Ontology of Social Service Needs

Title: Ontology of Social Service Needs
URI: http://ontology.eil.utoronto.ca/gci/csse/ossn.owl
Version: 1.0

The following evaluation results have been generated by the RESTFul web service provided by OOPS! (OntOlogy Pitfall Scanner!).

It is obvious that not all the pitfalls are equally important; their impact in the ontology will depend on multiple factors. For this reason, each pitfall has an importance level attached indicating how important it is. We have identified three levels:

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.

Evaluation results

P02. Creating synonyms as classes1 case detected. Minor

Several classes whose identifiers are synonyms are created and defined as equivalent (owl:equivalentClass) in the same namespace. This pitfall is related to the guidelines presented in [2], which explain that synonyms for the same concept do not represent different classes.

This pitfall affects to the following ontology elements:

"http://ontology.eil.utoronto.ca/GCI/CSSE/OSSN.owl#MHGoalPhoneEsteem"^^xsd:anyURI

P13. Inverse relationships not explicitly declared5 cases detected. Minor

This pitfall appears when any relationship (except for those that are defined as symmetric properties using owl:SymmetricProperty) does not have an inverse relationship (owl:inverseOf) defined within the ontology.

This pitfall affects to the following ontology elements:

P34. Untyped class37 cases detected. Important

An ontology element is used as a class without having been explicitly declared as such using the primitives owl:Class or rdfs:Class. This pitfall is related with the common problems listed in [8].

This pitfall affects to the following ontology elements:
