(LOV) Linked Open Vocabularies. DBpedia.fr. Graph. The core UMBEL ontology now contains about 26,000 reference concepts organized according to 33 super types.


There are more than 60,000 relationships amongst these concepts, resulting in a graph structure of very large size. It is difficult to grasp this graph in the abstract. Thus, using methods earlier described in our use of the Gephi visualization software [1], we present below a dynamic, navigable rendering of this graph of UMBEL core: Note: at standard resolution, if this graph were to be rendered in actual size, it would be larger than 34 feet by 34 feet square at full zoom !!!

Hint: that is about 1200 square feet, or 1/2 the size of a typical American house ! YAGO2 - D5: Databases and Information Systems (Max-Planck-Institut für Informatik) Overview YAGO2s is a huge semantic knowledge base, derived from Wikipedia WordNet and GeoNames.
