This is an API to the user of the resource grammar
|
|
for adding lexical items. It gives functions for forming
|
|
expressions of open categories: nouns, adjectives, verbs.
|
|
</P>
|
|
<P>
|
|
Closed categories (determiners, pronouns, conjunctions) are
|
|
accessed through the resource syntax API, <CODE>Structural.gf</CODE>.
|
|
</P>
|
|
<P>
|
|
The main difference with <CODE>MorphoEng.gf</CODE> is that the types
|
|
referred to are compiled resource grammar types. We have moreover
|
|
had the design principle of always having existing forms, rather
|
|
than stems, as string arguments of the paradigms.
|
|
</P>
|
|
<P>
|
|
The structure of functions for each word class <CODE>C</CODE> is the following:
|
|
first we give a handful of patterns that aim to cover all
|
|
regular cases. Then we give a worst-case function <CODE>mkC</CODE>, which serves as an
|
|
escape to construct the most irregular words of type <CODE>C</CODE>.
|
|
However, this function should only seldom be needed: we have a
|
|
separate module <CODE>IrregularEng</CODE>, which covers all irregularly inflected
|
|
words.
|
|
</P>
|
|
<P>
|

The following modules are presupposed:

To abstract over gender names, we define the following identifiers.

<PRE>

Gender : Type ;

To abstract over number names, we define the following.

<PRE>
|

Number : Type ;
|

singular : Number ;
|

plural : Number ;

To abstract over case names, we define the following.

<PRE>
|

Case : Type ;
|
|

nominative : Case ;

genitive : Case ;

The regular function captures the variants for nouns ending with
|
|
<I>s</I>,<I>sh</I>,<I>x</I>,<I>z</I> or <I>y</I>: <I>kiss - kisses</I>, <I>flash - flashes</I>;

<I>fly - flies</I> (but <I>toy - toys</I>),

regN : Str -> N ;

In practice the worst case is just: give singular and plural nominative.

mk2N : (man,men : Str) -> N ;

All nouns created by the previous functions are marked as

<CODE>nonhuman</CODE>. If you want a <CODE>human</CODE> noun, wrap it with the following

|
function:

<H3>Compound nouns</H3>

<P>

All the functions above work quite as well to form compound nouns,

such as <I>baby boom</I>.
|

</P>
|
|
<A NAME="toc5"></A>
|
|
<H3>Relational nouns</H3>
|

<P>

Relational nouns (<I>daughter of x</I>) need a preposition.

<PRE>
|

mkN2 : N -> Preposition -> N2 ;
|
|
</PRE>
|

<P></P>

The most common preposition is <I>of</I>, and the following is a

shortcut for regular relational nouns with <I>of</I>.

<PRE>

regN2 : Str -> N2 ;

Use the function <CODE>mkPreposition</CODE> or see the section on prepositions below to
|
|
form other prepositions.
|

</P>
|

<P>

Three-place relational nouns (<I>the connection from x to y</I>) need two prepositions.

<H3>Relational common noun phrases</H3>

In some cases, you may want to make a complex <CODE>CN</CODE> into a

relational noun (e.g. <I>the old town hall of</I>).

<H3>Proper names and noun phrases</H3>

<P>
|

Proper names, with a regular genitive, are formed as follows
|

</P>

<PRE>
|
|
regPN : Str -> Gender -> PN ; -- John, John's
|
|
</PRE>
|

<P></P>

Sometimes you can reuse a common noun as a proper name, e.g. <I>Bank</I>.

<PRE>
|
|
nounPN : N -> PN ;
|
|
</PRE>
|

<P></P>

To form a noun phrase that can also be plural and have an irregular
|

genitive, you can use the worst-case function.

<H2>Adjectives</H2>
|
|
<P>
|
|
Non-comparison one-place adjectives need two forms: one for
|
|
the adjectival and one for the adverbial form (<I>free - freely</I>)
|
|
</P>
|
|
<PRE>
|
|
mkA : (free,freely : Str) -> A ;
|
|
</PRE>
|
|
<P></P>
|
|
<P>
|
|
For regular adjectives, the adverbial form is derived. This holds
|
|
even for cases with the variation <I>happy - happily</I>.
|
|
</P>
|
|
<PRE>
|
|
regA : Str -> A ;

<A NAME="toc9"></A>
|

<H3>Two-place adjectives</H3>
|
|
<P>
|
|
Two-place adjectives need a preposition for their second argument.
|
|
</P>
|
|
<PRE>
|
|
mkA2 : A -> Preposition -> A2 ;
|
|
</PRE>
|

<P></P>

Comparison adjectives may two more forms.
|

ADeg : Type ;

mkADeg : (good,better,best,well : Str) -> ADeg ;
|

</PRE>

<P></P>
|
|
<P>
|

The regular pattern recognizes two common variations:
|
|
<I>-e</I> (<I>rude</I> - <I>ruder</I> - <I>rudest</I>) and
|
|
<I>-y</I> (<I>happy - happier - happiest - happily</I>)

|
|
regADeg : Str -> ADeg ; -- long, longer, longest
|
|
</PRE>
|
|
<P></P>
|
|
<P>
|
|
However, the duplication of the final consonant is nor predicted,
|
|
but a separate pattern is used:
|
|
</P>
|
|
<PRE>
|
|
duplADeg : Str -> ADeg ; -- fat, fatter, fattest
|
|
</PRE>
|
|
<P></P>
|

<P>

If comparison is formed by <I>more, //most</I>, as in general for//
|
|
long adjective, the following pattern is used:
|
|
</P>
|
|
<PRE>
|
|
compoundADeg : A -> ADeg ; -- -/more/most ridiculous
|
|
</PRE>
|

From a given <CODE>ADeg</CODE>, it is possible to get back to <CODE>A</CODE>.

<A NAME="toc10"></A>
|
|
<H2>Adverbs</H2>
|
|
<P>
|
|
Adverbs are not inflected. Most lexical ones have position
|
|
after the verb. Some can be preverbal (e.g. <I>always</I>).
|
|
</P>
|
|
<PRE>
|
|
mkAdv : Str -> Adv ;
|

mkAdV : Str -> AdV ;
|

</PRE>

<P></P>
|

Adverbs modifying adjectives and sentences can also be formed.

mkAdA : Str -> AdA ;

<P></P>

<A NAME="toc11"></A>
|
|
<H2>Prepositions</H2>
|
|
<P>
|
|
A preposition as used for rection in the lexicon, as well as to
|
|
build <CODE>PP</CODE>s in the resource API, just requires a string.
|
|
</P>
|
|
<PRE>
|

mkPreposition : Str -> Preposition ;

mkPrep : Str -> Prep ;

<A NAME="toc12"></A>
|
|
<H2>Verbs</H2>
|
|
<P>
|
|
Except for <I>be</I>, the worst case needs five forms: the infinitive and
|
|
the third person singular present, the past indicative, and the
|
|
past and present participles.
|
|
</P>
|

<PRE>

mkV : (go, goes, went, gone, going : Str) -> V ;
|

</PRE>
|

<P></P>
|

<P>
|

The regular verb function recognizes the special cases where the last
|
|
character is <I>y</I> (<I>cry - cries</I> but <I>buy - buys</I>) or <I>s</I>, <I>sh</I>, <I>x</I>, <I>z</I>

regDuplV : Str -> V ;

<P></P>

<P>
|
|
There is an extensive list of irregular verbs in the module <CODE>IrregularEng</CODE>.
|
|
In practice, it is enough to give three forms,
|
|
e.g. <I>drink - drank - drunk</I>, with a variant indicating consonant
|
|
duplication in the present participle.
|

</P>

<H3>Two-place verbs</H3>

Two-place verbs need a preposition, except the special case with direct object.

Three-place (ditransitive) verbs need two prepositions, of which

the first one or both can be absent.
