Abstract. The number of publicly available resources that re-use terms from various OWL ontologies has increased massively over last years, with the pres-ence of Linked Open Data datasets and the growing number of websites that embed now structured data into HTML pages using markup languages such as RDFa, microdata and microformats. In this paper, we describe an approach to exploratory analysis of ontology usage patterns on the Web. We have conducted a case study on usage patterns extraction of GoodRelations ontology vocabulary from an RDFa dataset of the Web Data Commons corpus. For this purpose, we designed and ran experiments using a recently proposed pattern mining method for RDF(s) data: Fr-ONT-Qu. Rather than simple statistics or frequent term co-occurrences, we were able to discover more complex usage patterns of structured form of graph patterns, which express how GoodRelations vocabulary is used. 1
