Kiyoaki Shirai, Tomotaka Fukuoka · 2018
This paper introduces an annotated corpus of free conversations in Japanese.It is manually annotated with two kinds of linguistic information: dialog act and sympathy.First, each utterance in the free conversation is annotated with its dialog act, which is chosen from a coarse-grained set consisting of nine dialog act labels.Cohen's kappa of the dialog act annotation between two annotators was 0.636.Second, each utterance is judged whether the speaker expresses his/her sympathy or antipathy toward the other participant or the current topic in the conversation.Cohen's kappa of sympathy tagging was 0.27, indicating the difficulty of the sympathy identification task.As a result, the corpus consists of 92,031 utterances in 97 dialogs.Our corpus is the first annotated corpus of Japanese free conversations that is publicly available.
