Abstract
Disclosed herein is a search method including: generating a user question vector for a user question using a paraphrase model learned using first learning data composed of a first pair of questions and a label indicating that the first pair of questions are similar to each other and second learning data composed of a second pair of questions and a label indicating that the second pair of questions are dissimilar to each other; selecting a similar question based on a similarity analysis result to the user question vector; and determining an answer to the similar question as an answer to the user question.
