Boosting applied to word sense disambiguation
Escudero Bakx, Gerard; Màrquez Villodre, Lluís; Rigau Claramunt, German (2000-01)
Report de recerca
Accés obertIn this paper we apply Schapire and Singer's AdaBoost.MH boosting algorithm to the Word Sense Disambiguation (WSD) problem. Initial experiments on a set of 15 selected polysemous words show that the boosting approach ... -

Discriminative learning within Arabic statistical machine translation
España Bonet, Cristina; Giménez, Jesús; Màrquez Villodre, Lluís (2009-01)
Report de recerca
Accés obertWritten Arabic is a especially ambiguous due to the lack of diacritisation of texts, and this makes the translation harder for automatic systems that do not take into account the context of phrases. Here, we use a standard ... -
Document-level machine translation as a re-translation process
Martínez Garcia, Eva; España Bonet, Cristina; Màrquez Villodre, Lluís (2014-09-22)
Article
Accés obertMost of the current Machine Translation systems are designed to translate a document sentence by sentence ignoring discourse information and producing incoherencies in the final translations. In this paper we present some ... -
Exploiting diversity of margin-based classifiers
Romero Merino, Enrique; Carreras Pérez, Xavier; Màrquez Villodre, Lluís (2003-12)
Report de recerca
Accés obertAn experimental comparison among Support Vector Machines, AdaBoost and a recently proposed model for maximizing the margin with Feed-forward Neural Networks has been made on a real-world classification problem, namely ... -

Joint arc-factored parsing of syntactic and semantic dependencies
Lluis Martorell, Xavier; Carreras Pérez, Xavier; Màrquez Villodre, Lluís (2013-05)
Article
Accés restringit per política de l'editorialIn this paper we introduce a joint arc-factored model for syntactic and semantic dependency parsing. The semantic role labeler predicts the full syntactic paths that connect predicates with their arguments. This process ... -
