Hi Mikael,

Disclaimer: I've been using these reasoners (HermiT, Pellet) either through Protégé or as Java libraries (i.e., in Java code), not directly from command line. (So maybe that's the rub here.)

Regarding Eye, you can find the install doc here: http://eulersharp.sourceforge.net/INSTALL. I found this reasoner working quite well via command line - I've used it often.

Hi,

HermiT has a bug giving more false positives that true positives for
entailment: https://github.com/owlcs/hermit-reasoner/issues/9


Pellet and if i remember correctly openllet give java error when trying to compile package: https://github.com/stardog-union/pellet/issues/48


FaCT++: actually just managed to solve issue with missing libs, but
can't find any documentation on how to make config file for reasoning

eye: missing some dependencies and didn't manage to install right ones without documentation.


May I ask which one are you running successfully? Btw I'm using Ubuntu.
