Title: METHOD AND DEVICE FOR QUESTION RESPONSE
Abstract:
Disclosed in an embodiment of the present invention is a method for question response, comprising: acquiring target question information; according to the target question information, determining a candidate question-response pair; calculating a degree of confidence in response information in the candidate question-response pair; the degree of confidence is used for indicating the probability that question information in the candidate question-response pair is related to a response database or an opposing database, the degree of confidence being positively correlated to the probability that the question information in the candidate question-response pair is related to the response database; determining whether the degree of confidence is lower than a first preset threshold value; when the degree of confidence is lower than the first preset threshold value, then outputting "unable to respond". Thus, after determining the candidate question-response pair from within a knowledge base according to a degree of matching, a degree of confidence is calculated for all response information; if the degree of confidence is high, the response information may be outputted, and if the degree of confidence is low, "unable to respond" is outputted so as to avoid misleading users and to increase the accuracy of a response.
