Definition

Entity extraction is the process by which AI systems identify and pull named entities — people, organizations, locations, products, and concepts — from unstructured text. It is a core component of named entity recognition (NER) and is used to build knowledge graphs and populate retrieval indexes. Entity extraction is how AI systems turn your content into structured knowledge. A page that clearly names and contextualizes the entities it discusses — using full proper names, consistent references, and explicit relationships — produces cleaner entity extraction results than a page that uses pronouns, abbreviations, and vague references. Content written with entity extraction in mind is more likely to be correctly attributed and accurately represented in AI knowledge systems.
