6. The system of claim 1 , wherein the processor is further configured to execute the computer-executable instructions to identify the first group of the plurality of records by at least: accessing a first record, a second record, and a third record of the plurality of records; accessing a blocking model including information indicative of at least a first field and a second field to be compared between candidate pairs of records; comparing a value of the first field of the first record with a value of the first field of the second record to determine first matching fields; comparing a value of the second field of the first record with a value of the second field of the second record to determine second matching fields; in response to determining the first matching fields and the second matching fields, grouping the first record and the second record into the first group; comparing the value of the first field of the second record with a value of the first field of the third record to determine third matching fields; comparing the value of the second field of the second record with a value of the second field of the third record to determine fourth matching fields; and in response to determining the third matching fields and the fourth matching fields, adding the third record to the first group.
8. The system of claim 6 , wherein determining at least one of the first, second, third, or fourth matching fields is based at least in part on a weighting.
