Technical Definition
Google's Knowledge Graph is a knowledge base of entities and their relationships. Powers knowledge panels, entity understanding, and helps interpret search queries. Contains billions of facts about people, places, organizations, and things. Entity presence in the Knowledge Graph indicates Google recognizes you as a distinct entity. Informed by Wikipedia, official sources, and structured data.
Simple Explanation (ELI13)
The Knowledge Graph is Google's database of facts about people, places, and things. It's how Google knows that 'Apple' the company is different from 'apple' the fruit. When you see a knowledge panel on the right side of search results, that information comes from the Knowledge Graph.
