QUESTION ANSWERING DEVICE, QUESTION ANSWERING METHOD, AND QUESTION ANSWERING PROGRAM

摘要

A question-answering device, a question-answering method, and a question-answering program that can obtain an answer to an inputted query with high probability are described. A score calculation element 305 determines a matching degree between the group of the style and the topic of an inputted query and the group of the style and the topic of the query of question-answer pairs. A search result presentation element 306 narrows the question-answer pairs on the basis of the matching degree.
