Dependencias Universales para los treebanks AnCora

The present article describes the conversion of the Catalan and Spanish AnCora treebanks to the Universal Dependencies formalism. We describe the conversion process and assess the quality of the resulting treebank in terms of parsing accuracy by means of monolingual, cross-lingual and cross-domain parsing evaluation. The converted treebanks show an internal consistency comparable to the one shown by the original CoNLL09 distribution of AnCora, and indicate some differences in terms of multiword expression inventory with regards to the already existing UD Spanish treebank. The two new converted treebanks will be released in version 1.3 of Universal Dependencies.Este artículo presenta la conversión de los treebanks AnCora del catalán y el castellano al formalismo de Dependencias Universales (UD). Describimos el proceso de conversión y estimamos la calidad de los treebanks resultantes en términos de sus resultados en análisis sintáctico automático en un esquema monolingüe, en un esquema trans-lingüístico y en un tercero trans-dominio. Los treebanks convertidos muestran un nivel de consistencia interna de anotación comparable a la de los datos originales de la distribución CoNLL09 de AnCora, e indican algunas diferencias en términos del inventario de expresiones polilexemáticas con respecto al anterior treebank del castellano en UD. Los dos nuevos treebanks convertidos serán distribuidos con la versión 1.3 de Dependencias Universales

Overview of the SPMRL 2013 shared task: cross-framework evaluation of parsing morphologically rich languages

This paper reports on the first shared task on statistical parsing of morphologically rich languages (MRLs). The task features data sets from nine languages, each available both in constituency and dependency annotation. We report on the preparation of the data sets, on the proposed parsing scenarios, and on the evaluation metrics for parsing MRLs given different representation types. We present and analyze parsing results obtained by the task participants, and then provide an analysis and comparison of the parsers across languages and frameworks, reported for gold input as well as more realistic parsing scenarios

IMST: A Revisited Turkish Dependency Treebank

In this paper, we present a critical analysis of the dependency annotation framework used in the METU-Sabancı Treebank (MST), and propose new annotation schemes that would alleviate the issues we have identified. Later, we describe our attempt at reannotating the treebank from the ground up using the proposed schemes, and then compare the consistencies of the two versions via cross validation using a dependency parser. According to our experiments, the reannotated version of the original treebank, which we call the ITU-METU-Sabancı Treebank (IMST), demonstrates a labeled attachment score of 75.3% and an unlabeled attachment score of 83.7%, surpassing the corresponding scores of 65.9% and 76.0% for MST by a very large margin.Peer reviewe

New perspectives on cohesion and coherence: Implications for translation

The contributions to this volume investigate relations of cohesion and coherence as well as instantiations of discourse phenomena and their interaction with information structure in multilingual contexts. Some contributions concentrate on procedures to analyze cohesion and coherence from a corpus-linguistic perspective. Others have a particular focus on textual cohesion in parallel corpora that include both originals and translated texts. Additionally, the papers in the volume discuss the nature of cohesion and coherence with implications for human and machine translation.The contributors are experts on discourse phenomena and textuality who address these issues from an empirical perspective. The chapters in this volume are grounded in the latest research making this book useful to both experts of discourse studies and computational linguistics, as well as advanced students with an interest in these disciplines. We hope that this volume will serve as a catalyst to other researchers and will facilitate further advances in the development of cost-effective annotation procedures, the application of statistical techniques for the analysis of linguistic phenomena and the elaboration of new methods for data interpretation in multilingual corpus linguistics and machine translation
