What is a (Knowledge) Graph?

For the start of our video series on Knowledge Graphs, we look at the meaning and practical use of the term "Knowledge Graph" and, in the second part of the video, recall some basic terms and data structures that pop up when talking about graphs in mathematics and computer science.

The practical examples come later in the course. Neo4j is one type of graph database discussed further on to study its implementation of knowledge graphs.
