The knowledge graph/base is converted into triples of the form: individual_i —role_j—> concept_k or individual_i —role_j—> individual_k and stored in a txt file for the computation of embeddings.

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.
