Evaluation results


There are three levels of importance in pitfalls according to their impact on the ontology:
  • Critical It is crucial to correct the pitfall. Otherwise, it could affect the ontology consistency, reasoning, applicability, etc.
  • Important Though not critical for ontology function, it is important to correct this type of pitfall.
  • Minor It is not really a problem, but by correcting it we will make the ontology nicer.

Pitfalls detected:


Ontology elements (classes, object properties and datatype properties) are created isolated, with no relation to the rest of the ontology.

• This pitfall appears in the following elements:
http://wikiba.se/ontology#Value
http://wikiba.se/ontology#BestRank
http://wikiba.se/ontology#Reference
http://wikiba.se/ontology#Entity
http://wikiba.se/ontology#PropertyType
http://wikiba.se/ontology#GeoAutoPrecision
http://wikiba.se/ontology#Dump

Object and/or datatype properties without domain or range (or none of them) are included in the ontology.

• This pitfall appears in the following elements:
http://wikiba.se/ontology#qualifierValue
http://wikiba.se/ontology#referenceValueNormalized
http://wikiba.se/ontology#claim
http://wikiba.se/ontology#qualifier
http://wikiba.se/ontology#qualifierValueNormalized
http://wikiba.se/ontology#statementValueNormalized
http://wikiba.se/ontology#statementValue
http://wikiba.se/ontology#badge
http://wikiba.se/ontology#statementProperty
http://wikiba.se/ontology#referenceValue
http://wikiba.se/ontology#directClaim
http://wikiba.se/ontology#novalue
http://wikiba.se/ontology#reference
http://wikiba.se/ontology#wikiGroup

Tip: Solving this pitfall may lead to new results for other pitfalls and suggestions. We encourage you to solve all cases when needed and see what else you can get from OOPS!

This pitfall consists in declaring neither the ontology URI nor the xml:base namespace. If this is the case, the ontology namespace is matched to the file location. This situation is not desirable, as the location of a file might change while the ontology should remain stable, as proposed in [12].

*This pitfall applies to the ontology in general instead of specific elements.

Suggestions or warnings:


The domain and range axioms are equal for each of the following object properties. Could they be symmetric or transitive?

According to the highest importance level of pitfall found in your ontology the conformace bagde suggested is "Critical pitfalls" (see below). You can use the following HTML code to insert the badge within your ontology documentation:
