本文采用词向量计算的方式考察汉语名词和动词之间的关系,考察的内容包括典型名词和典型动词的距离关系、动名兼类词以及双音节动词与典型名词、动词的距离关系。结果显示:典型名词与典型动词界限清晰;90%以上的双音节动词仍与典型动词... 详细信息

本文采用词向量计算的方式考察汉语名词和动词之间的关系,考察的内容包括典型名词和典型动词的距离关系、动名兼类词以及双音节动词与典型名词、动词的距离关系。结果显示:典型名词与典型动词界限清晰;90%以上的双音节动词仍与典型动词距离更近。本文还选取了100个例词从整体上观察名词和动词的关系,发现名词和动词虽不像典型名词和动词那样清晰二分,但分出的小支系中名词和动词各不相混。
