Knowledge graphs and ontologies are intrinsically linked as ontologies provide the structural framework for knowledge graphs, defining their entities and relationships as described in [1]. Furthermore, knowledge graphs utilize specific ontology-based relationships like 'is-a' and 'has-a' to organize data [2], and construction methods often integrate ontology constraints to ensure validation and consistency [3].

referenceKnowledge graphs are composed of entities (primary objects or concepts represented as nodes), relationships (connections between entities specifying interactions), attributes (properties or characteristics of entities), triples (facts represented as subject-predicate-object), and an ontology (the schema or structure organizing the graph).
