This paper proposes an unsupervised method of acquiring knowledge about the abbreviation possibility of multiplex verb/noun phrases. Our method calculates weight values of verb/noun phrases and the weight values are calculated by mutual information based on degree of combination of verb/noun phrases and modified verbs/nouns. And, our method recognizes verb/noun phrases possible to be abbreviated by comparing weight values of verb/noun phrases. The evaluation of our method by experiments shows that the precision attains 73.4% and the recall attains 45.9% in case of noun phrases and the precision attains 74.7% and the recall attains 42.9% in case of verb phrases.
