A Reasoning Broker Framework for OWL

Abstract. Semantic applications that utilise OWL ontologies can benefit from a broad range of OWL reasoning systems, which allow for the inference of implicit knowledge from explicitly given facts and axioms. Different OWL reasoners, however, specialise in different reasoning problems or kinds of ontologies, and hence perform differently in certain reasoning scenarios. This paper presents a reasoning broker framework, which connects to different existing reasoning systems and intelligently delegates reasoning requests. The behaviour of the broker is controlled by exchangeable and configurable broker strategies featuring selection and parallelisation of reasoners, centralised caching, simulated anytime reasoning, and various other potential features. A first experiment shows performance improvement for a sequence of queries compared to the use of different single reasoners.
