Abstract

Abstract. The Optique project aims at developing an end-to-end system for semantic data access to Big Data in industries such as Statoil ASA and Siemens AG. In our demonstration we present the first version of the Optique system customised for the Norwegian Petroleum Directorate’s FactPages, a publicly available dataset relevant for engineers at Statoil ASA. The system provides different options, including visual, to formu-late queries over ontologies and to display query answers. Optique 1.0 offers installation wizards that allow to extract ontologies from rela-tional schemata, extract and define mappings connecting ontologies and schemata, and align and approximate ontologies. Moreover, the system offers highly optimised techniques for query answering. 1
