 Description  « Hide

The exact matching algorithm can easily be extended to allow for the use of any of the other distance metrics in establishing a match between two records. Being that this is a deterministic algorithm, the boolean decision can be made by comparing the output of any of the distance metrics that return a real number in the range [1,0] against a threshold that must be passed as a parameter to the metric specified for each match field.

The exact matching algorithm can now have an alternate comparison operator other than equality along with a threshold to determine whether the match is exact or not.
