Abstract
Emotion estimation from sentences is helpful in semantic analysis and human-computer interaction. People sometimes express their emotions directly and sometimes describe experiences that produce various emotions. Emotion estimation requires both verbal expressions. We believe Japanese onomatopoeias could serve as a landmark of emotions. In this study, multiple raters judged emotions found in 324 onomatopoeias. %We classified 324 onomatopoeias into eight emotional categories based on the evaluation. We quantitatively evaluated the degree of agreement among the raters and attempted to improve it.
