. . . . . "Definition 1. (Problem Definition: Mapping RDF Triples to Quality Issues). Given T a set of RDF triples and Q a set of quality issues, a mapping of triples to quality issues is defined as a partial function φ : T → 2 Q . φ(t) denotes the quality issues associated with t ∈ T . In particular, when φ(t) 6 = ∅ the triple t is considered ‘incorrect’, otherwise it can be affirmed that t is ‘correct’." . . . . . "2019-11-08T18:05:11+01:00"^^ . .
