Luzzu: A Quality Assessment Framework for Linked Open Datasets

Luzzu is a Quality Assessment Framework that provides an integrated platform that: (1) assesses Linked Data quality using a library of generic and user-provided domain specific quality metrics in a scalable manner; (2) provides queryable quality metadata on the assessed datasets; (3) assembles detailed quality reports on assessed datasets. Furthermore, we aim to create an infrastructure that:

  • can be easily extended by users by creating their custom and domain-specific pluggable metrics, either by employing a novel declarative quality metric specification language or conventional imperative plugins;
  • employs a comprehensive ontology framework for representing and exchanging all quality related information in the assessment workflow;
  • implements quality-driven dataset ranking algorithms facilit- ating use-case driven discovery and retrieval.
