A quantitative study on the genetic relationship of Miao-Yao languages: the lexicostatics approach
- 人文学院－已发表论文 
运用词源统计分析法对苗瑶语族语言作数理分类,比较传统的分类和其他计量方法的分类结果,认为Swadesh的100词可以用作苗瑶语分类的标准,并描述出苗瑶语族语言之间亲缘距离的程度,同时也说明一种语言中的不同的词汇范畴具有不同的变化程度,即使是基本词汇的变化程度也不能假定为一种相同的值的理论。This study applies the lexicostastics method to quantitatively classify a group of Miao -Yao languages. The resultant classification is compared with those obtained from traditional methods and other computational methods. It confirms that the first 100 basic words proposed by Swadesh provide a valid basis for classifying Miao-Yao languages. The lexical distances between languages are described in the classification derived from the lexicostatistics analysis. It has been observed that words in different lexical categories have different replacement rates. Even words in the basic vocabulary can not always be assumed to have an identical replacement rate.
