  • Espinosa-Anke, Luis; Saggion, Horacio; Ronzano, Francesco (ACL (Association for Computational Linguistics), 2015)
    This paper describes the system submitted by the TALN-UPF team to SEMEVAL Task 17 (Taxonomy Extraction Evaluation). We present a method for automatically learning a taxonomy from a flat terminology, which benefits from a ...
  • Font Corbera, Frederic; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2016)
    Tempo estimation is a common task within the music information retrieval community, but existing works are rarely evaluated with datasets of music loops and the algorithms are not tailored to this particular type of content. ...
  • Blat, Josep; Ramírez, Rafael,1966-; Hernández Leo, Davinia (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    This paper presents a study designed to understand the effect of using a talking head in academic videos frequently used in video-based learning approaches, such Massive Open Online Courses. The experiment consisted of ...
  • Segers, Roxane; Rospocher, Marco; Vossen, Piek; Laparra, Egoitz; Rigau Claramunt, German; Minard, Anne-Lyse (ELRA (European Language Resources Association), 2016)
    This paper presents the Event and Implied Situation Ontology (ESO), a manually constructed resource which formalizes the pre and post situations of events and the roles of the entities affected by an event. The ontology ...
  • Kane, David; Bertalmío, Marcelo (The Society for Imaging Science and Technology (IS&T), 2016)
    We investigate the role of lightness perception in determining the perceived contrast of images. In particular, it is known that the background luminance of a display affects the relationship between onscreen luminance and ...
  • Domínguez Bajo, Mónica; Farrús, Mireia; Burga Díaz, Alicia; Wanner, Leo (ISCA, 2014)
    Several grammar theories relate information structure and prosody, highlighting a major correspondence between theme and rheme, and intonation patterns. Although these theories have been successfully exploited in some ...
  • Gil Rodríguez, Raquel; Vazquez-Corral, Javier; Bertalmío, Marcelo (The British Machine Vision Association (BMVA), 2015)
    In this paper we present a novel approach to the problem of exposure fusion of a stack of pictures for the generation of high dynamic range (HDR) radiance maps. All exposure fusion approaches, when applied on 8-bit non-RAW ...
  • Urbano, Julián; Bogdanov, Dmitry; Porter, Alastair; Urbano, Julián; Schreiber, Hendrik (2017)
    This paper provides an overview of the AcousticBrainz Genre Task organized as part of the MediaEval 2017 Benchmarking Initiative for Multimedia Evaluation. The task is focused on content-based music genre recognition ...
  • Resina, Eduard; Serra, Xavier (International Computer Music Conference, 1999)
    The Musicians' Software Mall is a software package developed to provide powerful composition and performance tools to the computer musician. At this stage it contains the following applications: SmsTools 2.0, a set of tools ...
  • Kane, David; Bertalmío, Marcelo (The Society for Imaging Science and Technology (IS&T), 2016)
    We investigate the impact of the background luminance upon the perceived image quality of real world scenes. To do so, we generate a set of small image patches that span the full range of mean luminance values and contrasts ...
  • Hernández Leo, Davinia; Moreno, Verónica (2010-07-22)
    One of the strategies of Universitat Pompeu Fabra to support Quality Learning has been the creation of Units for the Support of Teaching Quality and Innovation within each faculty. In the seminar we will present the role ...
  • Farrús, Mireia; Poch, Marc; Costa-jussà, Marta R.; Mariño Acebal, José B.; Hernández, Adolfo; Henríquez, Carlos; Fonollosa, José A Rodriguez (2009)
    In this paper the statistical machine translator (SMT) between Catalan and Spanish developed at the TALP research center (UPC) and its web demonstration are described.
  • Gulati, Sankalp; Serrà Julià, Joan; Ganguli, Kaustuv Kanti; Sentürk, Sertan; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2016)
    Raga is the melodic framework of Indian art music. It is a core concept used in composition, performance, organization, and pedagogy. Automatic raga recognition is thus a fundamental information retrieval task in Indian ...
  • Marchini, Marco, 1984-; Papiotis, Panagiotis, 1985-; Maestre Gómez, Esteban (University of London, 2012)
    This work presents a preliminary study of timing synchronization/nphenomena in string quartet performance. Accurate timing information/nextracted from real recordings is used to compare timing deviations/nin solo and ...
  • Gialampoukidis, Ilias; Vrochidis, Stefanos; Kompatsiaris, Ioannis; Antoniou, Ioannis (2017)
    Topic detection is usually considered as a decision process implemented in some relevant context, for example clustering. In this case, clusters correspond to topics that should be identifed. Density-based clustering, ...
  • Dalmau, Víctor; Krokhin, Andrei; Manokaran, Rajsekar (SIAM (Society for Industrial and Applied Mathematics), 2015)
    We study the approximability of Minimum Constraint Satisfaction Problems (Min CSPs) with a fixed finite constraint language Γ on an arbitrary finite domain. The goal in such a problem is to minimize the number of unsatisfied ...
  • Wanner, Leo; Blat, Josep; Dasiopoulou, Stamatia; Domínguez Bajo, Mónica; Llorach, Gerard; Mille, Simon; Sukno, Federico Mateo; Kamateri, Eleni; Kompatsiaris, Ioannis; Vrochidis, Stefanos; André, Elisabeth; Lingenfelser, Florian; Mehlmann, Gregor; Stam, Andries; Stellingwerff, Ludo; Lamel, Lori; Vieru, Bianca; Minker, Wolfgang; Pragst, Louisa; Ultes, Stefan (ACM Association for Computer Machinery, 2016)
    We present work in progress on an intelligent embodied conversation agent in the basic care and healthcare domain. In contrast to most of the existing agents, the presented agent is aimed to have linguistic cultural, social ...
  • Becerra-Fajardo, Laura; Ivorra Cano, Antoni, 1974- (Institute of Electrical and Electronics Engineers (IEEE), 2014)
