    • An efficient algorithm to find the best state sequence in HSMM 

      Bonafonte Cávez, Antonio; Ros Majó, Xavier; Mariño, José B. (1993)
      Conference report
      Open Access
      Hidden Markov Modeling (HMM) techniques have been applied successfully to speech analysis. However, it has been claimed [1-7] that a major weakness of HMM is that the state duration probability density functions (SDPDF) ...
    • Improving a Catalan-Spanish statistical translation system using morphosyntactic knowledge 

      Farrús, Mireia; Ruiz Costa-Jussà, Marta; Poch, Marc; Hernández, Adolfo; Mariño, José B. (2009)
      Conference report
      Open Access
      In this paper, a human evaluation of a Catalan-Spanish Ngram-based statistical machine translation system is used to develop specific techniques based on the use of grammatical categories, lexical categorisation and text ...

      Esta comunicación describe el desarrollo del traductor estadístico N-II entre catalán y castellano. Para mejorar la calidad del sistema, se llevó a cabo un riguroso análisis lingüístico. Este ha permitido plantear ...
    • Out-of-vocabulary word modelling and rejection for keyword spotting 

      Lleida Solano, Eduardo; Mariño, José B.; Salavedra Molí, Josep; Bonafonte Cávez, Antonio; Monte Moreno, Enrique (International Speech Communication Association (ISCA), 1993)
      Conference report
      Restricted access - publisher's policy
      This paper presents a combination of out-of-vocabulary (OOV) word modeling and rejection techniques in an attempt to accept utterances embedding a keyword and reject utterances with nonkeywords. The goal of this research ...
    • UPC-BMIC-VDU system description for the IWSLT 2010: testing several collocation segmentations in a phrase-based SMT system 

      Henriquez, Carlos A; Ruiz Costa-Jussà, Marta; Daudaravicius, Vidas; Banchs, Rafael E.; Mariño, José B. (2010)
      Conference report
      Open Access
      This paper describes the UPC-BMIC-VMU participation in the IWSLT 2010 evaluation campaign. The SMT system is a standard phrase-based enriched with novel segmentations. These novel segmentations are computed using statistical ...
    • Using collocation segmentation to augment the phrase table 

      Henriquez, Carlos A; Ruiz Costa-Jussà, Marta; Daudaravicius, Vidas; Banchs Martínez, Rafael Enrique; Mariño, José B. (Association for Computational Linguistics, 2010)
      Conference report
      Open Access
      This paper describes the 2010 phrase-based statistical machine translation system developed at the TALP Research Center of the UPC1 in cooperation with BMIC2 and VMU3. In phrase-based SMT, the phrase table is the main tool ...
