I'm doing some project which is based on ontology.I want to identify semantic of the text that has entered by user.
Is there any possible way to fulfill my task dealing with ontology through jena?
Jena doesn't do Natural Language Processing. You want to look at APIs like Zemanta or OpenCalais, or tools like GATE.
kurzum
You might be looking for something like this: http://nlp2rdf.org
The other answers are still correct: Jena is not NLP. But with NLP2RDF you can query NLP tool output with Jena.
