  • Bantula, Helena; Giraldo, Sergio Iván; Ramírez, Rafael,1966- (International Society for Music Information Retrieval (ISMIR), 2016)
    Computational expressive music performance studies the analysis and characterisation of the deviations that a musician introduces when performing a musical piece. It has been studied in a classical context where timing ...
  • Farrús, Mireia (International Speech Communication Association (ISCA), 2007)
    Jitter and shimmer are measures of the cycle-to-cycle variations of fundamental frequency and amplitude, respectively, which have been largely used for the description of pathological voice quality. Since they characterise ...
  • Palomares, Roberto P.; Haro Ortega, Gloria; Ballester, Coloma (SCITEPRESS – Science and Technology Publications, Lda., 2017)
    This paper presents a novel variational approach for the joint estimation of scene flow and occlusions. Our method does not assume that a depth sensor is available. Instead, we use a stereo sequence and exploit the fact ...
  • Prieto, Luis P.; Martínez-Maldonado, Roberto; Spikol, Daniel; Hernández Leo, Davinia; Rodríguez-Triana, María Jesús; Ochoa, Xavier (CEUR Workshop Proceedings, 2017)
    Learning is a complex, mostly invisible process that happens across spaces, occurring in the physical world but also increasingly in virtual worlds or web-based spaces. In order to explore what happens in such blended ...
  • Faraldo Pérez, Ángel; Gómez Gutiérrez, Emilia, 1975-; Jordà Puig, Sergi; Herrera Boyer, Perfecto (Springer, 2016)
    In this paper we study key estimation in electronic dance music, an umbrella term referring to a variety of electronic music subgenres intended for dancing at nightclubs and raves. We start by defining notions of tonality ...
  • Delli Bovi, Claudio; Espinosa-Anke, Luis; Navigli, Roberto (ACL (Association for Computational Linguistics), 2015)
    We present KB-UNIFY, a novel approach for integrating the output of different Open Information Extraction systems into a single unified and fully disambiguated knowledge repository. KB-UNIFY consists of three main steps: ...
  • Ronzano, Francesco; Saggion, Horacio (Springer, 2016)
    During the last decade the amount of scientific articles available online has substantially grown in parallel with the adoption of the Open Access publishing model. Nowadays researchers, as well as any other interested ...
  • Dafa, Lehdia Mohamed; Baudracco, Chiara; Moragas, Ana; Llor Vila, Carles; Molero Trujillo, David; Vilanova Estrada, Pere (Sociedad Española de Medicina de Familia y Comunitaria, 2017)
    Las tecnologías de la información y comunicación (TIC) están posibilitando grandes beneficios en el campo de la salud. En este sentido, KRISTINA (Knowledge-Based Information Agent with Social Competence and Human Interaction ...
  • Wanner, Leo; André, Elisabeth; Blat, Josep; Dasiopoulou, Stamatia; Farrús, Mireia; Kamateri, Eleni; Lingenfelser, Florian; Llorach, Gerard; Martínez, Oriol; Meditskose, Georgios; Mille, Simon; Minker, Wolfgang; Pragst, Louisa; Schiller, Dominik; Stam, Andries; Stellingwerff, Ludo; Sukno, Federico Mateo; Vieru, Bianca; Vrochidis, Stefanos (Springer, 2017)
    We present an intelligent embodied conversation agent with linguistic, social and emotional competence. Unlike the vast majority of the state-of-the-art conversation agents, the proposed agent is constructed around an ...
  • Oliver, Maria; Haro Ortega, Gloria; Fedorov, Vadim; Ballester, Coloma (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    This paper proposes a novel patch-based variational segmentation method that considers adaptive patches to characterize, in an affine invariant way, the local structure of each homogeneous texture region of the image and ...
  • Gulati, Sankalp; Serrà Julià, Joan; Ganguli, Kaustuv Kanti; Serra, Xavier (2014)
    Musical melodies contain hierarchically organized events, where some events are more salient than others, acting as melodic landmarks. In Hindustani music melodies, an important landmark is the occurrence of a nyas. ...
  • Calabria, Marco; Cattaneo, Gabriele, 1984-; Marne, Paula; Hernández Pardo, Mireia; Juncadella, Montserrat; Gascón-Bayarri, Jordi; Sala, Isabel; Lleó, Alberto; Ortiz-Gil, Jordi; Ugas, Lidia; Blesa, Rafael; Reñé, Ramón; Costa, Albert, 1970- (Elsevier, 2017)
    In the context of bilingual research, little is known about the effects of neurodegenerative disorders (NDs) on the processing of two languages in a bilingual. In a recent cross-sectional study, we showed that Mild Cognitive ...
  • Biglieri, Ezio; Grossi, Emanuele; Lops, Marco; Tauste Campo, Adrià (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    We study the minimum mean square error (MMSE) and the multiuser efficiency η of large dynamic multiple access communication systems in which optimal multiuser detection is performed at the receiver as the number and the ...
  • AbuRa’ed, Ahmed; Chiruzzo, Luis; Saggion, Horacio; Accuosto, Pablo; Bravo Serrano, Àlex, 1984- (2017)
    In recent years there has been an increasing interest in approaches to scienti c summarization that take advantage of the citations a research paper has received in order to extract its main contributions. In this ...
  • AbuRa’ed, Ahmed; Saggion, Horacio (ACL (Association for Computational Linguistics), 2018)
    This paper presents the participation of the LaSTUS/TALN team in the Complex Word Identification (CWI) Shared Task 2018 in the English monolingual track . The purpose of the task was to determine if a word in a ...
  • AbuRa’ed, Ahmed; Bravo Serrano, Àlex, 1984-; Chiruzzo, Luis; Saggion, Horacio (CEUR Workshop Proceedings, 2018)
    In this paper we present several systems developed to partic- ipate in the 3rd Computational Linguistics Scienti c Document Summa- rization Shared challenge which addresses the problem of summarizing a scienti c paper ...
  • Michos, Konstantinos; Fernández, Arnau; Hernández Leo, Davinia; Calvo, Roman (2017)
    This demonstration paper presents the Ld-Feedback mobile applica-tion. A variety of learning design tools were developed during the last years. However, there is still lack of substantial understanding on how learning ...
  • Hernández Leo, Davinia; Moreno, Pau; Chacón Pérez, Jonathan, 1986-; Blat, Josep (Elsevier, 2014)
    Some educational innovation initiatives require practitioners to team up on the design of new learning activities. However, existing learning design tooling does not integrally support their tasks. Some tools enable authoring ...
