SHARK: A Test-Driven Framework for Design and Evolution of Ontologies.

In the Semantic Web, the sharing and reuse of knowledge are made possible by ontologies which establish common vocabularies and semantic interpretations of terms. Over the last years, the LOD cloud has been growing substantially in size of each ontology and the total number of objects. In order to ensure a certain level of data quality, several methods have been proposed so far, with different characteristics and approaches, demanding the composition of different tools to ensure a full validation and continuous integration with hosting solutions. In this paper, we present SHARK, a single framework capable to test an ontology using formally pre-defined guidelines or custom SHACL tests, and can also be used for continuous testing during the ontology development process.
