A knowledge graph is a structured map of information. It represents entities (like products, people, or concepts) as nodes, and the connections between them as relationships or edges. This format allows machines to understand not just data, but the context behind it.
For example, Google's knowledge graph helps distinguish between Apple the company and apple the fruit by recognizing context and relationships.
