What is a knowledge graph in data science?

A Knowledge Graph is a set of datapoints linked by relations that describe a domain, for instance a business, an organization, or a field of study.

Not every RDF graph is a knowledge graph. For instance, a set of statistical data, e.g. the GDP data for countries, represented in RDF is not a KG. A graph representation of data is often useful, but it might be unnecessary to capture the semantic knowledge of the data.

What is the Ontotext Knowledge Graph?
