Could use GUID like tags as they are instantiated.

Thanks Sir,

I will like to know if it is possible to query a concept ( Ontology Class) given an Instance ?

eg : I have an instance -> ontology how can I look for it Class in the Education Concept to tell someone that in this case ontology is a school-subject

Do you have relevant publication on this domain ?

Thanks

your question seems too general and the answer depends on the API you are using to access your ontology.

https://pythonhosted.org/Owlready2/onto.html

There is a library in python dealing with ontology owlready / owlready2

you can check the publication :

The problem was solve using RDFLib python Library.

Have to acces the Object of the Property "rdf:type"

I highly recommend the kglab - https://derwen.ai/docs/kgl/tutorial/.
