N2 - The use of similarities has been one of the main approaches to resolve the ambiguities of coordinate structures. In this paper, we present an alternative method for coordination disambiguation, which does not use similarities. Our hypothesis is that coordinate structures are supported by surrounding dependency relations, and that such dependency relations rather yield similarity between conjuncts, which humans feel. Based on this hypothesis, we built a Japanese fully-lexicalized generative parser that includes coordination disambiguation. Experimental results on web sentences indicated the effectiveness of our approach, and endorsed our hypothesis.
