Computational Models of Dialectal Variation and Underlying Linguistic Features

The report illustrates the results of the joint research activity carried out from June 13th to July 4th 2010 at the University of Groningen - Faculty of Arts - Center for Language and Cognition Groningen (CLCG) directed by Prof. John Nerbonne. In particular, it illustrates the application and specialization of the technique of "hierarchical bipartite spectral graph partitioning" (Wieling and Nerbonne, 2010) with respect to the dialectal corpus of the Atlante Lessicale Toscano (\u27Lexical Atlas of Tuscany\u27, henceforth ALT) and discusses achieved results. The analysis focuses on the level of phonetic variation: this is the level of analysis for which an aggregate analysis of the ALT dialectal corpus has provided divergent results compared to the analyses by Giannelli (1976, 2000) and Pellegrini (1977), as documented in Montemagni (2007, 2008). Phonetic variation in Tuscany thus provides a particularly challenging case study to test the potential of this new analysis technique to study models of linguistic variation

Bootstrapping enhanced universal dependencies for Italian

The paper presents an extension of the Italian Universal Dependencies Treebank with an "enhanced" representation level (e-IUDT), aimed at simplifying the information extraction process. The modules developed to semi-automatically build e-IUDT were delexicalized to perform cross-language enhancements: preliminary experiments in this direction led to promising results

The Italian dependency annotated corpus developed for the CoNLL-2007 Shared Task

This document illustrates the Italian dependency annotated corpus developed for the CoNLL-X Shared Task (henceforth referred to as ISST-CoNLL). In particular, it provides information on the background resource, the way the CoNLL Italian resource has been designed and developed, and finally documents the adopted annotation scheme

Harmonization and Merging of two Italian Dependency Treebanks

The paper describes the methodology which is currently being defined for the construction of a "Merged Italian Dependency Treebank'' (MIDT) starting from already existing resources. In particular, it reports the results of a case study carried out on two available dependency treebanks, i.e. TUT and ISST--TANL. The issues raised during the comparison of the annotation schemes underlying the two treebanks are discussed and investigated with a particular emphasis on the definition of a set of linguistic categories to be used as a "bridge'' between the specific schemes. As an encoding format, the CoNLL de facto standard is used

Tecnologie linguistico-computazionali per la valutazione delle competenze linguistiche in ambito scolastico

The presentation will illustrate whether and how linguistic technologies can be used to monitor the language learning process.Se da una lato le tecnologie linguistico-computazionali svolgono un ruolo ormai indiscusso per l\u27accesso al contenuto testuale, sia esso rappresentato dalla conoscenza specifica di un dominio oppure dalla conoscenza linguistica sottostante (es. collocazioni, strutture argomentali, relazioni semantico-lessicali tra parole, ecc.), ci? non appare scontato quando si vada a considerare il loro ruolo nella valutazione della competenza linguistica di apprendenti. La presente comunicazione intende indagare questo interrogativo, in particolare se e in che misura le tecnologie linguistico-computazionali possano costituire un valido ausilio nella valutazione della competenza linguistica italiana di studenti in ambito scolastico

Converting Italian Treebanks: Towards an Italian Stanford Dependency Treebank

The paper addresses the challenge of converting MIDT, an existing dependencybased Italian treebank resulting from the harmonization and merging of smaller resources, into the Stanford Dependencies annotation formalism, with the final aim of constructing a standard–compliant resource for the Italian language. Achieved results include a methodology for converting treebank annotations belonging to the same dependency–based family, the Italian Stanford Dependency Treebank (ISDT), and an Italian localization of the Stanford Dependency scheme
