Watched hypothesis for deep question answering

摘要: In an approach to watching hypotheses in a deep question answering system, one or more processors receive a question from a user and generate a first result set based on the question. One or more processors receive a request from the user to watch one or more hypothesis answers in the first result set. One or more processors generate a second result set based on the question, where the second result set is generated at a later time than the first result set. One or more processors further determine a similarity score between a hypothesis answer in the second set of one or more hypothesis answers and the watched one or more hypothesis answers and, responsive to determining that the similarity score is below a predetermined threshold, one or more processors send a contradiction alert to the user indicating a potential alternative hypothesis.
