   This class takes an owl file, loads it into a knowledge base using ontolearn.knowledge_base.KnowledgeBase.
   A refinement operator is used to generate a large number of concepts, from which we filter and retain the shortest
   non-redundant concepts. We export each concept and its instances (eventually positive and negative examples) into
   a json file.
