PDET stands for predeterminer and is the part of speech of a word which can
|
|
|
occur before a determiner such as half his land or twice the money. The property
|
|
|
(MEAS TR) applied to PDET indicates that a predeterminer can be present with a
|
|
|
measure adverb as in almost all two hundred divers. (DEF TR) signifies that the
|
|
|
determiner must be definite (all the pain is allowable; all a pain is incorrect),
|
|
|
while (DEF FL) is the opposite (such the problem is incorrect, such a problem is
|
|
|
allowable). (DET TR) marks a predeterminer which must be followed by some
|
|
|
determiner. (OF FL) indicates that a predeterminer cannot be followed by of, as
|
|
|
opposed to both of the gnomes. (TYPE A) marks predeterminers which cause
|
|
|
certain quantifier-related prosodic effects. (QUANT A) designates the same usage
|
|
|
for pronouns.
|
|
|
|
|
|
The CASE and NUM attributes on the pronouns refer to case and number in
|
|
|
the usual manner. The TYPE is listed for prosodic reasons. (DETMOD TR) in-
|
|
|
dicates that a pronoun can be modified by a determiner-modifying adverb as in
|
|
|
nearly everyone.
|
|
|
|
|
|
There are four types of determiners. DETW stands for a wh-word determiner.
|
|
|
DETQ signifies a quantified determiner. These are distinguished from the quan-
|
|
|
tifiers (part of speech QUANT) by the fact that they may occur in the same noun
|
|
|
group as an ordinal or integer as in every third Eskimo or any six infants. DET-
|
|
|
MOD has the same meaning here as for pronouns. TYPE and QUANT again are
|
|
|
prosodic indicators. Demonstratives (DEM) and articles (ART) are straightfor-
|
|
|
|
|
|
ward.
|
|
|
The ordinals (ORD) include next and last as well as the ordinal integers.
|
|
|
|
|
|
Quarters, thirds, etc. are listed as ORD (NUM PL) because they can occur in
|
|
|
constructions such as three quarters the money, or two thirds the money. The
|
|
|
feature (DEF TR) on these words indicates that the preceding determiner must be
|
|
|
definite. The quantifiers (QUANT) are usually marked for number agreement and
|
|
|
for definiteness agreement with the preceding determiner.
|
|
|
|
|
|
The modals (MOD) are marked with the attribute AUX which gives prosodic
|
|
|
information. The property (TO TR) indicates that a modal can occur in construc-
|
|
|
tions such as ought to deliver, while (TO BE) designates a word which must ap-
|
|
|
pear with be and to as in was going to abscond. The rest of the BE and HAVE
|
|
|
|
|
|
words have their usual meaning.

4.5 The part-of-speech processor
|
|
|
The part-of-speech processor is part of the DECOMP module in the text-to-speech
|
|
|
|
|
|
system. It computes a part-of-speech set for each word in the input, given the
|
|
|
morph decomposition and the parts of speech of the morphs. Itis based on Allen’s
