Ontology evaluation criteria in Vrandečić [7]

Criteria	Definition
Accuracy	Does the asserted knowledge in the ontology agree with the expert’s knowledge, which is often measured in terms of precision and recall?
Completeness	Is the domain of interest appropriately covered (i.e., coverage)?
Conciseness	Does the ontology define irrelevant elements with regards to the domain to be covered or redundant representations of the semantics?
Consistency	Does the ontology include or allow for contradictions, which is often measured as the number of terms with inconsistent meaning?
Computational efficiency	How fast can the tools (e.g., reasoners) work with the ontology?
Adaptability	How easy or difficult is it to use an ontology in different contexts? Adaptability often measures coupling (i.e., number of external classes referenced) and cohesion (i.e., modularity of the ontology).
Clarity	How effective can the ontology communicate the intended meaning of the defined terms?
