Kitchen等人（2009）分析了25种闪族语言的词汇特征数据集，包括古希伯来语、阿拉姆语和阿卡德语，现代南阿拉伯语和阿拉伯语以及15种民族闪族语言。他们使用树和性状模型以及为基因序列数据建立的方法来估计词汇性状多样化的系统发育树。我们在词汇特征数据的无同形模型中重新分析数据。我们使用系统发育的先验，这对于一些关键的科学假设（关于拓扑和根时间）是非信息性的。我们的结果与Kitchen等人（2009）的结果大致一致，尽管我们95%的HPD对闪米特树的根（阿卡德语的分支）是[4400,5100]BP，并且我们将摩洛哥语和欧加登阿拉伯语归入现代南阿拉伯语系。
Kitchen et al. (2009) analyze a data set of lexical trait data for twenty five Semitic languages, including ancient languages Hebrew, Aramaic and Akkadian, modern South Arabian and Arabic languages and fifteen ethiosemitic languages. They estimate a phylogenetic tree for the diversification of lexical traits using tree and trait models and methods set up for genetic sequence data. We reanalyze the data in a homplasy-free model for lexical trait data. We use a prior on phylogenies which is non-informative with respect to some of the key scientific hypotheses (concerning topology and root time). Our results are in broad agreement with those of Kitchen et al. (2009), though our 95% HPD for the root of the Semitic tree (the branching of Akkadian) is [4400, 5100]BP and we place Moroccan and Ogaden Arabic in the Modern South Arabian Group.
