LOD Cloud Quality Assessment

Visualising the Assessed LOD Cloud Datasets against the Intrinsic Category

The visualisation below shows how different datasets fare against each other against the Intrinsic Category metrics. The darker the color of the circle means that it has lower conformance score. Publishers tend to conform to quality issues related to the intrinsic category and this is shown with the high quality value and its moderate distribution. However, data publishers should be more careful with using the right datatyped resources in the domain and range of a property.

Summary Statistics

• Average Conformance: 73%
• Standard Deviation: 13%
• Conformance towards the usage of correct domain or range datatypes should be improved (average conformance ≈ 60%)
