Contextual Valence Shifters Supporting Affect Analysis of Utterances in Japanese
نویسندگان
چکیده
The paper presents a support method for affect analysis of utterances in Japanese. One of the problems in the system for affect analysis developed by us before was confusing the valence of emotion types in the final stage of analysis. The cause of this problem was extracting from the utterance only the emotive expression keyword without its grammatical context. To solve this problem we enhance the emotion types extraction procedure in the baseline system with grammatical analysis using Contextual Valence Shifters (CVS). CVS are words, or phrases such as "not", "very much" "not quite", which determine the semantic orientation of the valence of emotive expressions.
