Definition
What this term means
A uniquely identifiable concept, such as a company, product, person, or location, that AI systems recognise as a distinct 'thing' in the world. Entities have attributes (like founding date, industry, or location) and relationships to other entities (like 'manufactures', 'competes with', or 'is headquartered in'). AI models use entity understanding to connect information across sources and form coherent knowledge.
Why it matters
The business impact
If AI systems cannot recognise your brand as a distinct entity, they cannot accurately describe, compare, or recommend it. Strong entity signals, including consistent naming, clear attributes, and well-documented relationships, help AI models build an accurate internal representation of your brand. Weak entity signals lead to confusion, misattribution, and missed recommendations.
Used in context
How you might use this term
“A company with a common name discovered that AI models were conflating them with an unrelated business. By strengthening entity disambiguation through consistent naming, structured data, and authoritative references, they established a clear, distinct entity identity across all major AI platforms.”

Knowledge Graph
A structured database that maps entities and the relationships between them, creating a web of interconnected knowledge. Google's Knowledge Graph, Wikidata, and similar systems store billions of facts about people, places, organisations, and concepts, powering the knowledge panels, rich results, and AI-generated answers that appear across search and AI platforms.
Named Entity Recognition
An NLP technique that enables AI systems to automatically identify, extract, and categorise named entities, such as people, organisations, locations, products, and dates, from unstructured text. NER is a foundational capability that allows AI models to understand who and what is being discussed in any piece of content, and to connect those entities to their knowledge base.
Schema Markup
A standardised vocabulary maintained by Schema.org, a collaboration between Google, Microsoft, Yahoo, and Yandex, that provides a common language for structured data on the web. Schema markup defines hundreds of entity types (Organisation, Product, Article, Person, Event, etc.) and their properties, enabling web publishers to describe their content in a way that any search engine or AI system can understand.
