Recent Submissions

  • Wentland, Wolodja; Silberer, Carina; Hartung, Matthias (ELRA (European Language Resources Association), 2008)
    In this paper, we present HeiNER, the multilingual Heidelberg Named Entity Resource. HeiNER contains 1,547,586 disambiguated English Named Entities together with translations and transliterations to 15 languages. Our work ...
  • Silberer, Carina; Ponzetto, Simone Paolo (ACL (Association for Computational Linguistics), 2010)
    We describe the University of Heidelberg (UHD) system for the Cross-LingualWord Sense Disambiguation SemEval-2010 task (CL-WSD). The system performs CLWSD by applying graph algorithms previously developed for monolingual ...
  • Silberer, Carina; Lapata, Mirella (ACL (Association for Computational Linguistics), 2012)
    A popular tradition of studying semantic representation has been driven by the assumption that word meaning can be learned from the linguistic environment, despite ample evidence suggesting that language is grounded in ...
  • Silberer, Carina; Frank, Anette (ACL (Association for Computational Linguistics), 2012)
    Linking implicit semantic roles is a challenging problem in discourse processing. Unlike prior work inspired by SRL, we cast this problem as an anaphora resolution task and embed it in an entity-based coreference ...
  • Silberer, Carina; Ferrari, Vittorio; Lapata, Mirella (ACL (Association for Computational Linguistics), 2013)
    We consider the problem of grounding the meaning of words in the physical world and focus on the visual modality which we represent by visual attributes. We create a new large-scale taxonomy of visual attributes covering ...
  • Stowell, Dan; Muševič, Sašo; Bonada, Jordi, 1973-; Plumbley, Mark D. (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Segregating an audio mixture containing multiple simultaneous bird sounds is a challenging task. However, birdsong often contains rapid pitch modulations, and these modulations carry information which may be of use in ...
  • Smeros, Panayiotis; Castillo, Carlos; Aberer, Karl (ACM Association for Computer Machinery, 2019)
    This paper describes, develops, and validates SciLens, a method to evaluate the quality of scientific news articles. The starting point for our work are structured methodologies that define a series of quality aspects for ...
  • Caro Repetto, Rafael; Serra, Xavier (2016)
    En sus poco más de doscientos años de historia, el jingju, u ópera de Pekín, ha conseguido el título de tesoro nacional (guocui) y como tal ha asumido la turbulenta historia reciente del país. En la puja por situarse como ...
  • Puiggròs, Montserrat; Gómez Gutiérrez, Emilia, 1975-; Ramírez, Rafael,1966-; Serra, Xavier; Bresin, Roberto (Bononia University Press, 2006)
    Expressive performance characterization is traditionally based on the analysis of the main differences between performances, players, playing styles and emotional intentions. This work addresses the characterization of ...
  • Caro Repetto, Rafael; Serra, Xavier (2016)
    Music in jingju (also known as Peking or Beijing opera) is predefined by tradition. Before the appearance of jingju music composers, actors used to “arrange melodies” (bianqu) for new lyrics according to melodic systems ...
  • Demirel, Emir; Bozkurt, Baris; Serra, Xavier (Sound & Music Computing Conference, 2019)
    This study focuses on the application of different computational methods to carry out a ”modal harmonic analysis” for Jazz improvisation performances by modeling the concept of chord-scales. The Chord-Scale Theory is a ...
  • Nistal, Javier; Herrera Boyer, Perfecto; Jordà Puig, Sergi (2017)
    We present a study on the behavior of human finger-tapping and the spontaneous expression of rhythm. For the purposes of this study we construe interpret finger-tapping as the casual and rhythmic hitting of objects for ...
  • Faraldo Pérez, Ángel; Herrera Boyer, Perfecto (2017)
    In this paper we present an interactive two-dimensional representation of musical chord progressions, integrated into a computer program that generates house music harmonic loops in MIDI format, based on a user’s input. ...
  • Dalmazzo, David; Ramírez, Rafael,1966- (ACM Association for Computer Machinery, 2017)
    We train and evaluate two machine learning models for predicting fingering in violin performances using motion and EMG sensors integrated in the Myo device. Our aim is twofold: first, provide a fingering recognition model ...
  • Batard, Thomas; Bertalmío, Marcelo (Springer, 2013)
    We introduce a gradient operator that generalizes the Eu- clidean and Riemannian gradients. This operator acts on sections of vector bundles and is determined by three geometric data: a Rieman- nian metric on the base ...
  • Galdran, Adrian; Vazquez-Corral, Javier; Pardo, David; Bertalmío, Marcelo (Springer, 2015)
    Images captured under adverse weather conditions, such as haze or fog, typically exhibit low contrast and faded colors, which may severely limit the visibility within the scene. Unveiling the image struc- ture under the ...
  • Cyriac, Praveen; Batard, Thomas; Bertalmío, Marcelo (Springer, 2014)
    Given any metric that compares images of di erent dynamic range, we propose a method to reduce their distance with respect to this metric. The key idea is to consider the metric as a non local operator. Then, we transform ...
  • Batard, Thomas (Springer, 2014)
    We present a method to perform histogram matching be- tween two color images based on the concept of harmonic mapping be- tween Riemannian manifolds. The key idea is to associate the histogram of a color image to a ...
  • Ghimpeteanu, Gabriela; Batard, Thomas; Bertalmío, Marcelo; Levine, Stacey (Springer, 2014)
    In this paper, we provide a new non-local method for image denoising. The key idea we develop is to denoise the components of the image in a well-chosen moving frame instead of the image itself.We prove the relevance ...
  • Kolobov, Andrey; Mausam; Weld, Daniel S.; Geffner, Héctor (Association for the Advancement of Artificial Intelligence (AAAI), 2011)
    Research in efficient methods for solving infinite-horizon MDPs has so far concentrated primarily on discounted MDPs and the more general stochastic shortest path problems (SSPs). These are MDPs with 1) an optimal value ...
