Luzzu Quality Metric Language -- A DSL for Linked Data Quality Assessment [article]

Jeremy Debattista, Christoph Lange, Sören Auer
2015 arXiv   pre-print
Quality assessment requires significant effort and consideration, including the definition of data quality metrics and a process to assess datasets based on these definitions.  ...  The steadily growing number of linked open datasets brought about a number of reservations amongst data consumers with regard to the datasets' quality.  ...  Consequently, if we manage to systematically assess and improve data quality of LOD, many Linked Open Data applications can be better supported and contribute to establishing the 4th Big Data aspect -Veracity  ...

Improving data quality in the linked open data: a survey

A Hadhiatma
2018 Journal of Physics, Conference Series  
Moreover, the term of the ontology refinement means that it copes not only to improve data quality but also to enrich the LOD.  ...  Therefore, it needs (1) a standard for data quality assessment and evaluation which is more appropriate to the LOD; (2) a framework of methods based on statistical relational learning that can improve  ...  Existing RDF data and underlying ontology could be enriched and refined into a new one which aims to improve data quality as well as to enhance ontology expressiveness.  ...
