<h1> Cat: the Category System</h1>
|
|
|
|
The category system is central to the library in the sense
|
|
that the other modules (<tt>Adjective</tt>, <tt>Adverb</tt>, <tt>Noun</tt>, <tt>Verb</tt> etc)
|
|
communicate through it. This means that a e.g. a function using
|
|
<tt>NP</tt>s in <tt>Verb</tt> need not know how <tt>NP</tt>s are constructed in <tt>Noun</tt>:
|
|
it is enough that both <tt>Verb</tt> and <tt>Noun</tt> use the same type <tt>NP</tt>,
|
|
which is given here in <tt>Cat</tt>.
|
|
|
|
Some categories are inherited from [``Common`` Common.html].
|
|
The reason they are defined there is that they have the same
|
|
implementation in all languages in the resource (typically,
|
|
just a string). These categories are
|
|
<tt>AdA, AdN, AdV, Adv, Ant, CAdv, IAdv, PConj, Phr</tt>,
|
|
<tt>Pol, SC, Tense, Text, Utt, Voc, Interj</tt>.
|
|
<p>
|
|
Moreover, the list categories <tt>ListAdv, ListAP, ListNP, ListS</tt>
|
|
are defined on <tt>Conjunction</tt> and only used locally there.
