Description

UD_Kadiweu-UNICAMP is a treebank for Kadiwéu (ISO-639: kbc), an endangered Indigenous language of Brazil. It consists of isolated sentences produced by native speakers.

Kadiwéu is a polysynthetic language spoken in the state of Mato Grosso do Sul, Brazil. It is severely endangered: among approximately 1,500 Kadiwéu people, fewer than 300 speak the language, as many have shifted to Portuguese (Pires 2022). Kadiwéu is the only representative of the Waikurúan linguistic family in Brazil. This family includes four additional languages: Toba, Pilagá, and Mocoví, mostly spoken in Argentina, and Abipón, formerly spoken in Argentina but now extinct (Sandalo 1995).

UD_Kadiweu-UNICAMP is the first treebank for a Waikurúan language in the UD collection, contributing to the documentation and computational modeling of a poorly documented and under-resourced language family. It is an ongoing project, currently consisting of isolated sentences produced by native speakers, most of which are translations of Portuguese sentences. Future versions will also include narratives and other genres.

Acknowledgments

The construction of this treebank has been funded by the São Paulo Research Foundation (FAPESP) through the DACILAT project (grant No. 22/09158-5). It is part of the postdoctoral research of Leonel Figueiredo de Alencar at the Department of Linguistics of the State University of Campinas (UNICAMP), under the supervision of Filomena Spatti Sandalo, coordinator of the DACILAT project, and in collaboration with Charlotte Chambelland Galves.

We are much indebted to the speakers of Kadiwéu for sharing their knowledge of their language and for providing translations and acceptability judgements on constructed sentences.
