article DET /
As can be seen, both morphological word class tags, secondary lexical tags and
syntactic tags are made use of in the filter, underlining the rather hybrid and
idiosyncratic character of traditional pronoun classes.
Traditionally, the Portuguese word forms a, as, o, os would be described either as
definite articles or - when modified by PPs or relative clauses - as demonstrative
pronouns. In my system, they belong to the same word class (DET), but have two
lexically bound secondary tags, 214 and that are then functionally
disambiguated by valency-level CG-rules, which can - from lower level disambiguation
- draw on both syntactic function (3a) and word class context (3b):
(3a) REMOVE (@%art) (NOT 0 @>N) ; #remove definite article reading if not prenominally used
(3b) REMOVE (@%dem) (0 ) (NOT 1 DET-REL OR SPEC-REL OR PRP) ; # remove
demonstrative reading of potential definite articles if the following word is not a relative
pronoun or a preposition
The article tag for the indefinite articles um, uma, uns, umas can be directly filtered
from my DET class, since the necessary ambiguity resolution does not concern syntactic
function, and the secondary (indefinite article) need not be disambiguated once
the word class is determined. This, however, is still a considerable disambiguation task,
as can be seen from the rules in (4), that perform differentiation from the NUM word
class (numerals) necessary for the two singular forms, um and uma..
(4)
ordinary rules:
SELECT ("um" DET) (1C SO-ADJ) ; # um só
SELECT ("um" DET) (-1C ) (NOT 1 VEZ OR PRP-DE/PRP_DET) ; # foi um ano
extraordinário, not: foi um dos ...
SELECT ("um" DET) (1 PRP-DE) (NOT 2 N/V-P) ; # O vice dá uma de galante titular
SELECT ("um" DET) (-1 PRP-DE) (*-2 KOMP-CORR BARRIER NON-
NOMINAL/PRP) (1 N) (2 ) ; # a marca mais agradável dum ano cuja retrospectiva ...
SELECT ("um" NUM) (-1 MAIS) (0 S) ; # mais uma vez
SELECT ("um" NUM) (1C ) (0 S) (NOT 2 ) ; # durava uma semana; not: a marca mais
agradável dum ano cuja retrospectiva ...
SELECT ("um" NUM S) (*2 OUTRO BARRIER CLB LINK NOT 1 N) ; # um em=frente ao outro
SELECT ("um" NUM S) (1 PRP-DE/PRP_DET LINK 0 P) ; # um desses cidadões
SELECT ("um" NUM S) (1C VFIN) ; # um vive, outro morre
214 For these words, implies (definite article), which is the icon used as a set definition and in output filtering.
