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 build solutions for multilingual and low-resource environments.
"Verba" (words) + "Nex" (connection) + "AI" — connecting language and intelligence.
