How Do I Set the Right Confidence Threshold to Ensure the Recognition Accuracy?

The confidence score is calculated based on algorithms and is not directly correlated to the accuracy of the corresponding field. There may be cases where the confidence score is high but the recognition results are still inaccurate, or the confidence score could be low but the recognition results are correct.

Confidence and accuracy are different. You can set a confidence threshold based on service requirements and then select the fields whose confidence score is lower than the threshold, and manually confirm those fields. The confidence threshold is user-defined based on service requirements.
