06. Very basic Grammar of Italian author DeepThought
9 SEMANTIC ROLES - SYNTACTIC FUNCTIONS LINKING In the italian-grammar (according to the strategy described and adopted by the Norsk group)
we have introduced some functional categories (SUBJECT, DIROBJ, INDIROBJ, OBL1...).
The functional categories are attributes of a type qval which is the value of a feature QVAL in
qval-cat:
qval-cat := cat & [QVAL qval].
The linking is done
i) in synsem types between semantic arguments and indices of functional categories
ii) in cat types between functional categories and syntactic arguments
E.g.:
i)
subj-arg1-verb := lex-synsem &
[ LOCAL [ CAT.QVAL.SUBJECT synsem &
[ LOCAL.CONT.HOOK.INDEX #1],
KEYS.KEY.ARG1 #1 ] ].
ii)
subj-verb-cat := verb-cat &
[ VAL.SUBJ < #1 >,
QVAL.SUBJECT #1 ].
The functional category OBL1 is used for oblique PPs like "a mio fratello" [to my brother] in "il
libro appartiene a mio fratello" [the book belongs to my brother]. For verbs like "appartenere"
(intransitive verbs whit PP complement) in italian-grammar we use the subj-arg1-verb above
and following linking types:
obl1-handle := lex-synsem &
[ LOCAL [ CAT.QVAL.OBL1 synsem &
[ LOCAL.CONT.HOOK.LTOP #1],
KEYS.KEY.LBL #1 ] ].
intrans-ppnoun-verb-cat := intrans-verb-cat &
[ VAL.COMPS < #1 >,
QVAL intrans-qval & [OBL1 #1] ].
intrans-verb-cat := subj-verb-cat & [HEAD.TRANS -].
As an example, the composed synsem for the verb "appartenere" [belong] contains the
following information (as far as they concern the linking):
lex-synsem := subj-arg1-verb & obl1-handle &
[ LOCAL [ CAT intrans-ppnoun-verb-cat &
[ HEAD verb,
VAL [ SUBJ < #1 >,
COMPS < #2 > ],
QVAL [ SUBJECT #1 & [ LOCAL.CONT.HOOK.INDEX #3 ],
OBL1 #2 & [ LOCAL.CONT.HOOK.LTOP #4 ] ] ],
KEYS.KEY arg1-rel &
[ LBL #4, PRED "appartenere_rel", ARG1 #3 ] ] ].
