Abstract
Objective: To present the proposal of the Brazilian Linguistic Diversity Platform, an initiative of the Brazilian Association of Linguistics (ABRALIN) and the Sociolinguistics Working Group of the National Association of Postgraduate Studies and Research in Letters and Linguistics (ANPOLL), and to discuss its contribution to the development of Portuguese language models foreseen in the Brazilian Artificial Intelligence Plan (PBIA) 2024-2028.
Methods: Theoretical and propositional essay, based on documentary analysis of the PBIA and on studies of linguistic bias in language models and of the management of sociolinguistic data collections in Brazil.
Results: The language models currently available are trained on data dominated by English, in which Portuguese appears mostly in written, formal, and urban registers, which results in the reproduction of biases, stereotypes, and the invisibility of underrepresented varieties and speakers; meanwhile, linguistic data collections produced by specialists remain fragmented and regionally and institutionally concentrated. The Platform is proposed as a national repository of linguistic data collections, guided by the FAIR principles and supported by a collaborative network of laboratories.
Conclusions: The Platform represents a strategic bridge between linguistic science, data science, information science, and technological development, with impacts on education, language policies, and Brazilian digital sovereignty.
