Graph

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.
