Table 1 Metrics as minimal requirements for quality assessment on RDF resources. Modified from [8]
From: Assessing resolvability, parsability, and consistency of RDF resources: a use case in rare diseases
Metric | Definition |
|---|---|
Non-resolvable URIs | Measure the proportion of unique non-resolvable URIs to all unique URIs in an RDF resource. A URI is non-resolvable if it returns an error code (e.g., http 404). |
Non-parsable URIs | Measure the proportion of unique non-parsable URIs to all unique URIs in an RDF resource. A URIs is non-parsable if its media type is indicated as RDF content-type, but its content cannot be parsed as RDF triples. |
Undefined URIs | Measure the proportion of unique, undefined URIs to all unique URIs in an RDF resource. A URI is considered as undefined if it does not exist within the parsed RDF triples resulting from resolving the URI. |
Misplaced classes or properties | 1) Measure the proportion of classes which are incorrectly used as a predicate to all unique classes; or 2) measure the proportion of properties which are incorrectly used as a class to all unique properties. |
Misuse of owl:DatatypeProperty or owl:ObjectProperty | Measure the proportion of misused ‘owl:DatatypeProperty’ (or ‘owl:ObjectProperty’ ) properties to all properties. |
Use of deprecated classes or properties | Measure the proportion of deprecated classes or properties to all unique classes or properties. |
