An Automatic Funny Proverb Generation System Based on Sukashi

In this paper, we propose a system which produces funny proverbs. This proposed system uses the punch line framework named Sukashi. That is, by changing the end of the line in proverbs defying the prediction of users, the proposed system produces a funny sentence. The proposed system has 3 distinct features: First, the novel framework named Sukashi is employed. Second, various and huge number of Sukashi candidates are generated due to utilizing the Japanese Google N-grams being constructed from 255 billion words. Third, the factors of laughing -imageability and concrete level of the targeted words- are newly added to the sound length, difference of sound and concepts, which are frequently used in pun generation. Due to these factors, funnier Sukashis are able to be selected from candidates using fuzzy rules. We confirmed that the proposed system is able to generate Sukashis quite comparable to human-made ones in terms of both funny level and unpredictable level.
