Randomized trial demonstrates improved NER performance in multiple data sets, suggesting a novel LLM integration method.

The aim is to improve small named entity recognition models using context rewriting by large language models.
Utilized large language models to modify entity contexts in text.
Evaluated method effectiveness on multiple standard NER data sets.
No retraining or architectural changes were made to the existing NER models.
The method consistently improved NER model performance across all data sets tested, achieving state-of-the-art results.
Effectively addressed challenges of out-of-vocabulary entities and syntactically complex sentences.
Maintained low computational costs during implementation.
