 YEAR = {2018}, 
 ABSTRACT = {Detection and correction of errors and inconsistencies in "gold treebanks" are becoming more and more central topics of corpus annotation. The paper illustrates a new incremental method for enhancing treebanks, with particular emphasis on the extension of error patterns across different textual genres and registers. Impact and role of corrections have been assessed in a dependency parsing experiment carried out with four different parsers, whose results are promising. For both evaluation datasets, the performance of parsers increases, in terms of the standard LAS and UAS measures and of a more focused measure taking into account only relations involved in error patterns, and at the level of individual dependencies.},

 YEAR = {2015}, 
 ABSTRACT = {Shared task evaluation campaigns represent a well established form of competitive evaluation, an important opportunity to propose and tackle new challenges for a specific research area and a way to foster the development of benchmarks, tools and resources. The advantages of this approach are evident in any experimental field, including the area of Natural Language Processing. An outlook on state-of-the-art language technologies for Italian can be obtained by reflecting on the results of the recently held workshop "Evaluation of NLP and Speech Tools for Italian", EVALITA 2014. The motivations underlying individual shared tasks, the level of knowledge and development achieved within each of them, the impact on applications, society and economy at large as well as directions for future research will be discussed from this perspective.},

 YEAR = {2015}, 
 ABSTRACT = {In this paper we address the challenge of combining existing CoNLL-compliant dependency-annotated corpora with the final aim of constructing a bigger treebank for the Italian language. To this end, we defined amethodology formapping different annotation schemes, based on: (i)The analysis of similarities and differences of considered source and target dependency annotation schemes; (ii) The analysis of the performance of state of the art dependency parsers trained on the source and target treebanks; (iii) The mapping of the source annotation scheme(s) onto a set of target (possibly underspecified) data categories. This methodology was applied in two different case studies. The first one was aimed at constructing a "Merged Italian Dependency Treebank" (MIDT) starting from existing Italian dependency treebanks, namely TUT and ISST-TANL. The second case study, still ongoing, consists in the conversion of the MIDT resource into the Stanford Dependencies de facto standard with the final aim of developing an "Italian Stanford Dependency Treebank" (ISDT).},

 TITLE = {Less is More? Towards a Reduced Inventory of Categories for Training a Parser for the Italian Stanford Dependencies}, 
 YEAR = {2014}, 
 ABSTRACT = {Stanford Dependencies (SD) represent nowadays a de facto standard as far as dependency annotation is concerned. The goal of this paper is to explore pros and cons of different strategies for generating SD annotated Italian texts to enrich the existing Italian Stanford Dependency Treebank (ISDT). This is done by comparing the performance of a statistical parser (DeSR) trained on a simpler resource (the augmented version of the Merged Italian Dependency Treebank or MIDT+) and whose output was automatically converted to SD, with the results of the parser directly trained on ISDT. Experiments carried out to test reliability and effectiveness of the two strategies show that the performance of a parser trained on the reduced dependencies repertoire, whose output can be easily converted to SD, is slightly higher than the performance of a parser directly trained on ISDT. A non-negligible advantage of the first strategy for generating SD annotated texts is that semi-automatic extensions of the training resource are more easily and consistently carried out with respect to a reduced dependency tagset. Preliminary experiments carried out for generating the collapsed and propagated SD representation are also reported.},

 ABSTRACT = {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.},
