Named Entity Recognition

NER QA ensures entities in text are accurately detected, classified, and standardized. It improves precision, recall, and schema compliance for reliable training data and model performance.

Make Your Entity Tagging Accurate, Consistent, and Model-Ready

At Prudent Partners, we specialize in the quality assurance of Named Entity Recognition (NER) outputs generated by large language models (LLMs), fine-tuned NLP systems, and custom domain models. Our NER QA services ensure your AI accurately detects, classifies, and labels entities like people, locations, organizations, dates, products, and more.

In critical applications—from compliance automation to customer support to medical record analysis—incorrect entity recognition can lead to misinformation, regulatory risk, or broken product experiences. We provide human-in-the-loop NER validation to safeguard quality at scale.

What is NER QA?

Named Entity Recognition (NER) is the task of locating and classifying named entities in unstructured text into predefined categories. QA for NER focuses on verifying that:

Entities are correctly extracted (boundary accuracy)
No important entities are missed (recall)
Entity types are properly labeled (classification accuracy)
Unnecessary or invalid spans are not labeled (precision)

Quality Control: Our 3-Layer QA Process

We follow a rigorous 3-layer quality assurance process to ensure every annotation meets the highest standards. Each dataset goes through annotator self-review, peer validation, and a final audit by a team lead—resulting in 98–99% accuracy and consistently reliable training data.

Workflow

Kickoff to Delivery

We follow a streamlined, step-by-step workflow—from NDA signing to final delivery—ensuring speed, transparency, and high-quality results at every stage.

Accurate Entity Tagging Starts with Human QA

If your model is classifying entities, make sure someone’s verifying them. Partner with Prudent Partners to build trust, accuracy, and consistency into your NER pipeline.
