Introduction to Knowledge Graphs

This section introduces the concept of knowledge graphs and their applications.

What are Knowledge Graphs?

  • A way of representing semantic information between two entities.
  • Modern applications allow almost any entity you could imagine to be described with anyone.
  • Machines are able to understand how these entities relate to each other, along with shared attributes.
  • Allows us to draw connections between different things in the world around us.

Nodes and Edges

  • A knowledge graph is made up of nodes connected by edges.
  • Nodes describe any object or person or place, and an edge defines the relationship between the nodes.
  • The pair of nodes can be connected by more than one relation if they are related in multiple ways.

Applications of Knowledge Graphs

  • Can build different data sources and bind them together to infer missing facts.
  • Utilize natural language processing (NLP) to construct a view of nodes and edges through a process called semantic enrichment.
  • Commercial applications include question and answer queries, recommended videos, insurance claims, retail product recommendations.
