How to represent Double Negation by automatically modifying AMR?

See original GitHub issue

Hi,

I got one question. Probably just some tips are appreciated. Do you know what I can do to modify AMR using the double negation rule? In this case, one way is to use an antonym argument unhappy-01 to replace happy-01 and then add a :polarity -. But it seems hard to do that automatically if I got many sentences and I did not have a dictionary library that includes the whole antonym argument in AMR. Do you know there is a antonym dictionary library in AMR? Many thanks.

The original sentence is like that.

# ::snt I am happy today.
(h / happy-01
      :ARG1 (ii / i)
      :time (t / today))

The AMR by adding a :polarity - and change the happy-01 to unhappy-01.

# ::snt I'm not unhappy today.
(h / unhappy-01
      :ARG1 (ii / i)
      :time (t / today)
	  :polarity -)

There is none. You might try WordNet (see the NLTK or Wn for Python libraries).
