While language contact has so far been predominantly studied on the basis of detailed case studies, the emergence of methods for phylogenetic reconstruction and automated word comparison – as a result of the recent quantitative turn in historical linguistics – has also resulted in new proposals to study language contact situations by means of aut…[Read more]

The fact that “all languages evolve, as long as they exist” (Schleicher 1863: 18f) has been long known to linguists and does not surprise us anymore. The reasons why all language change constantly, however, is still not fully understood. What we know, however, is that language usage must be at the core of language evolution. It is the dynamics amo…[Read more]

Skepticism regarding the tree model has a long tradition in historical linguistics. Although scholars have emphasized that the tree model and its long-standing counterpart, the wave theory, are not necessarily incompatible, the opinion that family trees are unrealistic and should be completely abandoned in the field of historical linguistics has…[Read more]

This presentation covers some basic elements of data collection methods, fieldwork and interacting with speakers of a critically endangered language.

The article reflects on the relationship between the internationalization of higher education and language policies in Brazil. The study provides a review of language policy literature and internationalization policies materialized in national programs, such as the Science without Borders (SwB) and the Languages without Borders (LwB). The analysis…[Read more]

Despite a period of almost two decades in which quantitative approaches in historical linguistics have been increasingly used, gaining constantly more popularity even among predominantly qualitatively oriented linguists, we find many problems in the field of computational historical linguistics, which have only sporadically been addressed. In the…[Read more]

By comparing the languages of the world, we gain invaluable insights into human prehistory, predating the appearance of written records by thousands of years. The traditional methods for language comparison are based on manual data inspection. With more and more data available, they reach their practical limits. Computer applications, however,…[Read more]

While the evolution of spoken languages is well understood and has been studied using traditional historical comparative methods as well as newer computational phylogenetic methods, evolutionary processes resulting in the diversity of contemporary sign languages are poorly understood, and scholars have been largely unsuccessful in grouping sign…[Read more]

The Sino-Tibetan language family is one of the world’s largest
and most prominent families, spoken by nearly 1.4 billion people.
Despite the importance of the Sino-Tibetan languages, their pre-history remains controversial, with ongoing debate about when
and where they originated. To shed light on this debate we
develop a database of c…[Read more]

We present a fully automated workflow for phylogenetic reconstruction on large datasets, consisting of two novel methods, one for fast detection of cognates and one for fast Bayesian phylogenetic inference. Our results show that the methods take less than a few minutes to process language families that have so far required large amounts of time…[Read more]
