Scaling Out-of-Domain Unlabeled Data for Robust Cross-Lingual NER Alignment in Low-Resource Settings

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 increasing the volume of out-of-domain unlabeled target data improve the robustness of cross-lingual NER alignment in low-resource settings?
