An AI technique that automatically identifies and classifies named objects — people, places, organisations, dates, products — within unstructured text. Like highlighting all the important nouns in a document automatically.
Entity extraction applied to customer support emails automatically pulls out product names, order numbers, and dates, allowing tickets to be routed without anyone reading them manually.
All four provide managed NLP APIs that extract entities from text. AWS and OCI emphasize prebuilt entity detection plus custom models; Azure AI Language offers NER with options like custom NER via Language Studio; GCP’s Natural Language focuses on entity analysis with salience and knowledge graph linking where available.
