Imperialismo Computacional en Lingüística.

La reconstrucción de proto-lenguas, hipotéticas lenguas ancestrales de las que se derivarían las lenguas actuales, ha sido una actividad que han desarrollado de manera casi artesanal por los practicantes de la lingüistica comparativa o histórica, y no siempre de manera pacífica (ya hemos comentado que las batallas intelectuales más encarnizadas que hemos presenciado en los foros o comentarios de blogs en Internet han sido entre lingüistas…).

Por eso no sabemos si los miembros de esta comunidad científica habrán dado la bienvenida o todo lo contrario a este nuevo resultado científico que les va a ahorrar (posiblemente, a medio plazo se lo quitará) mucho trabajo.

Título. Automated reconstruction of ancient languages using probabilistic models of sound change

Abstract. 

One of the oldest problems in linguistics is reconstructing the words that appeared in the protolanguages from which modern languages evolved. Identifying the forms of these ancient languages makes it possible to evaluate proposals about the nature of language change and to draw inferences about human history. Protolanguages are typically reconstructed using a painstaking manual process known as the comparative method.

We present a family of probabilistic models of sound change as well as algorithms for performing inference in these models. The resulting system automatically and accurately reconstructs protolanguages from modern languages. We apply this system to 637 Austronesian languages, providing an accurate, large-scale automatic reconstruction of a set of protolanguages. Over 85% of the system’s reconstructions are within one character of the manual reconstruction provided by a linguist specializing in Austronesian languages. Being able to automatically reconstruct large numbers of languages provides a useful way to quantitatively explore hypotheses about the factors determining which sounds in a language are likely to change over time. We demonstrate this by showing that the reconstructed Austronesian protolanguages provide compelling support for a hypothesis about the relationship between the function of a sound and its probability of changing that was first proposed in 1955.
