|
|
"you have", "he has", "they have had", "we will have" and so on — from the
|
|
<a href="../inflections-module/index.html" class="internal">inflections</a> module. However, we won't necessarily want to recognise all of
|
|
those forms in sentences in the source text. For example, Inform only looks

at present tense forms of verbs in the third person, or at imperative forms.

|
|
</p>
|
|
|
|
<p class="commentary">A particular challenge of parsing natural language is to decide the most likely
|
|
word in a sentence to be its primary verb. (The verb in "Heatwave Bone Breaks
|
|
Clog Hospital" is not "to break".) This is especially challenging when the
|
|
noun phrases can't be understood since they refer to things not yet created.
|
|
In Inform, for example, "Peter wears a felt hat" might be the only reference
|
|
anywhere in the source text to either Peter or the hat, which must each be
|
|
created in response to this sentence, and therefore can't be used to
|
|
understand it.
|
|
</p>
|
|
|
|
<p class="commentary">The model we use is to sort verb usages into "tiers", each with a numerical
|
|
"priority", which is a non-negative number. Tier 0 verb usages are never
|
|
recognised. (This does not make them useless: Inform can generate adaptive
|
|
text using them, and they can exist as run-time values in Inform.) Otherwise,
|
|
the lower the priority number, the more likely it is that this verb is meant.
|
|
If two usages belong to the same tier, the earlier in a sentence is preferred.

Inform's linguistic model is not subtle enough to distinguish the difference,

"He is being difficult" doesn't quite mean "He is difficult", which is the

<p class="commentary firstcommentary"><a id="SP7_1" class="paragraph-anchor"></a><b>§7.1. </b>The sequence of registration is important here, and it's done this way to
|
|
minimise false readings due to overlaps. We take future or other exotic
|
|
tenses (say, the French past historic) first; then the perfect tenses,
|
|
then the imperfect; within that, we take negated forms first, then positive;
|
|
within that, we take present before past tense; within that, we run through
|
|
the persons from 1PS to 3PP.
|
|
</p>
|
|
|
|
<p class="commentary">Moreover, we need to group together identical wordings, so that each is
|
|
registered only once, but with an accumulated grammatical usage marker.
|
|
For example, consider the regular English verb "to carry". Of the six present
|
|
tense active voice forms, only one — "carries" — uniquely identifies its
|
|
number and person (i.e., as third person singular); the other five are all
|
|
"carry". So we make two registrations, one with a <a href="1-sc.html#SP9" class="internal">grammatical_usage</a>
|
|
containing a single linguistic constant, the other with one containing five.
|
|
</p>
|
|
|
|
<p class="commentary">We do this by accumulating a to-do list of forms we are interested in —
|
|
callback functions can tell us to ignore certain forms — and the worst-case
|
|
scenario is if every imaginable form is different, so the to-do list needs
|
|
to be this long just in case:

For example, "carry" first person singular present tense is equivalent to
|
|
the same thing in the second person, and so on. The priority for an equivalence
|
|
class is the maximum priority for any of its members; this ensures, for example,

|
that "carry" (1ps) which has priority 0 will not hold back "carry" (3pp) which

needs to have priority 1.

Parsing source text against verb usages. </b>Given a particular VU, and a word range <span class="extract"><span class="extract-syntax">w1</span></span> to <span class="extract"><span class="extract-syntax">w2</span></span>, we test whether the
|
|
range begins with but does not consist only of the text of the VU. We return

the first word after the VU text if it does (which will therefore be a

word number still inside the range), or \(-1\) if it doesn't.

</p>
|

|
<p class="commentary">It is potentially quite slow to test every word against every possible verb,
|
|
even though there are typically fairly few verbs in the S-grammar, so we
|
|
confine ourselves to words flagged in the vocabulary as being used in verbs.
