    Study Notes

    Ontology and Knowledge Graphs

    • Events at Madison Square Garden in the ontology example are distinguished by their temporal and spatial aspects.
    • RDF (Resource Description Framework) is an example of a widely adopted ontology.

    Knowledge Graph Infrastructure

    • The technological infrastructure that supports the organization of knowledge is the Semantic Web.

    Representation in Knowledge Graphs and Ontologies

    • Knowledge graphs and ontologies have in common the use of symbolic representations, such as entities and relationships, to represent knowledge.

    Components of a Knowledge Graph

    • The three main components of a knowledge graph are: • Entities (nodes) • Relationships (edges) • Properties (attributes)

    Edges in Knowledge Graphs

    • An edge in a knowledge graph represents a relationship between two entities.

    Knowledge Graph vs. Knowledge Base

    • A knowledge graph differs from a knowledge base in that a knowledge graph is a graph-structured data model, whereas a knowledge base is a more general term that can include various formats.

    Ontology Function in Knowledge Graphs

    • The primary function of an ontology in the context of knowledge graphs is to provide a shared vocabulary and conceptualization of a domain that defines the relationships between entities.
