Deep Dive
A Knowledge Graph is a knowledge base that uses a graph-structured data model to represent entities, their attributes, and the relationships between them in a semantic network. Unlike traditional relational databases that store data in tables, a knowledge graph organizes information as a network of interconnected nodes (entities) and edges (relationships), providing a richer, more contextual, and human-like understanding of information.
