L'àmbit tecnològic del centre és el processament automàtic del llenguatge, tant en forma oral com escrita, amb l'objectiu d'ajudar a superar les barreres lingüístiques, facilitant la interacció entre persones, entre persones i dispositius, i l'accessibilitat a la informació multilingüe.
Tecnologies de la llengua són aquelles relacionades amb la creació, la gestió i la utilització de tecnologia i de recursos lingüístics (diccionaris, gramàtiques, etc.) per construir sistemes informàtics capaços de comprendre, interpretar i generar les diverses maneres que tenim els humans per comunicar-nos.
En el pla científic, aquesta activitat es basa en disciplines com ara l'aprenentatge automàtic, el processament de la senyal, la lingüística de corpus, l’enginyeria lingüística o el processament del llenguatge natural escrit o parlat. En el pla quotidià, s’inclou en un ventall ampli d’aplicacions cada cop més habituals: cercadors intel·ligents, assistents virtuals, sistemes automàtics d’atenció.

  • Analytic performance evaluation of cumulant-based arma system identification methods 

    Rodríguez Fonollosa, José Adrián; Vidal Manzano, José (IEEE IEEE PRESS, 1993)
    Text en actes de congrés
    Accés obert
    The authors perform an analytic study of some cumulant-based methods for estimating the AR parameters of ARMA processes. The analysis includes new AR identifiability results for pure AR process and the analytic performance ...
  • Blind multiuser detection with probabilistic algorithms - application to underwater communications 

    Antón Haro, Carles; Rodríguez Fonollosa, José Adrián; Zvonar, Zaran; Rodríguez Fonollosa, Javier (IEEE IEEE, 1997)
    Text en actes de congrés
    Accés obert
    In this paper, two probabilistic adaptive algorithms for jointly detecting active users in a DS-CDMA system are compared. The first one, which is based on the theory of hidden Markov models (HMM) is proposed within the ...
  • Frequency averaging: a useful multiwindow spectral analysis approach 

    Nadeu Camprubí, Climent; Padrell, Jaume; Esquerra Llucià, Ignasi (IEEE IEEE, 1997)
    Text en actes de congrés
    Accés obert
    The multiwindow approach is a meaningful framework for nonparametric spectral estimation. It also encompasses several conventional methods as WOSA and frequency-averaged periodogram. Recently, some authors claimed that the ...
  • Blind multiuser identification and detection in cdma systems 

    Rodríguez Fonollosa, Javier; Rodríguez Fonollosa, José Adrián; Zvonar, Z; Vidal Manzano, José (Institute of Electrical and Electronics Engineers (IEEE), 1995)
    Text en actes de congrés
    Accés obert
    Multiuser detection in code division multiple access systems usually requires either knowledge of the transmitted signature sequences and channel state information or use of a known training sequence for adaptation. We ...
  • New hos-based parameter estimation methods for speech recognition in noisy environments 

    Moreno Bilbao, M. Asunción; Tortola, S; Vidal Manzano, José; Rodríguez Fonollosa, José Adrián (. S.N., 1995)
    Text en actes de congrés
    Accés obert
    The problem of recognition in noisy environments is addressed. Often, a recognition system is used in a noisy environment and there is no possibility of training it with noisy samples. Classical speech analysis techniques ...
  • Adaptive blind equalization using weighted cumulant slices 

    Vidal Manzano, José; Rodríguez Fonollosa, José Adrián (Institute of Electrical and Electronics Engineers (IEEE), 1994)
    Text en actes de congrés
    Accés obert
    Many linear methods have been proposed in the literature to blindly estimate the ARMA parameters of a time series using HOS. Nevertheless, they are mainly off-line and not much has been done in the adaptive case. The method ...
  • Selection of correction candidates for the normalization of Spanish user generated content 

    Melero, Maite; Ruiz Costa-Jussà, Marta; Lambert, Patrik; Quixal, Martí (2016-01-01)
    Article
    Accés obert
    We present research aiming to build tools for the normalization of User-Generated Content (UGC). We argue that processing this type of text requires the revisiting of the initial steps of Natural Language Processing, since ...
  • Estimation of the modulation index of cpm signals using hos 

    Rodríguez Fonollosa, Javier; Rodríguez Fonollosa, José Adrián (Institute of Electrical and Electronics Engineers (IEEE), 1993)
    Text en actes de congrés
    Accés obert
    Three simple methods are proposed for the estimation of the modulation index of continuous phase modulated signals in noise. These methods employ the estimated autocorrelation and fourth-order cumulant sequences of the ...
  • Performance evaluation of interference cancellation techniques using adaptive antennas 

    Antón Haro, Carles; Rodríguez Fonollosa, José Adrián; Rodríguez Fonollosa, Javier (IEEE Vehicular Technology Society, 1998)
    Text en actes de congrés
    Accés obert
    Two array-based algorithms, which jointly exploit or compensate for the spatial and temporal characteristics of the propagation channel, are proposed for intercell interference suppression in UMTS scenarios. The first one ...
  • Assessment of the effect of the financial crisis on agents’ expectations through symbolic regression 

    Claveria, Oscar; Monte Moreno, Enrique; Torra Porras, Salvador (2016-12-16)
    Article
    Accés restringit per política de l'editorial
    Agents’ perceptions on the state of the economy can be affected during economic crises. Tendency surveys are the main source of agents’ expectations. The main objective of this study is to assess the impact of the 2008 ...
