Hi,
I want to get the semantic similarity between two classes in ontology, then
I need some parameters for semantic similarity: the depth of a class, the depth
of the ontology tree, the depth of the lowest common ancestor of two classes,
the number of the son classes of a class, the shorest path between two classes.
I have already join Jena to myeclipse, but I couldn't get these above
parameters through Jena. Could you give me some idea?
There are no built-in algorithms for such class hierarchy analysis in Jena.
I'm aware of projects in the past which have built ontology mapping
algorithms on top of Jena and so created libraries for metrics like
these but none of the ones that I know of are now actively maintained.
Maybe others know of more current tools.
