23.3 Knowledge Graph

A knowledge graph is a graph that captures knowledge in a structural way. The nodes represent different types of entities (people, locations, objects) and the links represent relationships between the nodes. The concept shares ideas from the concept of Frames Graham J. Williams (1989) and Object Oriented Programming, and the Semantic Net.

Entities might be people, paintings, etc, and links relate a person as the painter of a painting, for example.

Entities as countries, people, awards, universities, and links such as graduate, win, citizen, etc, for example
