摘要:

我们通过考虑Longobardi(2017 b),Collins(2010),Ceolin et al.(2020)和Koopman(2011)的句法结构数据来研究句法信息中存在的系统发育信号。首先集中在一般的马尔可夫模型,我们探讨如何以及句法结构的数据符合这些模型所要求的假设。我们这样做是通过比较派生的系统发育树对树同意由语言学界。然后,我们将Ceolin et al.(2020)的方法解释为无限站点进化模型,并将数据的一致性与这种替代方法进行比较。本文讨论的思想和方法比句法结构的具体设置更普遍适用,并且可以用于其他情况下,当分析数据与假设的进化模型的一致性时。

英文摘要:

We study phylogenetic signal present in syntactic information by considering the syntactic structures data from Longobardi (2017b), Collins (2010), Ceolin et al. (2020) and Koopman (2011). Focusing first on the general Markov models, we explore how well the the syntactic structures data conform to the hypothesis required by these models. We do this by comparing derived phylogenetic trees against trees agreed on by the linguistics community. We then interpret the methods of Ceolin et al. (2020) as an infinite sites evolutionary model and compare the consistency of the data with this alternative. The ideas and methods discussed in the present paper are more generally applicable than to the specific setting of syntactic structures, and can be used in other contexts, when analyzing consistency of data with against hypothesized evolutionary models.
