A Knowledge Graph is a structured representation of interconnected information, which organizes data as entities, relationships, and attributes. It is typically visualized as a graph where nodes represent entities (such as people, places, or things), and edges represent the relationships or connections between these entities. The attributes provide additional information or properties about the entities.

Knowledge Graphs are used in various applications, including search engines, recommendation systems, natural language processing, and artificial intelligence. They enable these systems to better understand complex relationships within the data and provide more accurate, relevant, and context-aware results or insights.

Some popular examples of Knowledge Graphs include Google’s Knowledge Graph, which is used to enhance search results and provide quick access to relevant information, and Wikidata, a large, open-source knowledge base that aims to store structured data from Wikipedia and other sources.
