Machine translation boosts text difficulty assessment for low-resource languages

Researchers have developed a cross-lingual data augmentation strategy to address the scarcity of expert-annotated corpora for text difficulty assessment, particularly in low-resource languages. By using machine translation to transfer labeled data from high-resource languages, they trained BERT-based regression models. Experiments showed that supplementing limited native data with machine-translated corpora significantly improved the accuracy of difficulty estimation, offering a practical solution for languages lacking extensive annotations.
