VerbaNexAI is a research laboratory at the Universidad Tecnológica de Bolívar (UTB), Cartagena, Colombia. We explore the convergence of Natural Language Processing, Artificial Intelligence, and computational linguistics to solve real-world problems in multilingual and low-resource settings.
"Verba" (words) + "Nex" (connection) + "AI" — connecting language and intelligence.
