Summary: 
This paper proposes a statistical method of acquiring knowledge about the abbreviation possibility of some of multiple adnominal phrases. Our method calculates weight values of multiple adnominal phrases by mutual information based on the strength of relation between the adnominal phrases and modified nouns. Among adnominal phrases, those having relatively low weight values are deleted. The evaluation of our method by experiments shows that precision attains about 84.1% and recall attains about 59.2%, respectively.
