    Conference report
    Open Access
    This paper describes a system that jointly parses syntactic and semantic dependencies, presented at the CoNLL-2008 shared task (Surdeanu et al., 2008). It combines online Peceptron learning (Collins, 2002) with a parsing ...
  • A second-order joint Eisner model for syntactic and semantic dependency parsing 

    Lluis Martorell, Xavier; Bott, Stefan Markus; Màrquez Villodre, Lluís (2009)
    Conference lecture
    Restricted access - publisher's policy
    We 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 ...
  • Context-aware machine translation for software localization 

    Muntés Mulero, Víctor; Paladini Adell, Patricia; España Bonet, Cristina; Màrquez Villodre, Lluís (2012)
    Conference lecture
    Open Access
    Software localization requires translating short text strings appearing in user interfaces (UI) into several languages. These strings are usually unrelated to the other strings in the UI. Due to the lack of semantic ...
  • Deep evaluation of hybrid architectures: simple metrics correlated with human judgments 

    Labaka, Gorka; Díaz de Ilarraza Sánchez, Arantza; Sarasola Gabiola, Kepa; España Bonet, Cristina; Màrquez Villodre, Lluís (2011)
    Conference lecture

    España Bonet, Cristina; Labaka, Gorka; Díaz de Ilarraza Sánchez, Arantza; Màrquez Villodre, Lluís; Sarasola, Kepa (2013)
    Conference report
    Open Access
    The process of developing hybrid MT systems is usually guided by an evaluation method used to compare different combinations of basic subsystems. This work presents a deep evaluation experiment of a hybrid architecture, ...
  • Discriminative learning within Arabic statistical machine translation 

    España Bonet, Cristina; Giménez, Jesús; Màrquez Villodre, Lluís (2009-01)
    External research report
    Open Access
    Written 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
    Open Access
    Most 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 ...
  • Hybrid machine translation guided by a rule-based system 

    España Bonet, Cristina; Màrquez Villodre, Lluís; Labaka, Gorka; Díaz de Ilarraza Sánchez, Arantza; Sarasola Gabiola, Kepa (2011)
    Conference lecture
    Open Access
    This paper presents a machine translation architecture which hybridizes Matxin, a rulebased system, with regular phrase-based Statistical Machine Translation. In short, the hybrid translation process is guided by the ...
  • Identifying useful human correction feedback from an on-line machine translation service
