      Article
      Accés obert
      This work describes the development of a social chatbot for the football domain. The chatbot, named chatbol, aims at answering a wide variety of questions related to the Spanish football league “La Liga”. Chatbol is deployed ...

    • Experimental research on encoder-decoder architectures with attention for chatbots 

      Ruiz Costa-Jussà, Marta; Nuez, Álvaro; Segura, Carlos (2018-03-18)
      Article
      Accés restringit per política de l'editorial
      Chatbots aim at automatically offering a conversation be- tween a human and a computer. While there is a long track of re- search in rule-based and retrieval-based approaches, the generation-based approaches are promisingly ...

    • GCC-PHAT based head orientation estimation 

      Segura, Carlos; Hernando Pericás, Francisco Javier (2012)
      Text en actes de congrés
      Accés obert
      This work presents a novel two-step algorithm to estimate the orientation of speakers in a smart-room environment equipped with microphone arrays. First the position of the speaker is estimated by the SRP-PHAT algorithm, ...

    • El Método científico en la era de los ordenadores
