New method improves CEFR level assessment in text across languages

Researchers have developed a novel approach for automatically assessing CEFR levels in text, addressing challenges like imbalanced data and ambiguous level boundaries. Their method combines focal loss to handle underrepresented examples with supervised contrastive learning for better representation discrimination. This unified objective has demonstrated superior performance over existing baselines in both monolingual and multilingual settings, setting new state-of-the-art results on CEFR assessment benchmarks.
