Re:
hi... i need to compare two ontologies using jena... if i take two
classes, each in a separate ontology. in order to say these two classes are
structurally equivalent, i need to say all the super class for the 2
classes we considered are similar.. can anyone help me for the code

We have the open source project http://code.google.com/p/opensemcq/ that may have a code relevant for the problem (we find similar classes based on pre-specified topological and text similarity based criteria).

Re:
Posted by Mark Fischer <mr...@gmail.com>.
Hey Aarthi,
isMapped is sort of specific to my application. It lets me say something
like,
"http://xmlns.com/foaf/spec/20100809/#" is equivalent to "
http://xmlns.com/foaf/spec/#"
So that if I'm comparing different versions, classes with the same
localName but different
versions for their namespace are still considered equal.
You can ignore this or implement it however you like. I simply used a Map.
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
private Map<String, String> nsRemap;
private boolean isMapped(String thisURI, String thatURI){
if(thisURI.equals(thatURI)) return true;
if(nsRemap == null) return false;
String mapString = nsRemap.get(thisURI);
if(mapString != null && mapString.equals(thatURI)) return true;
return false;
}
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Of course, you'll need to initialize the map somewhere if you want to take
my approach.

Re:

I did something similar a while back.
This doesn't quite do what you want, but it may be close.
I compared inequivalent classes and such as well as super classes.
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
private boolean areEqual(OntClass thisOne, OntClass thatOne){
return areEqual(false, thisOne, thatOne);
}
private boolean areEqual(boolean deep, OntClass thisOne, OntClass thatOne){
if (thisOne.isUnionClass() && thatOne.isUnionClass()) {
return areEqual(thisOne.asUnionClass(), thatOne.asUnionClass());
} else if (thisOne.isIntersectionClass() &&
thatOne.isIntersectionClass()) {
return areEqual(thisOne.asIntersectionClass(),
thatOne.asIntersectionClass());
} else if (thisOne.isComplementClass() && thatOne.isComplementClass()) {
return areEqual(thisOne.asComplementClass(),
thatOne.asComplementClass());
} else if (thisOne.isRestriction() && thatOne.isRestriction()) {
return areEqual(thisOne.asRestriction(), thatOne.asRestriction());
} else if (thisOne.isURIResource() && thatOne.isURIResource()) {
