Visualising the Assessed LOD Cloud Datasets against the Representational 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. Results show sufficient good quality and a moderate distribution. However, in this case, data publishers should make sure to follow LD principles and were possible re-use existing terms by looking for schemas and ontologies in services such as linked open vocabularies or swoogle

Summary Statistics

  • Average Conformance: 63%
  • Standard Deviation: 14%
  • Data publishers should re-use more existing terms (average conformance ≈ 34%)
