Knowledge acquisition about the deletion possibility of adnominal verb phrases

We propose a method of acquiring knowledge about the possibility of deletion of adnominal verb phrases from a corpus. Our method acquires such items as the frequency of modification of the noun by adnominal verb phrases and the variety of adnominal verb phrases modifying the noun, from a newspaper corpus, and yields knowledge about the possibility of deletion of adnominal verb phrases by using their statistical information. Our method also identifies adnominal verb phrases modifying nouns with important content as deletable ones. Experimental results show that the precision and the recall attained 77.3% and 69.4%, respectively. © 2006 Wiley Periodicals, Inc.
