Hi Jeremy The DBpedia extract consist of the file dbpedia_3.5.1.owl , containing the dbpedia taxonomy (which is the hierarchy of classes and properties) and the file dbpedia_instances.nt containing the instances. Instances are the actual objects that you want to recognize in the textual materials. For example - specific persons, organizations, locations etc. Classes are how these objects are grouped and queried.
The statement that Aristotle is a Philosopher should be present in the dbpedia_instances.nt file. Please make sure that you include it in your setup and it is loaded in OWLIM. All the best.
