A Factorial Study of Synthetic Data Generation for Low-Resource Machine Translation using Grammar Books

Varun Ghat Ravikumar, Sina Ahmadi, Lena Jäger +1

Most endangered languages lack the parallel data required for machine translation, despite the existence of descriptive grammar books. We introduce a pipeline that uses large langu…

Parity-Aware Byte-Pair Encoding: Improving Cross-lingual Fairness in Tokenization

Negar Foroutan, Clara Meister, Debjit Paul +4

Tokenization is the first -- and often least scrutinized -- step of most NLP pipelines. Standard algorithms for learning tokenizers rely on frequency-based objectives, which favor…

Translation Asymmetry in LLMs as a Data Augmentation Factor: A Case Study for 6 Romansh Language Varieties

Jannis Vamvas, Ignacio Pérez Prat, Angela Heldstab +3

Recent strategies for low-resource machine translation rely on LLMs to generate synthetic data from higher-resource languages. We find that this method fails for Romansh, because L…

Dia-Lingle: A Gamified Interface for Dialectal Data Collection

Jiugeng Sun, Rita Sevastjanova, Sina Ahmadi +2

Dialects suffer from the scarcity of computational textual resources as they exist predominantly in spoken rather than written form and exhibit remarkable geographical diversity. C…
