Constructing a Chinese valence-arousal dictionary with multiple heterogeneous lexicons

This paper proposed an approach to estimate the DSAW-defined valence of words. The valence is converted from sentimental polarity and strength of each word in the CSWN, according to the training data provided by DSAW. In addition, this paper also proposed a method to estimate the arousal for each word based on an observation: increasingly more positive and negative sentiments suggest a stronger arousal. Experimental results show that there is no considerable difference in the prediction results between the methods proposed by this study and other methods. To build a sentiment lexicon under the lack of language tools or resources, the methods proposed in this study may be some of the options for solving the problems.
