EL4NER: Ensemble Learning for Named Entity Recognition via Multiple Small-Parameter Large Language Models
EL4NER ensembles three small open-source LLMs with task decomposition, span-aware retrieval, and self-verification, reporting competitive or better NER F1 than GPT-4o-based baselines on two of three datasets.
