Knowledge Graph (KG)

A structured representation of knowledge, typically in the form of a graph, where entities are nodes and relationships between entities are edges. Knowledge graphs organize information in a way that captures the semantic relationships and contextual associations between entities, enabling efficient storage, retrieval, and inference of knowledge. KGs are widely used in various domains, including search engines, recommendation systems, question answering, and semantic web applications. They facilitate the integration of heterogeneous data sources and support complex queries and reasoning tasks, making them valuable tools for representing and leveraging structured knowledge in diverse applications.
