Files are here Prediction_and_kb.zip

The two files can be ready without a problem with rdflib see below

>>> import rdflib
>>> rdflib.Graph().parse("best_pred.owl")
<Graph identifier=N2f70772cfc4741f7bf78bfdef644c864 (<class 'rdflib.graph.Graph'>)>

Any suggestion to solve this problem ?

Hi I assume the file is not found since you using a relative path? ./home/......

[Demirrr]

Thank you for the point.

Yet, this works

./owl2nl.sh -a ./src/test/resources/test_axioms.owl \
            -u false -o ./src/test/resources/test_ontology.owl \
            -t json -s test_out.json -m rule

but this doesn't

./owl2nl.sh -a ./src/test/resources/best_pred.owl \
            -u false -o ./src/test/resources/family.owl \
            -t json -s test_out.json -m rule

where /src/test/resources/ contains best_pred.owland family.owl

[Demirrr]

Oh I guess I might understood the problem. Replacing the following

<owl:Ontology rdf:about="https://dice-research.org/predictions/1705308430.7992284">
  <owl:imports rdf:resource="file://../KGs/Family/family.owl"/>
</owl:Ontology>

with <owl:Ontology rdf:about="http://example.com/asdasda"/> does the trick.

As far as i know, Jena tries to import. Maybe it works when the file exists. I have to test that. Thanks for reporting.

I was wondering whether creating a JAR file for owl2nl script would be a much of a work.

If it is not much work, creating a JAR file and uploading it into https://files.dice-research.org would help you and others to avoid possible future issues. What do yo think ?
