Construction of Wakamono Kotoba Emotion Dictionary and Its Application

Currently, we can find a lot of weblogs written by young people. In the weblogs, they tend to describe their undiluted emotions or opinions. To analyze the emotions of young people and what causes those emotions, our study focuses on the specific Japanese language used among young people, which is called

Wakamono Kotoba

. The proposed method classifies

Wakamono Kotoba

into emotion categories based on superficial information and the descriptive texts of the words. Specifically, the method uses literal information used for

Wakamono Kotoba

, such as Katakana, Hiragana, and Kanji, etc., stroke count, and the difficulty level of the Kanji as features. Then we classified

Wakamono Kotoba

into emotion categories according to the superficial similarity between the word and the

Wakamono Kotoba

registered in the dictionary with an annotation of its emotional strength level. We also proposed another method to classify

Wakamono Kotoba

into emotion categories by using the co-occurrence relation between the words included in the descriptive text of the

Wakamono Kotoba

and the emotion words included in the existing emotion word dictionary. We constructed the

Wakamono Kotoba

emotion dictionary based on these two methods. Finally, the applications of the

Wakamono Kotoba

emotion dictionary are discussed.
