The Norwegian Petroleum Directorate (NPD) is a governmental organisation whose main objective is to contribute to maximize the value that society can obtain from the oil and gas activities.The initial dataset that we use are the NPD Fact Pages, which contains information regarding the petroleum activities on the Norwegian continental shelf. The ontology, the query set, and the mappings to the dataset have all been developed at the University of Oslo, and are freely available online. Next we provide more details on each of these items. The –Ontop– Team developed a Data generator and a Framework for this benchmark. In addition, we slightly modified the ontology, the mappings, and the query set by removing minor mistakes, restricting the ontology to the OWL QL profile, and adding missing mappings.
It is freely available at online.
