Matching validation

A system comprising:

• persistent storage comprising a data repository comprising a plurality of transaction records and a plurality of candidate users transaction records;
• a communication interface configured to obtain an identifier of a target entity;
• at least one computer processor executing:
• a matching model executing on the at least one computer processor, the matching model configured to generate a candidate match between a target entity and a candidate application user;
• and
• a validation model executing on the at least one computer processor, the validation model configured to:
• filter the plurality of transaction records of a plurality of application users to obtain a subset of the plurality of transaction records each involving a transaction with the target entity, the plurality of application users excluding the candidate application user,
• determine, for each transaction record in the subset, whether a matching transaction record exists in the plurality of candidate users transaction records of the candidate application user,
• validate the candidate match when at least a threshold amount of transaction records in the subset has the matching transaction record in the plurality of candidate users transaction records, and
• link, in the persistent storage, the target entity to the candidate application user.

A method comprising:

• obtaining, via a communication interface of a computing system, an identifier of a target entity;
• calculating, by at least one computer processor of the computing system, a normalized distance between a target entity and each of a plurality of candidate application users;
• selecting, by the at least one computer processor, a candidate application user from the plurality of candidate application users as a candidate match with the target entity based on the normalized distance satisfying a threshold distance;
• selecting, by the at least one computer processor, a subset of transaction records in a plurality of transaction records of a plurality of application users that comprise an address of the target entity as a counterparty of a transaction, the plurality of application users excluding the candidate application user,
• determining, for each transaction record in the subset and by the at least one computer processor, whether a matching transaction record exists in a plurality of candidate user transaction records of the candidate application user, wherein determining a matching transaction record exists for a transaction record in the subset comprises:
• determining that a candidate user transaction record is equal and opposite to the transaction record in the subset;
• validating, by the at least one computer processor, the candidate match when at least a threshold amount of transaction records in the subset has the matching transaction record in the plurality of candidate users transaction records;
• and
• linking, in persistent storage of the computing system, the target entity to the candidate application user.
