Yet another relevant variable is geography, since the spatial propinquity of languages influences the similarity of their overall typological profile; moreover, specific historical events affecting language distributions, such as migrations or the development of certain cultural advantages, are usually also anchored geographically. In this paper we replicate previous findings on a substantially larger set of data drawn from comparative wordlists in the database of the Automated Similarity Judgment Program (ASJP), and discuss the relationships among the three variables mentioned in the title of the paper as well the influence of geography, including the idea that phonemic diversity across the world's languages provides evidence for an out-of-Africa model of the expansion of languages. }, journal = {Linguistic Typology}, author = {Wichmann, Søren and Rama, Taraka and Holman, Eric}, year = {2011}, volume = {15}, number = {2}, pages = {177--197}, } @inProceedings{rama-borin-2011-estimating-140688, title = {Estimating Language Relationships from a Parallel Corpus. A Study of the Europarl Corpus}, abstract = {Since the 1950s, linguists have been using short lists (40–200 items) of basic vocabulary as the central component in a methodology which is claimed to make it possible to automatically calculate genetic relationships among languages. In the last few years these methods have experienced something of a revival, in that more languages are involved, different distance measures are systematically compared and evaluated, and methods from computational biology are used for calculating language family trees. In this paper, we explore how this methodology can be extended in another direction, by using larger word lists automatically extracted from a parallel corpus using word alignment software. We present preliminary results from using the Europarl parallel corpus in this way for estimating the distances between some languages in the Indo-European language family.}, booktitle = {NEALT Proceedings Series (NODALIDA 2011 Conference Proceedings)}, author = {Rama, Taraka and Borin, Lars}, year = {2011}, volume = {11}, pages = {161--167}, } @article{wichmann-etal-2011-correlates-158467, title = {Correlates of reticulation in linguistic phylogenies}, journal = {Language Dynamics and Change.}, author = {Wichmann, Søren and Holman, Eric and Rama, Taraka and Walker, Robert S.}, year = {2011}, volume = {1}, number = {2}, pages = {205--240}, }
