Why does Google combine deep learning with a knowledge graph?

A lot of people in the knowledge graph and ontology communities see an ontology as something quite different from AI.

It’s useful to understand why Google combines both in order to understand SEO better.

Knowledge representation is known nowadays as “good old fashioned AI”. It grew out of library sciences and the philosophical discipline of ontology, or the study of being, and dealt with how to classify experience.
