Domain Adaptation in Projection-Based NER for Low-Resource Cross-Lingual Transfer

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: What is the impact of domain adaptation on the cross-lingual transfer performance of projection-based NER when evaluated on out-of-domain benchmarks (e.g., scientific, legal, or social media domains) for low-resource languages?
