A knowledge graph, also known as a semantic network, represents a network of real-world entities—i.e. objects, events, situations, or concepts—and illustrates the relationship between them. This information is usually stored in a graph database and visualized as a graph structure, prompting the term knowledge “graph.”
Moreover, is DBpedia a knowledge graph?
DBpedia is a crowd-sourced community effort to extract structured content from the information created in various Wikimedia projects. This structured information resembles an open knowledge graph (OKG) which is available for everyone on the Web.

What is knowledge graph NLP?

What is knowledge graph reasoning?
In knowledge representation and reasoning, knowledge graph is a knowledge base that uses a graph-structured data model or topology to integrate data. Knowledge graphs are often used to store interlinked descriptions of entities – objects, events, situations or abstract concepts – with free-form semantics.
What is the difference between a graph and a knowledge graph?
The terms are used interchangeably, but they are not necessarily synonymous. While every knowledge graph is a knowledge base, or uses a knowledge base, the key is in the word “graph”. A knowledge graph is organised as a graph, which is not always true of knowledge bases.
