侗台语亲疏关系的计算分析

Computational Analysis on the Relationship among Branches of Kam-Tai Languages

以权威词表的同源语素作为分类特征,对其进行二元量化及科学计算后,构建了侗台语的邻接树和系统发生图,并借助聚类分析及层级分析确定了侗台语的亲疏关系。结论认为:侗台语主体上分为台语和侗水语两个部分,台语内部又分为北部、西南两个小支, 标话、拉珈语、临高语混同黎语集聚成群,它们的地位归属还需要其他证据的支持。

This study adopts the lexical cognates as classification traits and transforms them into binary codes.On this basis,the study establishes a neighbor-joining tree and phylogram,and investigates the relationships among these languages.It is found that the Kam-Tai languages consist of two major branches:Tai languages and Kam-Sui languages.In particular,there are two sub-branches in the Tai languages,namely northern branch and southwestern branch.In addition,the Biao,Lakkja,Be and Hlai languages can be grouped together.And the explanations for this observation need more other evidence.
