DBpedia Classes Node Link Diagram
This experiment displays the graph of the classes of DBpedia. Each node is a class (e.g., Person, Organisation, Event, Place, Species) while each link represents the amount of triples between the entities of the classes it connects.
Given a node, for instance the class Person, it is important to specify that it represents all the entities having as class (rdf:type) Person without any of its subclasses. That is, each instance is represented only with the most specific class it is classified in the DBpedia hierarchy (ontology).
