DIALOGUE SUPPORT SYSTEM AND DIALOGUE SUPPORT METHOD

A dialogue support system holds question/answer pair candidates including a question sentence vector, an emotion vector indicating a question emotion, and an answer sentence vector, outputs a question/answer pair based on question/answer pair candidates included in a first group as a sentence dependence question/answer pair in a case where it is determined that a variance of emotion vectors included in a first group based on similarity between answer sentence vectors and similarity between the question sentence vectors is large, and outputs a question/answer pair based on question/answer pair candidates included in a second group as an emotion dependence question/answer pair in a case where it is determined that a variance of question sentence vectors included in a second group based on similarity between the answer sentence vectors and similarity between the emotion vectors is large.
