Hi Jiba and other members, I have problem with my sparql query. Can you help me, please?

Hi,

I think there is a problem in you SPARQL query: you should have a single SELECT in the query. If they are independent SELECT, you must execute each of them separately.

If they are not independent, you have to combine them, e.g.:
      inter = list(my_world2.sparql('''
PREFIX onto: <file:/C:/Users/Pasquale%20Bonasia/Downloads/OntoPharma/base_paziente.owl#>
SELECT ?p ?q ?g ?s {
onto:''' + file + ''' onto:fenilchetonuria ?p .
onto:''' + file + ''' onto:diabete ?q .
onto:''' + file + ''' onto:lattosio ?g .
onto:''' + file + ''' onto:glutine ?s . }'''))

Hi,

This error means that the entity "file:/C:/Users/Pasquale%20Bonasia/Downloads/OntoPharma/base_paziente.owl#BNSRNN97E48A893O" has not been found. There is probably an error in the IRI.

Notice that you should avoid using filename (file:..) as IRI, since some tools do not support it well. I suggest to use plain URL (http://...)
