<strong>Opposites</strong><br />

- cover a very large variety of<br />

phenomena<br />

- use in natural language generation is<br />

hard to make explicit:<br />

how expensive is this book?<br />

vs.<br />

? how cheap is this book?


<strong>Opposites</strong><br />

- probably the one sense relation that is<br />

most readily understood by ordinary<br />

speakers<br />

- most languages seem to have an nonlearned<br />

term for it:<br />

Arabic: ‘aksi; Chinese: tao-fan;<br />

French: contraire;<br />

German: gegensatz; ...


<strong>Opposites</strong><br />

Definition:<br />

Two words are opposites if they have<br />

most semantic characteristics in common<br />

but if they also differ in a significant way<br />

on at least one essential semantic<br />

dimension.<br />

Examples: good:bad, love:hate


<strong>Opposites</strong><br />

various degrees of opposition:<br />

prototypical instances: good:bad,<br />

large:small, true:false, top:bottom<br />

peripheral examples: mother:father,<br />

brother:sister, town:country

Definition:<br />

Complements<br />

Complementaries are a<br />

special class of<br />

opposites which divide<br />

the whole conceptual<br />

space exactly into two<br />

non-overlapping<br />

compartments.


Complements<br />

Examples:<br />

true:false,<br />

dead:alive,<br />

open:shut,<br />

pass:fail (an examination),<br />

male:female,<br />

even:odd


Complements<br />

test:<br />

If one term is denied, the other term has<br />

to be asserted - and vice versa:<br />

This dog is male.<br />

entails and is entailed by<br />

This dog is not female.


Complements<br />

another test:<br />

Denying both terms should be odd.<br />

? The door is neither open nor shut.<br />

? The number is neither even nor odd.


Complements - verbs<br />

four possible types of opposites<br />

reversives: be born:live:die<br />

= continuance of a state vs. change to an<br />

alternative state<br />

interactives: invite:accept:turn down<br />

= relation of the type stimulus-response


Complements - verbs<br />

four possible types of opposites<br />

satisfactive: seek:find<br />

=attempt to do something + successful<br />

performance<br />

counteractive: attack:defend:submit<br />

= aggressive action + active and passive<br />

response


Complements - adjectives<br />

- some are not gradable<br />

? extremely true<br />

? fairly dead<br />

- often one member of the pair is more<br />

readily to be graded:<br />

? slightly shut, ? more shut than before<br />

wide open, more open than before


Overview<br />

opposites<br />

– complements<br />

verbs & adjectives<br />

– antonyms<br />

3 sub-types<br />

– inherentness<br />

– implicit superlatives<br />

– stative verbs<br />

– contrastive aspects


Antonymes<br />

Antonyms do not necessarily partition the<br />

conceptual space into two clearly distinct<br />

parts which cover the whole conceptual<br />

domain, but some overlap or space in<br />

between is possible


Antonymes<br />

Anotymes refer to degrees of some<br />

variable property such as length, speed,<br />

weight, accuracy etc.<br />

Examples: long:short, fast:slow,<br />

easy:difficult, good:bad, hot:cold,<br />

cheap:expensive


Antonymes


Antonymes<br />

antonyms have to be interpreted<br />

comparatively:<br />

small elephant vs. big mouse<br />

reference point: average value within a<br />

class


Antonymes – 3 sub-types<br />

difference between pseudo- and true<br />

comparatives:<br />

It’s short, but it’s longer than the other one.<br />

longer = pseudo comparative<br />

? It’s hot, but it’s colder than yesterday.<br />

colder = true comparative


Antonymes – 3 sub-types<br />

polar antonyms: long:short<br />

(pseudo-comparative corresponding to<br />

each member of a pair)<br />

It’s short, but it’s longer than the other one.<br />

It’s long, but it’s shorter than the other one.<br />

- objectively descriptive


Antonymes – 3 sub-types<br />

overlapping antonyms: good:bad,<br />

clean:dirty<br />

(one member of the pair has a pseudocomparative<br />

and the other one a true<br />

comparative)<br />

John is cruel, but he is kinder than Mary<br />

? Mary is kind, but she is more cruel than John.<br />

- to evaluate


Antonymes – 3 sub-types<br />

equipollent antonyms: hot:cold,<br />

happy:sad<br />

(both members have true comparatives)<br />

? It’s hot, but it’s colder than yesterday.<br />

? It’s cold, but it’s hotter than yesterday.<br />

- referring to sensations, emotions,<br />

subjective reactions


Antonymes – 3 sub-types<br />

polar antonyms:<br />

One member is marked, the other is not;<br />

the unmarked one can be used in a<br />

neutral way:<br />

How long is it?<br />

? How short is it?


Antonymes – 3 sub-types


Antonymes – 3 sub-types<br />

overlapping & equipollent antonyms:<br />

each member of the pair seems to be<br />

autonomous:<br />

How cold is it?<br />

How hot is it?

Overview<br />

opposites<br />

– complements<br />

verbs & adjectives<br />

– antonyms<br />

3 sub-types<br />

– inherentness<br />

– implicit superlatives<br />

– stative verbs<br />

– contrastive aspects


Inherentness<br />

overlapping antonyms:<br />

The scale of merit (good, better)<br />

overlaps with that of badness (bad,<br />

worse), because something bad can be<br />

described as being better than something<br />

worse.


Inherentness<br />

but:<br />

Mary’s headache is worse than John’s.<br />

? John’s headache is better than Mary’s.<br />

There are some lexical items that do not<br />

work with better because their referents<br />

are ‘inherently bad’ (e.g. headache,<br />

depression, failure, storm, earthquake,<br />

flood...)


Inherentness<br />

polar antonyms: no inherentness<br />

Example: dwarfs are inherently short,<br />

but it’s possible to say:<br />

The dwarfs standing at the right side of the tree<br />

are taller than those standing left of it.

– antonyms<br />

3 sub-types<br />

– inherentness<br />

– implicit superlatives<br />

– stative verbs<br />

Implicit superlatives<br />

Some scales have implicit superlatives.<br />

E.g. the scale of size: not only<br />

small:large, but huge:tiny,<br />

enormous:minute<br />

other examples: beautiful:ugly,<br />

brilliant:stupid


Implicit superlatives<br />

distinct properties of implicit superlatives:<br />

resistant to grading: ? very huge<br />

? slightly enormous<br />

can be modified by absolutely:<br />

absolutely huge<br />

absolutely enormous

– inherentness<br />

Stative Verbs<br />

represent psychological states (e.g.<br />

like:dislike)<br />

fully gradable: I quite like it.<br />

neutral area between the opposing<br />

poles:<br />

I neither like nor dislike her – she leaves me<br />

totally indifferent.

Contrastive Aspects<br />

no specific knowledge about the<br />

existence of sub-classes of antonyms in<br />

other languages than English


Contrastive Aspects<br />

one observation: if translated to another<br />

language a pair of antonyms will not<br />

necessarily belong to the same structural<br />

group as the English pair:<br />

English: hot:cold – equipollent<br />

French: chaud:froid – polar


Contrastive Aspects<br />

equipollent (hot:cold):<br />

more objective – “primitive”<br />

polar (long:short) & overlapping<br />

(good:bad):<br />

more subjective – “conceptualised”<br />

- English is relatively subjective.<br />

- Macedonian is very conceptualised,<br />

since all antonyms polar ones.
