Identification of unconfident characters

Fields extracted using an Advanced Zone Locator have confidence values at character level as well as field level. The field confidence is always equal to the lowest of the character confidences.

Within the Details window for the field, you can specify a confidence threshold. Any result that has a confidence lower than the specified confidence threshold is marked as invalid.

If any characters have a confidence below this threshold, their Reject attribute is given a value of 1 and these characters are displayed in Correction.
