Negative adjetives doesn't work for all the preposition indicated on the documentation

In the javadoc for NegationFSM.java is indicated that
"recognizes "A B ..." where A is unremarkable, unlikely, or negative and B is of, in, for, or with"

That was no correct for my tests (bellow). Attached the AE used:

.... "Negative of cancer".... Polarity = -1 OK
.... "Negative in cancer" .....Polarity = 1 KO
.... "negative for swelling" ..... Polarity = 1 KO

So
