Evaluation for generality of natural Japanese sentence generation method using inductive learning

A lot of unnatural sentences exist in the Japanese sentences which the computer generates in the machine translation, the dialogue processing and so on. The user has dissatisfaction for it. From the point of view of this situation, we previously proposed the method which paraphrases an unnatural Japanese sentence generated by a computer to its natural Japanese sentence with inductive learning. In order to confirm the effectiveness of our proposed method, we constructed the experimental system and carried out the evaluation experiment. The rate of the number of natural sentences in the number of all input sentences improved from 32.4% to 55.3%. From the result of this evaluation experiment, we have confirmed the effectiveness of our method. In this paper, first of all, we explain the outline of our proposal method, and consider the effectiveness of our method through the experimental results.
