OWL 2 EL is one of the tractable proles of the Web Ontology Language (OWL) which is a W3C-recommended standard. OWL 2 EL provides sucient expressivity to model large biomedical ontologies as well as streaming data such as trac, while at the same time allows for ecient reasoning services. Existing reasoners for OWL 2 EL, however, use only a single machine and are thus constrained by memory and computational power. At the same time, the automated generation of ontological information from streaming data and text can lead to very large ontologies which can exceed the capacities of these reasoners. We thus describe a distributed reasoning system that scales well using a cluster of commodity machines. We also apply our system to a use case on city trac data and show that it can handle volumes which cannot be handled by current single machine reasoners.

R2R curates digital data and documentation generated by environmental sensor systems installed on vessels from the U.S. academic research fleet, with support from the NSF Oceanographic Technical Services and Arctic Research Logistics Programs. BCO-DMO human-curates and maintains data and metadata including biological, chemical, and physical measurements and results from projects funded by the NSF Biological Oceanography, Chemical Oceanography, and Antarctic Organisms & Ecosystems Programs. These two repositories have a strong connection, and document several thousand U.S. oceanographic research expeditions since the 1970’s. Recently, R2R and BCO-DMO have made their metadata collections available as Linked Data, accessible via public SPARQL endpoints. In this paper, we report on these datasets. %B Proceedings of the 1st International Diversity++ Workshop co-located with the 14th International Semantic Web Conference (ISWC 2015), Bethlehem, Pennsylvania, USA, October 12, 2015 %I CEUR-WS.org %V 1501 %P 15-24 %8 10/2015 %G eng %0 Journal Article %J AI Magazine %D 2012 %T Reports of the AAAI 2012 Conference Workshops %A Vikas Agrawal %A Jorge Baier %A Kostas E.
