Visualising the Assessed LOD Cloud Datasets against the Accessiblity Category

The visualisation below shows how different datasets fare against each other against the Accessibility Category metrics. The darker the color of the circle means that it has lower conformance score. We can see that datasets like dbpedia has a high conformance amongst the other assessed datasets. The assessment identified that a large concentration of low quality values were mostly affected by licensing representation in the data itself.

Summary Statistics

  • Average Conformance: 30%
  • Standard Deviation: 19%
  • Low usage of Machine-Readable Licences (17 out of 131 datasets) and Human-Readable Licences (11 out of 131 datasets)
