.. code-block:: python

    from ontolearner.ontology import SPDocument

    # Initialize and load ontology
    ontology = SPDocument()
    ontology.load("path/to/ontology.OWL")

    # Extract datasets
    data = ontology.extract()

    # Access specific relations
    term_types = data.term_typings
    taxonomic_relations = data.type_taxonomies
    non_taxonomic_relations = data.type_non_taxonomic_relations
