IQ Bot 11.x: Improve output quality using OCR confidence
Improve the output quality of the IQ Bot platform using the system-identified region (SIR) and optical character recognition (OCR) confidence by comparing it to a predefined threshold.
Confidence-based validation is useful for a text type field and for Date or Number fields because it helps route a document, with contentious values, for a human to view despite the fields satisfying the set validation criteria.
Enable OCR confidence-based validation
This feature is disabled by default. To enable this feature, open the
Settings.txt configuration file available in
<IQ Bot Installation Folder>\Configurations\, and set
the desired threshold value in the ConfidenceThreshold
property. For this example, set the character-level confidence threshold value to
99, that is
this feature is disabled, the default value is set to 0, signifying that the feature
How OCR confidence-based validation works
In a document if a field's SIR character level confidence is lower than that of the set confidence threshold, the validation for that field fails, resulting in the failure of that document.
While training a document, a confidence-based validation failure against a field appears in an orange box during preview if no other validation errors exist for that field. Other validation errors take precedence over OCR character-level confidence validation.
