The relationship between an entity (subject) and a fact about that entity (predicate/object pair), representing real-world facts within a data graph.
A tuple is a fundamental unit of a data graph and represents a real-world fact within a Knowledge Graph. A tuple defines the relationship between an entity (the subject) and a fact about that entity (the predicate/object pair). For example, the fact “Maryland is a state in the United States” is a tuple. Tuples can also include additional information such as context information, statistical data, and metadata about the edges (relationships).
