18 Claims

1. A question-answer processing method, comprising:

acquiring an input question and a candidate question-answer pair, wherein the candidate question-answer pair comprises a candidate question and a candidate answer matching the candidate question;

inputting the input question into a first model to obtain an input question vector;

calculating a similarity between the input question vector and a candidate question vector, and calculating a relevance between the input question vector and a candidate answer vector, wherein the candidate question vector is a vector corresponding to the candidate question, and the candidate answer vector is a vector corresponding to the candidate answer; and

determining a matching degree of the candidate answer and the input question according to the similarity and the relevance;

wherein the calculating the relevance between the input question vector and the candidate answer vector comprises:

calculating the relevance between the input question vector and the candidate answer vector by a formula 2, wherein the formula 2 is:

rel(vq, va) is the relevance, vq is the input question vector, va is the candidate answer vector, vq^T·va is the transpose of the input question vector and the dot product of the candidate question vector, |vq| is the length of the input question vector, |va| is the length of the candidate answer vector.
