In recent years, researchers have begun to pay more attention to the emotion recognition in natural language processing. In order to help this pursuit, this paper proposes a semi-automatic approach to create a Chinese emotion thesaurus with tag of emotion intensity based on two kinds of language resources HowNet and Tongyici Cilin. As a basic emotion resource, the emotion thesaurus should be used to help the classification and recognition of emotion in Chinese. We present a new algorithm of the semantic similarity computation for aiding the emotion intensity computation between words. The experimental results on verbs prove that our approach is feasible and effective.
