Once you have downloaded the code from GitHub you only need to modify the file src/main/java/test/DatasetTestPhase.java to run GADES.
GADES need as inputs:
- A knowledge graph in OWL format.
- Two knowledge graph entities to be compared.
In this example we compare the entities http://purl.org/obo/owl/GO#GO_0006355 and http://purl.org/obo/owl/GO#GO_0006342, which are two classes from the Gene Ontology.
String ontFile = prefix + "goProtein/go.owl";
MyOWLOntology o = new MyOWLOntology(ontFile, ontPrefix.get(prefix), "HermiT");
OWLConcept a = o.getOWLConcept("http://purl.org/obo/owl/GO#GO_0006355");
OWLConcept b = o.getOWLConcept("http://purl.org/obo/owl/GO#GO_0006342");
Set<MyOWLLogicalEntity> anns = new HashSet<MyOWLLogicalEntity>();
anns.add(a);
anns.add(b);
o.setOWLLinks(anns);
Set<OWLLink> neighA = a.getNeighbors();
Set<OWLLink> neighB = b.getNeighbors();
System.out.println(b.similarityIC(a));//.taxonomicSimilarity(a));
OWLRelation r1 = o.getOWLRelation("http://purl.obolibrary.org/obo/RO_0002213");
System.out.println(o.getPropertyChains(r1));
OWLRelation r2 = o.getOWLRelation("http://purl.obolibrary.org/obo/RO_0002211");
System.out.println(o.getPropertyChains(r2));
System.out.println(r1.similarity(r2));
