DBpedia Mappings Quality Assessment

The root of schema violations for RDF data generated from (semi-)structured data, often derives from mappings, which are repeatedly applied and specify how an RDF dataset is generated. The DBpedia dataset, which derives from Wikipedia infoboxes, is no exception. To mitigate the violations, we proposed in previous work to validate the mappings which generate the data, instead of validating the generated data afterwards. In this work, we demonstrate how mappings validation is applied to DBpedia. DBpedia mappings are automatically translated to RML and validated by RDFUnit. The DBpedia mappings assessment can be frequently executed, because it requires significantly less time compared to validating the dataset. The validation results become available via a user-friendly interface. The DBpedia community takes them into consideration to refine the DBpedia mappings or ontology and thus, increase the dataset quality.
