Question answering system using topic-sensitive source reliability scoring

Abstract:

Embodiments of the present invention are directed to a computer-implemented method for determining topic specific reliability for a question answering system. A non-limiting example of the computer-implemented method includes receiving a topic specific input query by the question answering system. The method further includes detecting a source that provides a reference containing the ground truth answers to the ground truth questions. The method further includes traversing sources detect similar references in other sources and assigning reliability scores for each source based upon ground truth answers in the other sources. The method further includes providing a ranked list of answers based upon the reliability of each source upon for each answer.
