FEWTOPNER presents a framework for few-shot, cross-lingual Named Entity Recognition (NER) by integrating topic-aware contextual modeling, combining a multilingual encoder, prototype-based NER, and a cross-task attention mechanism. The model achieves F1 score gains of up to 4.0% over state-of-the-art baselines like MetaNER and improves topic coherence on multilingual datasets.
Key insights
- Integrating topic-aware contextual information directly into the NER process substantially improves entity disambiguation, particularly for ambiguous entities, by providing crucial document-level thematic cues.
- A shared multilingual encoder, combined with language-specific calibration and contrastive learning, effectively facilitates robust cross-lingual transfer and adaptation in data-scarce environments.
- Few-shot learning, powered by prototype networks and a CRF layer, enables accurate and coherent entity recognition even with very limited labeled examples per class.
