A mechanism is provided in a data processing system for comparing similarity of questioning answer system ground truth answers to question answering system result answers. The mechanism receives question answering system results. The question answering system results comprise questions posed to the question answering system, answers returned by the question answering system for each question posed to the question answering system, and a confidence value for each answer. The question answering system is trained or tested using the ground truth questions and answers. The mechanism performs a matching operation comparing each result answer in the question answering system results to a corresponding ground truth answer. The matching operation is an asymmetric containment comparison and wherein the matching operation determines similarity of each result answer to the corresponding ground truth answer. The mechanism determines whether each result answer is right or wrong based on results of the matching operation.
