Scaling Efficiency of Projection-Based Cross-Lingual NER with Parallel Image-Text Data

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: How does the efficiency of projection-based cross-lingual NER scale with the number of parallel sentences in image-text data, as measured by training time and F1 score improvements on XTREME-R low-resource languages?
