Hello,
I had a question about the SPINInferences.run operation. For some reason,
when I pass an OntModel in as the first parameter (i.e. the model to be
queried) the operation takes a LONG time to complete. But when I pass in a
Model, that (I think) is the equivalent of the full OntModel, it is very fast.
For example, I have an OntModel (ontModel) that I would like to run the SPIN
Rules on to generate the inferred triples into it. Currently, I have to copy
the complete OntModel into a Model using the following code:
Model model = ModelFactory.createDefaultModel();
model.notifyEvent(GraphEvents.startRead);
try {
model.add(ontModel);
} finally {
model.notifyEvent(GraphEvents.finishRead);
}
Then, I can call SPINInference.run on the Model...
SPINInferences.run(model, spinInfModel, _spinRulesClass2QueryMap,
initialTemplateBindings, exp, _spinRuleStats, true,
inferenceType.inferenceProp(),
comparator, null);
and it runs very fast. However, if I try to cut the copy out of the equation
and just pass in the OntModel directly to SPINInferences.run...
SPINInferences.run (ontModel, spinInfModel, _spinRulesClass2QueryMap,
initialTemplateBindings, exp, _spinRuleStats, true,
inferenceType.inferenceProp(),
comparator, null);
It runs very slowly. Any ideas on what's going on here?
So,
