This is an API for 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>MorphoGer.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 <A HREF="../../german/IrregGer.gf"><CODE>IrregGer</CODE></A>
|
|
which covers irregularly inflected verbs.

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

Gender : Type ;

neuter : Gender ;

To abstract over case names, we define the following.

Case : Type ;

nominative : Case ;

accusative : Case ;

genitive : Case ;

To abstract over number names, we define the following.

<PRE>
|

Number : Type ;

singular : Number ;

Worst case: give all four singular forms, two plural forms (others + dative),
|
|
and the gender.

<P></P>

<P>

The regular heuristics recognizes some suffixes, from which it
|
|
guesses the gender and the declension: <I>e, ung, ion</I> give the
|
|
feminine with plural ending <I>-n, -en</I>, and the rest are masculines
|
|
with the plural <I>-e</I> (without Umlaut).

The 'almost regular' case is much like the information given in an ordinary
|
|
dictionary. It takes the singular and plural nominative and the
|
|
gender, and infers the other forms from these.

Relational nouns need a preposition. The most common is <I>von</I> with
|

the dative. Some prepositions are constructed in <A HREF="StructuralGer.html">StructuralGer</A>.

variations such as <I>teuer - teurer</I>, <I>böse - böser</I>.
