- class mowl.projection.OWL2VecStarProjector(bidirectional_taxonomy=False, only_taxonomy=False, include_literals=False)[source]
Bases:
ProjectionModelImplementation of projection rules defined in [chen2020b].
Axiom of condition 1
Axiom or triple(s) of condition 2
Projected triple(s)
\(A \sqsubseteq \square r . D\)
\(D \equiv B\left|B_{1} \sqcup \ldots \sqcup B_{n}\right| B_{1} \sqcap \ldots \sqcap B_{n}\)
\(\langle A, r, B\rangle\)
or
\(\square r . D \sqsubseteq A\)
\(\exists r . \top \sqsubseteq A\) (domain)
\(\top \sqsubseteq \forall r . B\) (range)
\(\langle A, r, B_{i}\rangle\) for \(i \in 1, \ldots, n\)
\(A \sqsubseteq \exists r .\{b\}\)
\(B(b)\)
\(r \sqsubseteq r^{\prime}\)
\(\left\langle A, r^{\prime}, B\right\rangle\) has been projected
\(r^{\prime} \equiv r^{-}\)
\(\left\langle B, r^{\prime}, A\right\rangle\) has been projected
\(s_{1} \circ \ldots \circ s_{n} \sqsubseteq r\)
\(\langle A, s_1, C_1\rangle \ldots \langle C_n, s_n, B\rangle\) have been projected
\(B \sqsubseteq A\)
\(-\)
\(\langle B, r d f s: s u b C l a s s O f, A\rangle\)
\(\left\langle A, rdfs:subClassOf^{-}, B\right\rangle\)
\(A(a)\)
\(-\)
\(\langle a, r d f: t y p e, A\rangle\)
\(\left\langle A, r d f: t y p e^{-}, a\right\rangle\)
\(r(a, b)\)
\(-\)
\(\langle a, r, b\rangle\)
- Parameters:
bidirectional_taxonomy (bool, optional) – If
Truethen per each SubClass edge one SuperClass edge will be generated. Default is False.include_literals (bool, optional) – If
Truethe graph will also include triples involving data property assertions and annotations. Default is False.only_taxonomy (bool, optional) – If
True, the projection will only include subClass edges
