contrast

contrast-01 (AMR annotation guidance)

Contrastive conjunctions such as but, while, whereas, prepositions such as in contrast to and the adverbials such as however, on the other hand are rendered using the concept contrast-01:

Example: I like classical music, but John likes jazz .
     (c / contrast-01
           :ARG1 (l / like-01
                 :ARG0 (i / i)
                 :ARG1 (m / music
                       :mod (c2 / classics)))
           :ARG2 (l2 / like-01
                 :ARG0 (p / person :wiki - :name (n / name :op1 "John"))
                 :ARG1 (j / jazz)))

The example above also captures the sentences

I like classical music, whereas John likes jazz .
While I like classical music, John likes jazz .
I like classical music, in contrast to John who likes jazz .
I like classical music. John, however, likes jazz .
On the one hand, I like classical music. On the other hand, John likes jazz .
My liking of classical music contrasts with John's liking of jazz .

contrast-01 is symmetric, i.e. the arguments of contrast-01 can typically be swapped without changing the meaning:
I like classical music, whereas John likes jazz. = John likes jazz, whereas I like classical music.

Note that in some cases such as in ``It started to rain, but the game continued anyway.'' but signals a :concession rather than a contrast-01.
