How can the filtering option of sparql be done?

[ABHISHEKVALSAN]

As of now there are only triples inside WHERE{}. Including this filtering can increase the semantics in the search.
eg) List the details of Actors other than Tom Cruise?
which filters Tom Cruise and displays the result of other actors.
Implementing this is a great achievement against keyword based which will only details of Tom Cruise which is opposite of what the user wants.
