and return blocks of candidate entities, wherein the candidate entities included in a given block match the requesting demographic data fields according to one or more values of the one or more indexed demographic data fields associated with the candidate entities;
• and
• a matching engine, operable to determine a confidence score for each candidate entity included in the given block to determine whether a matching entity for the given entity is present in the given block, wherein when a matching entity is determined to be present in the given block, the unique identifier included in the identifier response is selected as a prior-existing identifier associated with the matching entity in the index, and wherein when a matching entity is determined to not be present in the given block, the unique identifier included in the identifier response is created as a new identifier which is associated with the given entity in the index.
