Hello everyone:
I have been struggling a lot with a problem that I did not find a solution
for, so hopefully guys can guide me or help me with it.
I have my data (rdfs) store in jena tdb as model and my owl (schema) using
protoge.
Here is the code to merge data and schema:
System.out.println("creting infeer dataset ");
Dataset dataset = TDBFactory.createDataset(data.infereedTDB);
System.out.println("creting OntModel ");
OntModel Infmodel =
ModelFactory.createOntologyModel(PelletReasonerFactory.THE_SPEC,
dataset.getNamedModel(this.URL));
System.out.println("adding schema (OWL) to OntModel");
Infmodel.add(this.owl);
System.out.println("adding data (RDF) to OntModel ");
Infmodel.add(data.tdb);
System.out.println("creting ModelExtractor ");
ModelExtractor ext = new ModelExtractor(Infmodel);
dataset.replaceNamedModel(this.URL, ext.extractModel());
System.out.println("saving infead model");
Infmodel.close();
System.out.println("closing infeed dataset");
dataset.close();
So I have the ability to store my inferred data into new tdb and to reason
or build any rule based on Literal values . For example: this is one triple
that has UMLS_type as a property and I can group all subjects with two or
more UMLS_types for instance.
ddidd:C0007586 | ddids:label
| "Cell Cycle"
ddidd:C0007586 | <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> |
ddids:Pathway
ddidd:C0007586 | ddids:UMLS_type
| "T043"
ddidd:C0007586 |
ddids:x-kegg.pathway | <
http://identifiers.org/kegg.pathway/hsa04110>
However, as you can see from the triple above I have x-kegg.pathway as an
external uri. By default protoge takes it to be object property. What I
cannot do is to write a rule for example to group all subject under same
x-kegg.pathway number since it is external URI. For example, I want to
create a class called sameKEGG that its members has <
http://identifiers.org/kegg.pathway/hsa04110> value for example. BTW, I
can do such a thing easily by SPARQL but I would love to use the reasoner
to make complex rules.
I have been struggling with this for awhile and I frankly appreciate any
comments or feedback.
