------------- |
|
|
.. code-block:: python |
|
|
|
|
|
from ontolearner.ontology import MDO |
|
|
|
|
|
# Initialize and load ontology |
|
|
ontology = MDO() |
|
|
ontology.load("path/to/ontology.OWL") |
|
|
|
|
|
# Extract datasets |
|
|
data = ontology.extract() |
|
|
|
|
|
# Access specific relations |
