Claim 9:
10. A model learning apparatus
a recording medium recording a question/answer pair, which is a pair of a question and an answer, an expansion question/answer pair, and the translation model for obtaining the answer from the question or the reverse translation model for obtaining the question from the answer; and
processing circuitry configured to:
execute a question/answer-pair expansion processing which generates the expansion question/answer pair from the question/answer pair; and
execute a translation-model learning processing which learns at least one of the translation model and the reverse translation model by using the expansion question/answer pair; wherein
the question/answer pair is associated with an index indicating a degree of how much the answer sounds like a character, which is determined in advance, for each of the question/answer pair; and
execute the question/answer-pair expansion processing which generates the expansion question/answer pair by increasing the number of the question/answer pair associated with the index indicating that the answer sounds more like the character, wherein,
the index indicating the degree of how much the answer sounds like the character includes: a first index evaluated by a person other than the character himself/herself, a second index indicating that the answer is responded by the character himself/herself, and a third index indicating that the character himself/herself certified that the respond sounds like the character.
