Example 3 (Incoherent ontology) Covid-19 vInfectionDisease (4) Covid-19 v:InfectionDisease (5) is incoherent because COVID19 is unsatisfiable in O since it included to two disjoint sets.

WebNov 21, 2024 · More substantively, there are set theories which permit (indeed, require) self-containing sets which are known to be consistent relative to theories we have high degrees of faith in. For example, the theory ZFC - Regularity + Aczel's antifoundation axiom is consistent if ZFC is, and proves the existence of self-containing sets. WebA DL-based ontology (or ontology) O =(T ,A) consists of a set T of concept axioms (TBox) and role axioms, and a set A of assertional axioms (ABox). Concept axioms have the form C D where C and D are (possibly complex) concept descrip-tions, and role axioms are expressions of the formR S,whereR and S are (possibly complex) role descriptions.
For example, an ontology O= {A⊑B,A⊑¬B} is incoherent because Ais un-satisfiable in O.
