3. ARGUMENT STRUCTURE
The current version of the italian grammar doesn’t make use of an argument-structure list for
the linking of syntactic and semantic arguments. Such a list (ARGS-ST) will be presumably
adopted in the next version, according to the Matrix redefinition.
3.1. Optionality
The feature OPT bool (introduced in the Matrix at the synsem-min level) is used by lexical
entry types (see "letypes.tdl") in the COMPS list.
Subject of a verb is by now always optional (OPT +)
3.2 Free Order (subj inversion or ellipsis, NP-PP and NP-AP inversion)
For the time being, the Italian grammar doesn't take into account cases of topicalization,
although they are quite frequent in the newsgroup messages domain.
However, some case of relative free order are taken into account, namely the subject
inversion, the NP-PP and the NP-AP inversion in verbal argument structure. We adopt the
strategy of using two lexical rules, which simply deal with the inversion of the elements in the
COMPS list:
