2. The method of claim 1 , wherein reconfiguring the ranker array based on results of the determined correctness comprises: generating a ranker array reward value for the ranker array based on the correctness of the corresponding ranked listing of candidate answers for each of the rankers in the ranker array; comparing the ranker array reward value to a reward value threshold value; and reconfiguring the ranker array in response to the ranker array reward value not satisfying a predetermined relationship with regard to the reward value threshold value.
5. The method of claim 2 , wherein generating a ranker array reward value comprises generating a ranker reward value for each ranker in the ranker array and generating the ranker array reward value based on a combination of the ranker reward values for each of the rankers in the ranker array.
