Indo-European phylogenetics with R

Phylogenetics of Indo-European Language families via an Algebro-Geometric Analysis of their Syntactic Structures

Using Phylogenetic Algebraic Geometry, we analyze computationally the phylogenetic tree of subfamilies of the Indo-European language family, using data of syntactic structures. The two main sources of syntactic data are the SSWL database and Longobardi’s recent data of syntactic parameters. We compute phylogenetic invariants and likelihood functions for two sets of Germanic languages, a set of ...

Proto-Indo-European Lexicon: The Generative Etymological Dictionary of Indo-European Languages

Proto-Indo-European Lexicon (PIE Lexicon) is the generative etymological dictionary of Indo-European languages. The reconstruction of Proto-Indo-European (PIE) is obtained by applying the comparative method, the output of which equals the Indo-European (IE) data. Due to this the Indo-European sound laws leading from PIE to IE, revised in Pyysalo 2013, can be coded using Finite-State Transducers...

Indo-European Practice and Historical Methodology

One element of the recent controversy over historical methodology set o by Greenberg (1987)'s classi cation of American Indian languages has been his reliance on super cial lexical resemblances, with no attempt to establish phonological correspondences and no evidence from submerged morphology. Proponents of this methodology argue (Greenberg 1949, 1987, 1990, 1991 Ruhlen 1987) that this is the ...

Alignment Across Oriental and Indo-European Languages

The linguistic characteristics of Oriental languages and Indo-European languages are very different. Using purely length-based algorithm could not produce high performance on aligning texts. This paper investigates the effectiveness of critical part-of-speech (POS) criterion on alignment under conditions of different search strategies and different register texts. Two metrics, recall and precis...
