  • Navarrete Terrassa, Antonio, 1973-; Santos Rodríguez, Patrícia; Hernández Leo, Davinia; Blat, Josep (International Forum of Educational Technology & Society, 2011)
    Test-based e-Assessment approaches are mostly focused on the assessment of knowledge and not on that of other skills, which could be supported by multimedia interactive services. This paper presents the QTIMaps model, ...
  • Calabria, Marco; Hernández Pardo, Mireia; Branzi, Francesca Martina, 1984-; Costa, Albert, 1970- (Frontiers, 2012)
    Previous research has shown that highly proficient bilinguals have comparable switch costs in both directions when they switch between languages (L1 and L2), the so-called "symmetrical switch cost" effect. Interestingly, ...
  • Bogdanov, Dmitry; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2017)
    While a vast amount of editorial metadata is being actively gathered and used by music collectors and enthusiasts, it is often neglected by music information retrieval and musicology researchers. In this paper we propose ...
  • Girardin, Fabien; Vaccari, Andrea; Gerber, Alexander; Biderman, Assaf; Ratti, Carlo (Joint Research Centre of the European Commission, 2009)
    In the past, sensors networks in cities have been limited to fixed sensors, embedded in particular locations, under centralised control. Today, new applications can leverage wireless devices and use them as sensors to ...
  • Soto-Iglesias, David; Duchateau, Nicolas Guillem; Butakoff, Constantine; Andreu Martínez, David; Fernández-Armenta, Juan; Bijnens, Bart; Berruezo Sánchez, Antonio; Sitges, Marta; Camara, Oscar (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Electro-anatomical maps (EAMs) are commonly acquired in clinical routine for guiding ablation therapies. They provide voltage and activation time information on a 3-D anatomical mesh representation, making them useful for ...
  • Caro Repetto, Rafael; Zhang, Shuo; Serra, Xavier (2017)
    When lyrics of tonal languages are set to music, the pitch contour of the tones has to agree to a certain extent with the melodic contour to assure intelligibility. The relationship between the linguistic tones of the ...
  • Gialampoukidis, Ilias; Liparas, Dimitris; Vrochidis, Stefanos; Kompatsiaris, Ioannis (CEUR Workshop Proceedings, 2016)
    In this paper, we present a framework for topic detection in news articles. The framework receives as input the results retrieved from a query-based search and clusters them by topic. To this end, the recently introduced ...
  • Santos Rodríguez, Patrícia; Pérez Sanagustín, Maria del Mar; Hernández Leo, Davinia; Blat, Josep (Elsevier, 2011)
    Test-based assessment tools are mostly focused on the use of computers. However, advanced Information and Communication Technologies, such as handheld devices, opens up the possibilities of creating new assessment scenarios, ...
  • Meditskos, Georgios; Dasiopoulou, Stamatia; Vrochidis, Stefanos; Kompatsiaris, Ioannis (ACM Association for Computer Machinery, 2016)
    In this paper we present an ontology-driven framework for natural language question analysis and answering over user models (e.g. preferences, habits and health problems of individuals) that are formally captured using ...
  • Purohit, Hemant; Castillo, Carlos; Imran, Muhammad; Pandey, Rahul (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    xtensive research on social media usage during emergencies has shown its value to provide life-saving information, if a mechanism is in place to filter and prioritize messages. Existing ranking systems can provide a ...
  • Koduri, Gopala Krishna; Gulati, Sankalp; Rao, Preeti; Serra, Xavier; Serra, Xavier (Taylor & Francis (Routledge), 2012)
    Rāga forms the melodic framework for most of the music of the Indian subcontinent. Thus automatic rāga recognition is a fundamental step in the computational modeling of the Indian art-music traditions. In this work, ...
  • Guger, Christoph; Gener, Thomas; Pennartz, Cyriel; Brotons-Mas, Jorge; Edlinger, Günter; Bermúdez i Badia, S.; Verschure, Paul F. M. J.; Schaffelhofer, Stefan; Sanchez-Vives, Maria V (Frontiers Media, 2011)
    Brain–computer interfaces (BCI) are using the electroencephalogram, the electrocorticogram and trains of action potentials as inputs to analyze brain activity for communication purposes and/or the control of external ...
  • Sadat Schaffai, Jasmin, 1982-; Martin, Clara D.; Costa, Albert, 1970-; Alario, F.-Xavier (François -Xavier) (Elsevier, 2014)
    A crucial step for understanding how lexical knowledge is represented is to describe the relative similarity of lexical items, and how it influences language processing. Previous studies of the effects of form similarity ...
  • Amiri, A.; Borda Fortuny, Cristina; Tong, Kin-Fai (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Two different reconfigurable techniques for spectrum-monitoring antenna are presented. The first method inserts high-performance RF-MEMS switches along the microstrip feed line and back slot of a Vivaldi antenna ...
  • Dyer, Chris; Kuncoro, Adhiguna; Ballesteros, Miguel; Smith, Noah A. (ACL (Association for Computational Linguistics), 2016)
    We introduce recurrent neural network grammars,/nprobabilistic models of sentences with/nexplicit phrase structure. We explain efficient/ninference procedures that allow application to/nboth parsing and language modeling. ...
  • Pragst, Louisa; Ultes, Stefan; Minker, Wolfgang (Springer, 2016)
    Getting a good estimation of the Interaction Quality (IQ) of a spoken dialogue helps to increase the user satisfaction as the dialogue strategy may be adapted accordingly. Therefore, some research has already been ...
  • Ledberg, Anders; Montagnini, Anna; Coppola, Richard; Bressler, Sreven L. (Public Library of Science, 2012)
    Sensory responses of the brain are known to be highly variable, but the origin and functional relevance of this variability/nhave long remained enigmatic. Using the variable foreperiod of a visual discrimination task to ...
  • González-Suárez, Ana; Herranz, David; Berjano, Enrique J.; Rubio-Guivernau, Jose L.; Margallo-Balbás, Eduardo (Wiley, 2018)
