Knowledge Graphs

A Knowledge Graph (KG) is a structured way of representing information as entities, their properties, and the relationships between them, typically in the form of a graph. By linking data across different domains, KGs enable machines to understand context, perform reasoning, and support intelligent applications like search, recommendations, and question answering. Some widely used knowledge graphs include DBpedia, which extracts structured content from Wikipedia; Wikidata, a collaboratively curated knowledge base of facts; and YAGO, which integrates data from multiple sources. These popular KGs serve as foundational resources for both research and real-world applications in artificial intelligence and data integration.
