static as_pykeen(edges, create_inverse_triples=True, entity_to_id=None, relation_to_id=None)

This method transform a set of edges into an object of the type pykeen.triples.triples_factory.TriplesFactory. This method is intended to be used for PyKEEN methods.

Parameters:

• edges (list of Edge) – List of edges.

• create_inverse_triple (bool, optional) – Whether to create inverse triples. Defaults to True

Return type:

pykeen.triples.triples_factory.TriplesFactory

Added in version 0.1.0: This method is available to transform graph edges obtained from ontologies into PyKEEN triples.

astuple()

static getEntitiesAndRelations(edges)

Deprecated since version 0.1.0: Use get_entities_and_relations instead

static get_entities_and_relations(edges)

Parameters:

edges (Edge) – list of edges

Returns:

Returns a 2-tuple containing the list of entities (heads and tails) and the list of relations

Return type:

(list of str, list of str)

Changed in version 1.0.2: Method return type changed to tuple of lists
