Claim 0:
1. A method, comprising:
receiving, by a question answering system having a confidence threshold, plural questions from one or more user devices; and
processing, by the question answering system, each respective one of the plural questions by:
generating an answer to the respective one of the plural questions;
determining a confidence score of the answer;
in response to determining the confidence score is greater than the confidence threshold, increasing the confidence threshold and returning the answer to a respective one of the one or more user devices that generated the respective one of the plural questions; and
in response to determining the confidence score is less than the confidence threshold, decreasing the confidence threshold and not returning the answer to the respective one of the one or more user devices that generated the respective one of the plural questions,

wherein the increasing the confidence threshold and the decreasing the confidence threshold are performed such that the question answering system returns answers for the plural questions at a rate that approximates a pre-defined target answering frequency.
