# Grammar-based Data Augmentation for Low-Resource Languages - NAACL2024
This repository contains information about the code and resources used in the *Grammar-based Data Augmentation for Low-Resource Languages: The Case of Guarani-Spanish Neural Machine Translation* paper, accepted at NAACL2024.
✨**TL;DR**✨ In this work we explore the feasability of using grammar-generated text as a Data Augmentation strategy for low-resource languages, and we find that synthetic text is useful to boost Guarani-Spanish Machine Translation systems.

### 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).
