Zusammenfassung
We describe an implemented hybrid reasoning architecture that is used in an
EU-funded project called MUSING (http://www.musing.eu) which is dedicated
towards the investigation of semantic-based business intelligence solutions.
The reasoning platform builds on publicly available software, such as Pellet,
OWLIM, and Jena.
The project uses and extends existing OWL ontologies (e.g., PROTON) and
assumes rule-based reasoning to take place on top of OWL.
We describe the pros and cons of each subsystem w.r.t. the needs we have
encountered during our investigation.
We explain the specific reasoning architecture that is based on a sequence
and a fixpoint computation of three reasoners which we might sloppily write
as Pellet + (OWLIM + Jena)^*.
Pellet is used for checking the initial consisteny of the ontology, whereas
OWLIM and Jena are employed to execute rules outside the expressiveness of
OWL. However, OWLIM is way much faster than Jena, but neither has means to
do numerical comparison nor arithmetic.
We explain our choice why SWRL is not enough and why we believe that
binary OWL properties lead to an unwanted proliferation of objects,
making representation and reasoning extremely complex.
