Hi Simon,

Thank you very much for your help.

I am trying to fix the concurrentModification error.

Another thing, sometimes I found duplicate result for CELOE alg.

 I am attaching screenshot and conf files here.

[cid:3429310e-61d5-4b32-a34d-c7e7ff828b91]

Here result 5, 6 and 7 the lines are same.

I am also attaching the conf file and ontology file

Is there any option to remove duplicate answer?

With Regards,

Hello Sarker,

thanks for your continued interest in DL-Learner. Currently, the
parallel approaches are still under development. If you want to
contribute to DL-Learner, feel free to send in a Pull Request to fix
the issue you mentioned.

The CELOE algorithm is an anytime algorithm. That means, the top
results may (or may not) improve if you let it run for a longer time.
There is no easy way to tell how long you need to run it before you
will see the top results that you want to see.

You can turn off the time limit by setting maxExecutionTimeInSeconds to
0 and you can then decide to stop the algorithm either by limiting the
number of expression tests (maxClassExpressionTests) or by using the
noise criterion.

You can also try different reasoner components to see if it can speed
up the process.

Take care,
Simon
