Hi,
I have a relatively large OWL file (~50MB) I have created as OntModel.OWL_MEM.
Today I tried to bind it with an OWL reasoner using the following code:
Reasoner reasoner = ReasonerRegistry.getOWLReasoner();
reasoner = reasoner.bindSchema(my50MBModel);
And it took forever for the binding process and it did not even return before I
got disappointed and stopped the process.
I wonder if I am missing anything here? Is there any faster way of defining the
model as an inferece model? What should I expect as average query time on this
model then?
Reasoning time is totally dependent on the nature of your data. A small
ontology can be extremely expensive to reason over.
As a default for the rule based reasoners use the OWL Micro
configuration. It does most of what the fuller configurations do and is
a lot cheaper.
I trust you are running in-memory and not trying to reason over a TDB or
SDB model.
If you need complete DL reasoning or if OWL Micro is too slow then use
Pellet or a commercial solution.
