The fully automated method for construction of language taxonomy is tested on a sample of fifty languages of the Indo-European language group and applied to a sample of fifty languages of the Austronesian language group. The Anatolian and Kurgan hypotheses of the Indo-European origin and the ‘express train’ model of the Polynesian origin are thoroughly discussed. http://dx.doi.org/10.1038/npre.2009.3156.3 Mon, 21 Sep 2009 15:20:37 UTC Geometric Representations of Language Taxonomies doi:10.1038/npre.2009.3156.3 2009-09-21 Dimitri Volchenkov Nature Precedings 2009-09-21T15:20:37Z Manuscript Earth & Environment http://creativecommons.org/licenses/by/3.0/
