<h1> Noun: Nouns, noun phrases, and determiners</h1>

<h2> Noun phrases</h2>
|
||||
The three main types of noun phrases are
|
||||
- common nouns with determiners
|
||||
- proper names
|
||||
- pronouns
|
||||
<p>
|
||||
<p>
|
||||
<pre>
|
||||
fun
|
||||
DetCN : Det -> CN -> NP ; -- the man
|
||||
UsePN : PN -> NP ; -- John
|
||||
UsePron : Pron -> NP ; -- he
|
||||
</pre>
|
||||
|
||||
Pronouns are defined in the module [``Structural`` Structural.html].
|
||||
A noun phrase already formed can be modified by a <tt>Predet</tt>erminer.
|
||||
<pre>
|
||||
PredetNP : Predet -> NP -> NP; -- only the man
|
||||
</pre>
|
||||
|
||||
A noun phrase can also be postmodified by the past participle of a
|
||||
verb, by an adverb, or by a relative clause
|
||||
<pre>
|
||||
PPartNP : NP -> V2 -> NP ; -- the man seen
|
||||
AdvNP : NP -> Adv -> NP ; -- Paris today
|
||||
RelNP : NP -> RS -> NP ; -- Paris, which is here
|
||||
</pre>
|
||||
|
||||
Determiners can form noun phrases directly.
|
||||
<pre>
|
||||
DetNP : Det -> NP ; -- these five
|
||||
</pre>
|
||||
|
||||
<h2> Determiners</h2>
|
||||
The determiner has a fine-grained structure, in which a 'nucleus'
|
||||
quantifier and an optional numeral can be discerned.
|
||||
<pre>
|
||||
DetQuant : Quant -> Num -> Det ; -- these five
|
||||
DetQuantOrd : Quant -> Num -> Ord -> Det ; -- these five best
|
||||
</pre>
|
||||
|
||||
Whether the resulting determiner is singular or plural depends on the
|
||||
cardinal.
|
||||
All parts of the determiner can be empty, except <tt>Quant</tt>, which is
|
||||
the <i>kernel</i> of a determiner. It is, however, the <tt>Num</tt> that determines
|
||||
the inherent number.
|
||||
<pre>
|
||||
NumSg : Num ;
|
||||
NumPl : Num ;
|
||||
NumCard : Card -> Num ;
|
||||
</pre>
|
||||
|
||||
<tt>Card</tt> consists of either digits or numeral words.
|
||||
<pre>
|
||||
data
|
||||
NumDigits : Digits -> Card ; -- 51
|
||||
NumNumeral : Numeral -> Card ; -- fifty-one
|
||||
</pre>
|
||||
|
||||
The construction of numerals is defined in [Numeral Numeral.html].
|
||||
A <tt>Card</tt> can be modified by certain adverbs.
|
||||
<pre>
|
||||
fun
|
||||
AdNum : AdN -> Card -> Card ; -- almost 51
|
||||
</pre>
|
||||
|
||||
An <tt>Ord</tt> consists of either digits or numeral words.
|
||||
Also superlative forms of adjectives behave syntactically like ordinals.
|
||||
<pre>
|
||||
OrdDigits : Digits -> Ord ; -- 51st
|
||||
OrdNumeral : Numeral -> Ord ; -- fifty-first
|
||||
OrdSuperl : A -> Ord ; -- warmest
|
||||
</pre>
|
||||
|
||||
Definite and indefinite noun phrases are sometimes realized as
|
||||
neatly distinct words (Spanish <i>un, unos ; el, los</i>) but also without
|
||||
any particular word (Finnish; Swedish definites).
|
||||
<pre>
|
||||
IndefArt : Quant ;
|
||||
DefArt : Quant ;
|
||||
</pre>
|
||||
|
||||
Nouns can be used without an article as mass nouns. The resource does
|
||||
not distinguish mass nouns from other common nouns, which can result
|
||||
in semantically odd expressions.
|
||||
<pre>
|
||||
MassNP : CN -> NP ; -- (beer)
|
||||
</pre>
|
||||
|
||||
Pronouns have possessive forms. Genitives of other kinds
|
||||
of noun phrases are not given here, since they are not possible
|
||||
in e.g. Romance languages. They can be found in <tt>Extra</tt> modules.
|
||||
<pre>
|
||||
PossPron : Pron -> Quant ; -- my (house)
|
||||
</pre>
|
||||
|
||||
Other determiners are defined in [Structural Structural.html].
|
||||
<h2> Common nouns</h2>
|
||||
Simple nouns can be used as nouns outright.
|
||||
<pre>
|
||||
UseN : N -> CN ; -- house
|
||||
</pre>
|
||||
|
||||
Relational nouns take one or two arguments.
|
||||
<pre>
|
||||
ComplN2 : N2 -> NP -> CN ; -- mother of the king
|
||||
ComplN3 : N3 -> NP -> N2 ; -- distance from this city (to Paris)
|
||||
</pre>
|
||||
|
||||
Relational nouns can also be used without their arguments.
|
||||
The semantics is typically derivative of the relational meaning.
|
||||
<pre>
|
||||
UseN2 : N2 -> CN ; -- mother
|
||||
Use2N3 : N3 -> N2 ; -- distance (from this city)
|
||||
Use3N3 : N3 -> N2 ; -- distance (to Paris)
|
||||
</pre>
|
||||
|
||||
Nouns can be modified by adjectives, relative clauses, and adverbs
|
||||
(the last rule will give rise to many 'PP attachment' ambiguities
|
||||
when used in connection with verb phrases).
|
||||
<pre>
|
||||
AdjCN : AP -> CN -> CN ; -- big house
|
||||
RelCN : CN -> RS -> CN ; -- house that John bought
|
||||
AdvCN : CN -> Adv -> CN ; -- house on the hill
|
||||
</pre>
|
||||
|
||||
Nouns can also be modified by embedded sentences and questions.
|
||||
For some nouns this makes little sense, but we leave this for applications
|
||||
to decide. Sentential complements are defined in [Verb Verb.html].
|
||||
<pre>
|
||||
SentCN : CN -> SC -> CN ; -- question where she sleeps
|
||||
</pre>
|
||||
|
||||
<h2> Apposition</h2>
|
||||
This is certainly overgenerating.
|
||||
<pre>
|
||||
ApposCN : CN -> NP -> CN ; -- city Paris (, numbers x and y)
|
||||
|
||||
}
|
||||
</pre>
