14. The system of claim 10 , wherein the at least one processor is further configured to execute the computer-executable instructions to cause the system to perform the method further comprising: determining, from the merged table, and based at least in part from the aggregate weights, a first leading scorer of the matched fields and a second leading scorer of the matched fields, the first leading scorer associated with a record having a highest aggregate weight and the second leading scorer associated with a record having a second highest aggregate weight; determining a first condition comprising whether a first weight associated with the first leading scorer meets or exceeds a first predetermined value; determining a second condition comprising whether a difference between the first weight and a second weight associated with the second leading scorer meets or exceeds a second predetermined value; and wherein the matching entity corresponds to the first leading scorer and is based at least in part on the determining of the first condition and on the determining of the second condition.

The system of claim 10 , wherein the at least one processor is further configured to execute the computer-executable instructions to cause the system to perform the method further comprising: determining, from the merged table, and based at least in part from the aggregate weights, a first leading scorer of the matched fields and a second leading scorer of the matched fields, the first leading scorer associated with a record having a highest aggregate weight and the second leading scorer associated with a record having a second highest aggregate weight; determining a first condition comprising whether a first weight associated with the first leading scorer meets or exceeds a first predetermined value; determining a second condition comprising whether a difference between the first weight and a second weight associated with the second leading scorer meets or exceeds a second predetermined value; and wherein the matching entity corresponds to the first leading scorer and is based at least in part on the determining of the first condition and on the determining of the second condition. 16. The system of claim 14 , wherein the at least one processor is further configured to execute the computer-executable instructions to cause the system to perform the method further comprising: merging aggregate weights of one or more entities associated with intermediate hierarchy levels in the grouping in response to determining that the first condition or the second condition is not met; re-determining the first condition and the second condition; and outputting a record identifier corresponding to an entity associated with a lowest hierarchy level of the grouping in response to re-determining the first condition and the second condition.
