Authors: - Agustín Lucas - Alexis Baladón - Victoria Pardiñas - Marvin Agüero-Torales - Santiago Góngora - Luis Chiruzzo ## Related resources The work presented in this paper was part of an undergraduate thesis, named "Generación de datos sintéticos para traducción automática entre español y guaraní" (*Synthetic Data Generation for Spanish-Guarani Machine Translation*). ### Grammars for Spanish and Guarani One of the main components of this work is the development of a Feature Grammar to model simple Spanish-Guarani sentence pairs. The code for the grammar and the resources needed to run can be found in this repository. ### NMT experiments using MarianNMT (C++) The experiments were carried out using MarianNMT. You can find the code here. ### Jojajovai corpus To fine-tune and test the models we use the Jojajovai parallel corpus, consisting of 8 subsets with different kinds of text (e.g. journalistic, user interfaces). ## Paper Published paper (ACL Anthology): aclanthology.org ## Citation If you use some part of this work in your research, please cite: Agustín Lucas, Alexis Baladón, Victoria Pardiñas, Marvin Agüero-Torales, Santiago Góngora, and Luis Chiruzzo. 2024.
