How do you determine whether a triple from a query result has been inferred?

I would like to display inferred triples differently in my UI, but I’m unsure how to programmatically ascertain which triple is from inference and which is raw data. The only way I can think of that might work would be to make a secondary look-up in the raw data graph and compare the difference

How to separate Ontology triples from Instance triples?

schemas too. How do I get the just base model + the inferred triples without the schema data mixed in? Kind regards, Simon Gray Research Officer, Centre for Language Technology, University of Copenhagen

Inference rule selection for dummies?

Hi everyone, I'm on Jena 3.14 experimenting with the built-in OntologySpecs. My main requirement is inferring reverse relations (when applicable). Only the OWL reasoners do this, but they also infer so many more triples which balloons the size of the InfModel so much that it is impossible for m

Re: Precomputing OWL inferences

between man-made, curated triples and some varying set of inferred triples. Is this at all possible to do with Jena? > Den 5. jul. 2021 kl. 10.38 skrev Dave Reynolds : > > On 05/07/2021 08:03, Simon Gray wrote: >> Thank you for that answer, Dave! I think this provides the missing

Precomputing OWL inferences

to wait? I’ve tried calling `rebind` and `prepare`, but they don’t seem to do anything. Kind regards, Simon Gray Research Officer Centre for Language Technology, University of Copenhagen
