completeness
This metric measures the interlinking completeness.
This metric measures the property completeness by checking the missing object values for the given predicate and given class of subjects.
This metric measures the property completeness by checking the missing object values for the given predicate and given class of subjects. A user specifies the RDF class and the RDF predicate, then it checks for each pair whether instances of the given RDF class contain the specified RDF predicate.
This metric measures the ratio of the number of classes and relations of the gold standard existing in g, and the number of classes and relations in the gold standard.
This metric measures the interlinking completeness. Since any resource of a dataset can be interlinked with another resource of a foreign dataset this metric makes a statement about the ratio of interlinked resources to resources that could potentially be interlinked.
An interlink here is assumed to be a statement like
<local resource> <some predicate> <external resource>
or
<external resource> <some predicate> <local resource>
Local resources are those that share the same URI prefix of the considered dataset, external resources are those that don't.
