The World Wide Web represents a tremendous source of knowledge, whose amount constantly increases. Open Data initiatives and the Semantic Web community have emphasized the need to publish data in a structured format based on open standards and ideally linked to other data sources. But that does not necessarily lead to error-free information and data of good quality. It would be of high relevance to have a software component that is capable of measuring the most relevant quality metrics in a generic fashion as well as rating these results.

We therefore present SemQuire, a quality assessment tool for analyzing quality aspects of particular Linked Data sources both in the Open Data context as well as in the Enterprise Data Service context. It is based on open standards such as W3C’s RDF, SPARQL and DQV, and implements as a proof-of-concept a basic set of 55 recommended intrinsic, representational, contextual and accessibility quality metrics. We provide a use case for evaluating SemQuire’s feasibility and effectiveness.
