  • Urbano, Julián (Music Information Retrieval Evaluation eXchange (MIREX), 2014)
    This short paper describes our three submissions to the 2014 edition of the MIREX Symbolic Melodic Similarity task. All three submissions rely on a geometric model that represents melodies as spline curves in the pitch-time ...
  • Urbano, Julián (Music Information Retrieval Evaluation eXchange (MIREX), 2015)
    This short paper describes our three submissions to the 2015 edition of the MIREX Symbolic Melodic Similarity task. They all rely on a geometric model that represents melodies as spline curves in the pitch-time plane. The ...
  • Holzapfel, Andre; Bozkurt, Baris (Universitat Pompeu Fabra, 2012)
    In this paper we investigate how note onsets in Turkish Makam music compositions are distributed, and in how far this distribution supports or contradicts the metrical structure of the pieces, the usul. We use MIDI data ...
  • Amatriain, Xavier; Bonada, Jordi, 1973-; Serra, Xavier (International Conference on Digital Audio Effects, 1998)
    Since the MIDI 1.0 specification, well over 15 years ago, many have been the attempts to give a solution to all the limitations that soon became clear. None of these have had a happy ending, mainly due to commercial ...
  • Porter, Alastair; Bogdanov, Dmitry; Serra, Xavier (ACM Association for Computer Machinery, 2016)
    Semantic annotations of music collections in digital libraries are important for organization and navigation of the collection. These annotations and their associated metadata are useful in many Music Information Retrieval ...
  • Urbano, Julián (Music Information Retrieval Evaluation eXchange (MIREX), 2013)
    This short paper describes our three submissions to the 2013 edition of the MIREX Symbolic Melodic Similarity task. All three submissions rely on a geometric model that represents melodies as spline curves in the pitch-time ...
  • Anantapadmanabhan, Akshay; Bellur, Ashwin; Murthy, Hema A. (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    In this paper we use a Non-negative Matrix Factorization/n(NMF) based approach to analyze the strokes of the mri-/ndangam, a South Indian hand drum, in terms of the normal/nmodes of the instrument. Using ...
  • Blaauw, Merlijn; Bonada, Jordi, 1973- (International Speech Communication Association (ISCA), 2016)
    Latent generative models can learn higher-level underlying factors from complex data in an unsupervised manner. Such models can be used in a wide range of speech processing applications, including synthesis, transformation ...
  • Dzhambazov, Georgi Bogomilov; Serra, Xavier (Music Technology Research Group, Department of Computer Science, Maynooth University, 2015)
    In this work we propose how to modify a standard scheme for text-to-speech alignment for the alignment of lyrics and singing voice. To this end we model the duration of phonemes specific for the case of singing. We rely ...
  • Miron, Marius; Janer Mestres, Jordi; Gómez Gutiérrez, Emilia, 1975- (International Society for Music Information Retrieval (ISMIR), 2017)
    Score information has been shown to improve music source separation when included into non-negative matrix factorization (NMF) frameworks. Recently, deep learning approaches have outperformed NMF methods in terms ...
  • Chandna, Pritish; Miron, Marius; Janer Mestres, Jordi; Gómez Gutiérrez, Emilia, 1975- (Springer, 2017)
    In this paper we introduce a low-latency monaural source separation framework using a Convolutional Neural Network (CNN). We use a CNN to estimate time-frequency soft masks which are applied for source separation. We ...
  • Bellur, Ashwin; Ishwar, Vignesh; Murthy, Hema A. (Universitat Pompeu Fabra, 2012)
    A raga is a collective melodic expression consisting of motifs. A raga can be identified using motifs which are/nunique to it. Motifs can be thought of as signature prosodic phrases. Different ragas may be composed of the ...
  • Ruiz Ovejero, Adrià; Rudovic, Ognjen; Binefa i Valls, Xavier; Pantic, Maja (Springer, 2017)
    In this paper, we address the Multi-Instance-Learning (MIL) problem when bag labels are naturally represented as ordinal variables (Multi-Instance-Ordinal Regression). Moreover, we consider the case where bags are temporal ...
  • Oramas, Sergio; Nieto Caballero, Oriol; Barbieri, Francesco; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2017)
    Music genres allow to categorize musical items that share common characteristics. Although these categories are not mutually exclusive, most related research is traditionally focused on classifying tracks into a single ...
  • Accuosto, Pablo; Ronzano, Francesco; Ferrés, Daniel; Saggion, Horacio (2017)
    We present a system to mine and visualize collections of scientific documents by semantically browsing information extracted from single publications or aggregated throughout corpora of articles. The text mining tool ...
  • Papiotis, Panos; Marchini, Marco, 1984-; Maestre Gómez, Esteban (Associoation Européenne des Conservatoires, 2013)
    In a musical ensemble such as a string quartet, the performers can influence each other’s actions in several aspects of the performance simultaneously. Based on a set of recorded string quartet exercises, we carried out a ...
  • Perez Miguel, Naiara; Cuadros Oller, Montse (ACL (Association for Computational Linguistics), 2017)
    This paper describes a web-based application to design and answer exercises for language learning. It is available in Basque, Spanish, English, and French. Based on open-source Natural Language Processing (NLP) ...
  • Agerri, Rodrigo; Aldabe, Itziar; Laparra, Egoitz; Rigau Claramunt, German; Fokkens, Antske; Huijgen, Paul; Izquierdo Beviá, Rubén; van Erp, Marieke; Vossen, Piek; Minard, Anne-Lyse; Magnini, Bernardo (International Conference on Language Resources and Evaluation (LREC), 2016)
    We describe a novel modular system for cross-lingual event extraction for English, Spanish,, Dutch and Italian texts. The system consists of a ready-to-use modular set of advanced multilingual Natural Language Processing ...
  • Farrús, Mireia; Luque, Jordi; Morros, R.; Anguita, Jan; Macho, D.; Marqués, M.; Martínez, C.; Vilaplana, V.; Hernando, Javier (Universidad de Zaragoza, 2006)
