Jul 3, 2022 · Knowledge graphs and ontologies are both parts of a knowledge representation but really address different aspects. An ontology formally defines the concepts (the cognitive elements) of a specific domain, usually via defining properties including “is-a” relationships between concepts and other necessary attributes needed to differentiate concepts for a given purpose. The recent proliferation of knowledge graphs (KGs) coupled with incomplete or partial information, in the form of missing relations (links) between entities, has fueled a lot of research on knowledge base completion (also known as relation prediction). Several recent works suggest that convolutional neural … Knowledge Graph¶ A knowledge graph uses a graph based data model to store details about entities, the relationships between those entities, and groupings or categorizations of those entities.
