Databases, APIs, and machine learning algorithms
What do knowledge graphs and ontologies have in common in terms of representation?
They are both based on RDF triples
What are the three main components of a knowledge graph?
Edges, nodes, and labels
In the context of a knowledge graph, what does an edge represent?
The relationship between the nodes
How does a knowledge graph differ from a knowledge base?

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.
Test your understanding of knowledge graphs, also known as semantic networks, and their components including nodes, edges, and labels. Explore the representation of real-world entities and their relationships in graph databases.
