A list is shown of the characteristics of the 10 graphs constituting the NTNU dataset. Reported in this table are, for each graph: the number of triples, the number of classes (the basic units in CCO), the maximum number of super classes for a class in the graph (Max #sup), the number of super classes averaged over all the classes (Avg #sup), the number of relations (predicates between two classes) and the number of distinct relation types. For technical reasons the analysis of the super class statistics was performed on random selections of 10000 classes.
