Named Entity Recognition (NER)

Technical explanation

A natural-language-processing task that identifies and classifies named entities such as people, organisations, locations and dates in text. The technique operates on data and model outputs within a defined use context. Evaluation should cover accuracy, representative performance, human oversight, privacy, security, documentation and monitoring after deployment.

Business relevance

It supports accountable use of AI by making capabilities, evidence and limitations visible to decision-makers.

Implementation example

A cross-functional team applies Named Entity Recognition (NER) in a production initiative, defines ownership and success criteria, tests representative scenarios, monitors outcomes and records corrective actions before scaling.

Limitations and common misconceptions

Model outputs remain probabilistic and context-dependent. Evaluation results can degrade over time and do not by themselves establish fairness, safety or legal compliance.
