Dear Alan,


Complete certainly may have more than one meaning here, however, the use of completeness as Fabian describes is well established in its own field, and we can’t claim exclusive use of words with our preferred meaning. A better approach I think would be to use qualifiers when the senses might be inferred. So logically complete vs factually complete or some such.

Do we need to be careful about the word "completeness" to avoid confusion with the meaning in computational logic in "complete and decidable".   Would we be better using a word such as "sufficient" or "comprehensive" or similar?

Following Vrandecic "Ontology Evaluation" in "Handbook on Ontologies, Second Edition" (with some modification), I think we need to distinguish (among other things) four questions: 

- Accuracy: Is the content of the ontology true? 

- Completeness: Is the domain of interest appropriately covered (this includes terminology as well as axioms)? 

- Conciseness: Does the ontology irrelevant classes, relations, or axioms? 

- Redundancy: Are some axioms redundant because they are already entailed by other axioms?
