Unreasonable answer filter

摘要

An approach is provided in which a knowledge manager computes a set of unreasonable answer probabilities based upon a corresponding set of answers. Each of the set of unreasonable answer probabilities indicate a likelihood that its corresponding answer is an unreasonable answer to a question received by the knowledge manager. The knowledge manager determines that one or more unreasonable answers are included in the set of answers based upon determining that their corresponding unreasonable answer probabilities are above a threshold. In turn, the knowledge manager removes the one or more unreasonable answers from the set of answers and provides a modified set of answers to a user.

1. A method implemented by a question answer system that includes a memory and a processor, the method comprising:
training an unreasonable answer filter using a set of training questions, a set of training answers corresponding to the set of training questions, and a set of unreasonable answers corresponding to the set of training questions; computing, by the unreasonable answer filter, one or more unreasonable answer probabilities of one or more ranked answers in a set of ranked answers, wherein each of the one or more unreasonable answer probabilities indicate a likelihood that its corresponding ranked answer is an incorrect answer to a question; determining, by the unreasonable answer filter, that at least one of the one or more unreasonable answer probabilities reaches a threshold, indicating that their one or more corresponding ranked answers are one or more unreasonable answers to the question; removing the one or more unreasonable answers from the set of ranked answers, resulting in a modified set of ranked answers; and providing the modified set of ranked answers to a user.
