Robustness of Cross-Lingual NER in Low-Resource Languages with Typological Divergence

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: To what extent does the teacher-student learning framework for cross-lingual NER maintain robustness when evaluated on low-resource languages with significant typological divergence from source languages?
