I've wondered about this too. Another thing to consider is using :quant
to separate out the quantifier, e.g. 'nobody/no one' as (o / one :quant (a / any) :polarity -)
.
from amr-guidelines.
Under consensus, we have a few cases of nothing, none and nowhere as a concept.
On the other hand we agreed to split never into ever :polarity -.
So I sympathize with annotators who transform
- nobody -> anybody :polarity -
- no one -> anyone :polarity -
- nothing -> anything :polarity -
- none -> any :polarity -
- nowhere -> anywhere :polarity -
This is less superficial, but appears to be in the minority in current annotations.
Nathan's idea takes this a step further. Cool.
But if we do this (possible in a future version of AMR), we have to be careful with types
- no one -> anyone :polarity - -> any person :polarity -
- nowhere -> anywhere :polarity - -> any location :polarity -
And we will have to pay close attention to the tricky interaction between quant/any/polarity.
I don't think that any is a :quant by itself (unless it's negated). So,
(o / one :quant (a / any) :polarity -) is not as compositional as intended.

Presently, we are leaving quantifiers right on the noun phrases, and we are sticking with the surface pronouns. Hold your nose! (And your noise)
no one (nobody) is sleeping
(s / sleep-01
:arg0 (n / no-one))
i don't like anybody
(l / like-01
:arg0 (i / i)
:arg1 (a / anybody)
:polarity -)
there is nobody that i like
(n / nobody
:arg1-of (l / like-01
:arg0 (i / i)))
everyone is sleeping
(s / sleep-01
:arg0 (e / everyone))
all people are sleeping
(s / sleep-01
:arg0 (p / person
:quant all))
i don't like most people
(l / like-01
:arg0 (i / i)
:polarity -
:arg1 (p / person
:quant (m / most)))
IDEALLY:
"nobody is sleeping" = "there does not exist p such that sleep(p)"
"everyone is sleeping" = "for all p, sleep(p)"
"not everyone is sleeping" = ?
"he never sleeps" = "there is no time t such that (s / sleep :arg0 he :time t)"
"i don't like anybody" = "there does not exist p such that like(i, p)"
"most people ..."
"a few people ..."
"x / y" means "there exists an x, which is an instance of y"
our support for first-order logic is weak.
quantifiers have scope, which logic captures with parenthesis.
nobody should be equal to no one & sometimes equal to anybody...
