Confidence score
A number attached to an automated decision, such as a proposed match or correction, saying how sure the method is that the decision is right.
A score is only useful if it has been checked against known answers. Its usual job is routing: act on the high scores, send the middle to a person, and leave the low ones alone.
Where it comes up
