OWL 2 EL ontology for semantic Grid information service

Pospishnyi O.S.

Mass deployment of ontologies and application of intelligent systems in general is hampered by the fact, that reasoning algorithms for such systems have a very high computational complexity. While developing our intellectual Grid resource management system, were ontologies play a fundamental role, we faced an unacceptably low performance of reasoning with knowledge bases that consisted of large amount of datatype expressions. In order to ensure an acceptable speed of classification and scalability, we converted our Grid resource ontology to the OWL 2 EL profile and used a modified high-performance OWL reasoner ELK, which allowed for a multiple performance gains.
