A Knowledge Graph is fundamentally defined as a structure that represents information using triplets, which consist of a head, relation, and tail {fact:1, fact:7}. These triplets serve as the core building blocks for constructing, evaluating, and querying knowledge graphs {fact:2, fact:3, fact:4, fact:5, fact:6}.

claimThe predicate constraint-based question-answering system (PCQA) presented in 2019 utilizes knowledge graph predicate constraints—triplets consisting of a subject, predicate, and object—to capture connections between questions and answers, thereby simplifying processing and improving results.
formulaIn a knowledge graph, two nodes (e1 and e2) connected by a relation (r1) form a triplet (e1, r1, e2), where e1 is the head entity and e2 is the tail entity.
claimA knowledge graph is a representation of triplets as a graph where edges represent relations and nodes represent entities.

referenceA Knowledge Graph represents knowledge as a set of triplets, where each triplet consists of a Head (Subject), a Relation (Predicate), and a Tail (Object). An example is 'Neurons Lab (Head) is located in (Relation) Europe (Tail).'
A Knowledge-Graph Based LLM Hallucination Evaluation Framework themoonlight.io 1 fact
procedureThe GraphEval framework constructs a Knowledge Graph from LLM output through a four-step pipeline: (1) processing input text, (2) detecting unique entities, (3) performing coreference resolution to retain only specific references, and (4) extracting relations to form triples of (entity1, relation, entity2).
