Luzzu is a Quality Assessment Framework for Linked Open Datasets. It is
a generic framework based on the Dataset Quality Ontology (daQ),
allowing users to define their own quality metrics. Luzzu is an
integrated platform that:
- assesses Linked Data quality using a library of generic and
user-provided domain specific quality metrics in a scalable manner;
- provides queryable quality metadata on the assessed datasets;
- assembles detailed quality reports on assessed datasets.
Furthermore, the infrastructure:
- scales for the assessment of big datasets;
- can be easily extended by the 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 facilitating
use-case driven discovery and retrieval.
