Abstract:
1. A computer-implemented method to halt execution of queries containing entity resolution (ER) candidate-building keys unsuitable for generating a restricted set of candidate entities against which to match a received identity record, the method comprising: receiving an identity record; determining a plurality of ER candidate-building keys for the received identity record; generating a query from one or more of the plurality of ER candidate-building keys to retrieve entities matching any of the one or more ER candidate-building keys, wherein the one or more ER candidate-building keys are derived from at least a field of the received identity record; upon determining, during execution of the query and by operation of one or more computer processors, that at least a first ER candidate-building key of the one or more ER candidate-building keys is unsuitable for generating a restricted set of candidate entities against which to match the received identity record, aborting executing the query, wherein the restricted set of candidate entities is selected from a plurality of available entities greater in number than the restricted set of candidate entities; and upon determining that each of the one or more ER candidate-building keys are suitable for generating the restricted set of candidate entities against which to match the received identity record, allowing the query to complete execution, to obtain the restricted set of candidate entities for the received identity record.
