Polarity is a category that indicates the distinction between affirmative and negative.
Natural Language
In the UNLarium, polarity may assume two values:
{{#tree:id=nl_polarity|openlevels=0|root=Polarity|
- affirmative (AFM)
- negative (NEG)
}}
Examples
- English
- not = NEG
- never = NEG
- none = NEG
UNL
In UNL, the attribute polarity may assume the following values:
{{#tree:id=unl_polarity|openlevels=0|root=Polarity|
- @yes
- @not
- @maybe
}}
- Affirmative is the default value and must be omitted. The attribute @yes is used only for emphatic affirmative
- I live here = live
- I do live here = live.@yes
- Polarity attributes must be assigned according to the scope of the affirmative or negative
- She didn't come = come.@not
- I don't know whether she came = know.@not (but not
came.@not)
- Polarity attributes must not be informed when lexicalized
- never = never (and not
never.@not) - I never lived here = live (and not
live.@not)
- Double negatives must be rewritten as simple negatives
- I don't know nothing = I don't know anything (know.@not) or I know nothing (know)
Examples
- I live here = live
- I do live here = live.@yes
- I don't live here = live.@not
- Maybe I live here = live.@maybe
