The IULA Treebank

Abstract

Comunicació presentada al 8th International Conference on Language Resources and Evaluation (LREC'12), celebrat del 21 al 27 de maig de 2012 a Istanbul, Turquia.This paper describes on-going work for the construction of a new treebank for Spanish, The IULA Treebank. This new resource will contain about 60,000 richly annotated sentences as an extension of the already existing IULA Technical Corpus which is only PoS tagged. In this paper we have focused on describing the work done for defining the annotation process and the treebank design principles. We report on how the used framework, the DELPH-IN processing framework, has been crucial in the design principles and in the bootstrapping strategy followed, especially in what refers to the use of stochastic modules for reducing parsing overgeneration. We also report on the different evaluation experiments carried out to guarantee the quality of the already available results.This work was co-funded by the Ramón y Cajal program of the Spanish Ministerio de Ciencia e Innovación, the EU UNER - Competitiveness and Innovation Framework Program, METANET (CIP-PSP-270893), and the UPFIULA PhD grant program. We wish to thank also to Stephan Oepen for his assistance in using the DELPH-IN environment and Lluís Padró for his assistance in the significance calculation
