  • An analysis of Twitter corpora and the differences between formal and colloquial tweets 

    González Bermúdez, Meritxell (CEUR-WS.org, 2015)
    Conference report
    Open Access
    This work reviews recent publications addressing the Twitter translation task, and highlights the lack of appropriate corpora that represents the colloquial language used in Twitter. It also discusses the most well-know ...
  • A new subtree-transfer approach to syntax-based reordering for statistical machine translation 

    Khalilov, Maxim; Rodríguez Fonollosa, José Adrián; Dras, Mark (2009-05)
    Conference lecture
    Open Access
    In this paper we address the problem of translating between languages with word order disparity. The idea of augmenting statistical machine translation (SMT) by using a syntax-based reordering step prior to translation, ...
  • An IR-based strategy for supporting Chinese-Portuguese translation services in off-line model 

    Centelles, Jordi; Ruiz Costa-Jussà, Marta; Banchs Martínez, Rafael Enrique; Gelbukh, Alexander (2014-04-01)
    Article
    Restricted access - publisher's policy
    This paper describes an Information Retrieval engine that is used to support our Chinese-Portuguese machine translation services when no internet connection is available. Our mobile translation app, which is deployed on ...

    In recent years, machine translation (MT) research has focused on investigating how hybrid machine translation as well as system combination approachescan bedesigned so that theresulting hybrid translationsshow an improvement ...
  • Automatic normalization of short texts by combining statistical and rule-based techniques 

    Ruiz Costa-Jussà, Marta; Banchs, Rafael E. (2013-03-01)
    Article
    Open Access
    Short texts are typically composed of small number of words, most of which are abbreviations, typos and other kinds of noise. This makes the noise to signal ratio relatively high for this specific category of text. A high ...
