Owlready2

documentation download stats

Owlready2 is a module for ontology-oriented programming in Python 3. It can manage ontologies and knwoledge graphs, and includes an optimized RDF/OWL quadstore.

Owlready2 can:

  • Import OWL 2.0 ontologies in NTriples, RDF/XML or OWL/XML format
  • Export OWL 2.0 ontologies to NTriples or RDF/XML
  • Manipulates ontology classes, instances and properties transparently, as if they were normal Python objects
  • Add Python methods to ontology classes
  • Perform automatic classification of classes and instances, using the HermiT or Pellet reasoner (included)
  • Load DBpedia or UMLS (for medical terminology, using the integrated PyMedTermino2 submodule)
  • Native support for optimized SPARQL queries
  • Tested up to 1 billion of RDF triples! (but can potentially support more)
  • In addition, the quadstore is compatible with the RDFlib Python module
  • Finally, Owlready2 can also be used as an ORM (Object-Relational mapper) -- as a graph/object database, it beats Neo4J, MongoDB, SQLObject and SQLAlchemy in terms of performances

Owlready has been created by Jean-Baptiste Lamy at the LIMICS reseach lab. It is available under the GNU LGPL licence v3. If you use Owlready in scientific works, please cite the following article:

Lamy JB. Owlready: Ontology-oriented programming in Python with automatic classification and high level constructs for biomedical ontologies. Artificial Intelligence In Medicine 2017;80:11-28

In case of troubles, questions or comments, please use this Forum/Mailing list: http://owlready.306.s1.nabble.com

What can I do with Owlready2?

Load an ontology from a local repository, or from Internet:

>>> from owlready2 import *
>>> onto_path.append("/path/to/your/local/ontology/repository")
>>> onto = get_ontology("http://www.lesfleursdunormal.fr/static/_downloads/pizza_onto.owl")
>>> onto.load()

Create new classes in the ontology, possibly mixing OWL constructs and Python methods:

>>> with onto:
...     class NonVegetarianPizza(onto.Pizza):
...       equivalent_to = [
...         onto.Pizza
...       & ( onto.has_topping.some(onto.MeatTopping)
...         | onto.has_topping.some(onto.FishTopping)
...         ) ]
...       def eat(self): print("Beurk! I'm vegetarian!")

Access ontology class, and create new instances / individuals:

>>> onto.Pizza
pizza_onto.Pizza
>>> test_pizza = onto.Pizza("test_pizza_owl_identifier")
>>> test_pizza.has_topping = [ onto.CheeseTopping(),
...                            onto.TomatoTopping(),
...                            onto.MeatTopping  () ]

Export to RDF/XML file:

>>> test_onto.save()

Perform reasoning, and classify instances and classes:

>>> test_pizza.__class__
onto.Pizza

>>> # Execute HermiT and reparent instances and classes
>>> sync_reasoner()

>>> test_pizza.__class__
onto.NonVegetarianPizza
>>> test_pizza.eat()
Beurk! I'm vegetarian !

Perform SPARQL queries:

>>> list(default_world.sparql("""SELECT * { ?x a owl:Class . FILTER(ISIRI(?x)) }"""))
[[pizza_onto.CheeseTopping], [pizza_onto.FishTopping], [pizza_onto.MeatTopping], [pizza_onto.Pizza], [pizza_onto.TomatoTopping], [pizza_onto.Topping], [pizza_onto.NonVegetarianPizza]]

Access to medical terminologies from UMLS:

>>> from owlready2 import *
>>> from owlready2.pymedtermino2.umls import *
>>> default_world.set_backend(filename = "pym.sqlite3")
>>> import_umls("umls-2018AB-full.zip", terminologies = ["ICD10", "SNOMEDCT_US", "CUI"])
>>> default_world.save()

>>> PYM = get_ontology("http://PYM/").load()
>>> ICD10       = PYM["ICD10"]
>>> SNOMEDCT_US = PYM["SNOMEDCT_US"]

>>> SNOMEDCT_US[186675001]
SNOMEDCT_US["186675001"] # Viral pharyngoconjunctivitis

>>> SNOMEDCT_US[186675001] >> ICD10   # Map to ICD10
Concepts([
  ICD10["B30.9"] # Viral conjunctivitis, unspecified
])
