4. def AttributeRichness(ontologyTriples: RDD[Triple]): Double

   

   refers to how much knowledge about classes is inthe schema.

   refers to how much knowledge about classes is inthe schema. The more attributes are defined, the more knowledge the ontol-ogy provides. the number of attributes for all classes divided by the number of classes (C).

5. def ClassCoverage(O1: RDD[Triple], O2: RDD[Triple], Om: RDD[Triple], numberOfMatchedClasses: Int): Double

   

   refers to how many classes in the input ontologies C1+C2 are preserved in the merged ontology Cm excluding matched classes Cmatch.

6. def Compactness(O1: RDD[Triple], O2: RDD[Triple], Om: RDD[Triple]): Double

   

   refers to how much the size of the merged ontology compared to the input ontologies.

   refers to how much the size of the merged ontology compared to the input ontologies. The smaller size of merged ontology, themore the ontology is compacted, e.g. if some resources are removed in order to avoid redundant resources in the merged ontology.

7. def GetQualityAssessmentSheet(O1: RDD[Triple], O2: RDD[Triple], Om: RDD[Triple]): Unit

   

   Get the quality assessment sheet for the input and merged ontologies.

8. def InheritanceRichness(ontologyTriples: RDD[Triple]): Double

   

   refers to how well knowledge is distributed across different levels in the ontology.

   refers to how well knowledge is distributed across different levels in the ontology. the number of sub-classes divided by the sum of the number of classes.

9. def IsolatedElements(ontologyTriples: RDD[Triple]): Double

   

   refers to classes and properties which are defined but not connected to the rest of the ontology, i.e.

   refers to classes and properties which are defined but not connected to the rest of the ontology, i.e. not used. (isolated classes + isolated properties)/(classes + properties)

10. def MissingDomainOrRange(ontologyTriples: RDD[Triple]): Double

    

    refers to missing information about properties.

    refers to missing information about properties. The less of missing information about properties, the more the ontology is complete.

11. def PropertyCoverage(O1: RDD[Triple], O2: RDD[Triple], Om: RDD[Triple], numberOfMatchedProperties: Int): Double

    

    refers to how many relations in the input ontologies P1+P2 are preserved in the merged ontology Pm excluding matched properties Pmatch.

12. def Readability(ontologyTriples: RDD[Triple]): Double

    

    refers to the the existence of human readable descriptions(HRD) in the ontology, such as comments, labels, or description.

    refers to the the existence of human readable descriptions(HRD) in the ontology, such as comments, labels, or description. The more human readable descriptions exist, the more readable the ontology is. HRD / number of resources

13. def Redundancy(O: RDD[Triple]): Double

    

    refers to how many redundant resources exist.

14. def RelationshipRichness(ontologyTriples: RDD[Triple]): Double

    

    refers to the diversity of relations and their position in the ontology.

    refers to the diversity of relations and their position in the ontology. The more relations the ontology has (except \texttt{rdfs:subClassOf} relation), the richer it is. number of object property / (subClassOf + object property)
