Conference report
Open AccessWe present a detailed analysis of a graph- based annotation strategy that we employed to annotate a corpus of 11,292 real-world En- glish to Spanish automatic translations with relative (ranking) and absolute ... -
A pipeline for large raw text preprocessing and model training of language models at scale
(Universitat Politècnica de Catalunya, 2021-01-25)
Master thesis
Open Access
Covenantee: Universitat de Barcelona / Universitat Rovira i VirgiliThe advent of Transformer-based (i.e., based on self-attention architectures) language models has revolutionized the entire field of Natural Language Processing (NLP). Once pre-trained on large, unlabelled corpora, we can ... -
A second-order joint Eisner model for syntactic and semantic dependency parsing
(2009)
Conference lecture
Restricted access - publisher's policyWe present a system developed for the CoNLL-2009 Shared Task (Hajic et al., 2009). We extend the Carreras (2007) parser to jointly annotate syntactic and semantic dependencies. This state-of-the-art parser factorizes the ... -
A Speech-based Dialogue System for Household Robots
