We created a corpus to identify salient features of Rioplatense Spanish within a specific community: young university students over eighteen years of age. Given the recent advances in generative artificial intelligence, it is essential that research in NLP provide this “intelligence” with access to the language varieties of all Spanish-speaking communities, so that it does not become an unreal, globalized product. Our aim has been to use the corpus in its raw form, without corrections or modifications, and to expand the dictionaries and grammars available in our Spanish Module Argentina [10] on the NooJ platform developed by Max Silberztein [9]. This has allowed us to examine the linguistic diversity of UNR students and to determine the type of language they use. A clear understanding of this linguistic landscape will enable us to enrich the Spanish Module Argentina with distinctive expressions, initially tagged as [+GRJOV], or “gramática de jóvenes,” youth grammar. Moreover, this knowledge will inform the development of teaching materials or even guide the creation of new discourse labels. The corpus will be made publicly available through the UNR data repository [8], facilitating future research and applications.
