Abstract
There are numerous onomatopoeic words unique to the Japanese language. Those words are indispensable to make smoother communication in Japanese. Though native speakers of Japanese normally use onomatopoeias without thinking, they can hardly restate them in different terms, let alone explain what they mean. It is said that onomatopoeias are quite hard to master for people studying Japanese. One way to do this is the exposure to many sentences that contain onomatopoeia, and hence we propose an automatic onomatopoeia sentences extraction method based on an analysis of example sentences. As a result, our method extracts 15,437 onomatopoeia sentences from 41,315 blog entries and achieves an accuracy of 96.2% (481/500).
