Abstract：Lexical knowledge acquisition is the bottleneck for many tasks like word sense disambiguation, lexical knowledge base construction et al. This paper introduces an automatic word sense discrimination method for Chinese mid-high-frequency adjectives. We employ the EM algorithm and exploit the features of Chinese character, contextual bag-of-words and host-attribute pair instead of the more unreliable syntactic information. We further optimize the morphology selection by utilizing HowNet in our work. The experimental results show that word sense discrimination results are different from Chinese lexicons and could be used for lexicon modification and expansion even for other type of Chinese words.
