Synthetic Data and Annotation Projection for Low-Resource NER Performance

Cross-lingual Named Entity Recognition (NER) leverages knowledge transfer between languages to identify and classify named entities, making it particularly useful for low-resource languages. We show that the data-based cross-lingual transfer method is an effective technique for crosslingual NER and can outperform multilingual language models for low-resource languages. This paper introduces two key enhancements to the annotation projection step in cross-lingual NER for low-resource languages. First, we explore refining word alignments using back-translation to improve accuracy. Second, we pres

Research goal: Does combining synthetic data with annotation projection yield higher F1 scores for named entity recognition in low-resource languages than using multilingual pre-trained models alone?
