https://perkapp.fbk.eu/helis/ontology/helis_v1.10.owl has non English labels. What is the best way to extract English labels?
>>> from owlready2 import default_world
>>> default_world.set_backend(filename='/tmp/helis_v1.10.sq3')
>>> c=next(default_world.classes())
>>> c.label
['Activity', "Attivita'", 'Attività ']
