Descriptive Italian Grammar

From Descriptive Annotation to Grammar Specification

The paper presents an architecture for connecting annotated linguistic data with a computational grammar system. Pivotal to the architecture is an annotational interlingua – called the Construction Labeling system (CL) which is notationally very simple, descriptively finegrained, cross-typologically applicable, and formally well-defined enough to map to a state-of-the-art computational model of...

Restructuring Verbs in Italian HPSG Grammar

1 Introduction Restructuring verbs (Rizzi 1982) exhibit certain properties: they trigger clitic climbing, long NP-Movement and auxiliary change. The aim of this paper is to propose a mechanism which is able to give a unitary account of this class of verbs. The analysis will focus mainly on the first two properties and will be carried out within the framework of Head-Driven Phrase Structure Gram...

On si constructions in Italian HPSG Grammar

Building a Large Grammar for Italian

We describe the construction of a large lexicalized tree adjoining grammar for Italian, automatically extracted from an annotated corpus. We first introduce the TUT, a dependency style treebank for Italian, then we illustrate the algorithm that we have designed to extract the grammar, and finally we report two experiments about parsing complexity and coverage of the extracted grammar.

The Lexicon-Grammar of Italian Idioms

This paper presents the Lexicon-Grammar classification of Italian idioms that has been constructed on formal principles and, as such, can be exploited in information extraction. Among MWEs, idioms are those fixed constructions which are hard to automatically detect, given their syntactic flexibility and lexical variation. The syntactic properties of idioms have been formally represented and cod...
