使用相似性一直是解决坐标结构歧义的主要方法之一。在本文中，我们提出了一种不使用相似性的协调消歧方法。我们的假设是，坐标结构由周围的依赖关系支持，并且这种依赖关系反而会产生人类感觉的连词之间的相似性。基于这个假设，我们构建了一个日语完全词汇化的生成解析器，其中包括协调消歧。网络句子的实验结果表明了我们方法的有效性，并支持了我们的假设。
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.
