Claim 8:
9. A computer program product comprising one or more computer readable storage media having program instructions collectively stored on the one or more computer readable storage media, the program instructions executable to:
receive, by a question answering system, a question from a user device;
generate, by the question answering system, an answer to the question;
determine, by the question answering system, a confidence score of the answer;
compare, by the question answering system, the confidence score to a confidence threshold; and
adjust the confidence threshold, by the question answering system and based on the comparing, by performing one of:
in response to the confidence score being greater than the confidence threshold, increasing the confidence threshold for a next question; and
in response to the confidence score being less than the confidence threshold, decreasing the confidence threshold for the next question;

wherein the increasing the confidence threshold and the decreasing the confidence threshold are performed using at least one algorithm that is a function of a target answering frequency and a learning rate.
