Isnt this log output redundant with the one in the end of getUnsatisfiableObjectProperties?

Thanks @matentzn - yes indeed. Fixed in a new commit.

Sorry for the long delay with this. The code looks good and I got major speed improvements in my tests. Thanks! |

Resolves #1096
docs/have been added/updated - N/Amvn verifysays all tests passmvn sitesays all JavaDocs correctCHANGELOG.mdhas been updatedSummary
Here, I've modified the way the reasoner validate step checks for unsatisfiable object properties.
Before, an algorithm was implemented (by @cmungall in #133) that was needed for reasoners (like Elk) that don't support computation of the object-property hierarchy. That method is maintained here, but wrapped in a new method
ReasonerHelper.getUnsatisfiableObjectProperties(), which uses the old technique only for reasoners that don't report that they can pre-compute the object-property hierarchy.Reasoners that can pre-compute that hierarchy use a new simpler technique: computation of the object-property hierarchy, followed by checking of the bottom node for any named object-properties other than the OWL bottomObjectProperty - those are unsatisfiable.
Regardless of the technique used, the method returns the unsatisfiable properties to the main validate() method, where they are reported as before.
Testing
I've updated the tests for unsat properties (added as part of #133) to check behavior under the HermiT and Elk reasoners, as representative examples of reasoners that use each of the two main branches of
getUnsatisfiableObjectProperties()(before, the tests only covered use of Elk).
