  • Font Corbera, Frederic; Serrà Julià, Joan; Serra, Xavier (ACM Association for Computer Machinery, 2015)
    Collaborative tagging systems have emerged as a successful solution for annotating contributed resources to online sharing platforms, facilitating searching, browsing, and organizing their contents. To aid users in the ...
  • Serrà Julià, Joan; Zanin, Massimiliano; Herrera Boyer, Perfecto, 1964-; Serra, Xavier (Elsevier, 2012)
    The use of community detection algorithms is explored within the framework of cover song identification, i.e. the automatic detection of different audio renditions of the same underlying musical piece. Until now, this task ...
  • Serrà Julià, Joan; Gómez Gutiérrez, Emilia, 1975-; Herrera Boyer, Perfecto, 1964-; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    We present a new technique for audio signal comparison based on tonal subsequence alignment and its application to detect cover versions (i.e., different performances of the same underlying musical piece). Cover song ...
  • Font Corbera, Frederic; Serrà Julià, Joan; Serra, Xavier (Elsevier, 2014)
    Online sharing platforms often rely on collaborative tagging systems for annotating content. In this way, users themselves annotate and describe the shared contents using textual labels, commonly called tags. These annotations ...
  • Serrà Julià, Joan; Zanin, Massimiliano; Herrera Boyer, Perfecto, 1964- (Interlude, 2011)
    The application of community detection in complex networks is explored within the framework of cover song identification, i.e. the automatic detection of different audio renditions of the same underlying musical piece. In ...
  • Serrà Julià, Joan; Serra, Xavier; Andrzejak, Ralph Gregor (Institute of Physics (IOP), 2009)
    There is growing evidence that nonlinear time series analysis techniques can be used to successfully characterize, classify, or process signals derived from realworld dynamics even though these are not necessarily deterministic ...
  • Font Corbera, Frederic; Serrà Julià, Joan; Serra, Xavier (IGI Global, 2013)
    Collaborative tagging has emerged as a common solution for labelling and organising online digital content. However, collaborative tagging systems typically suffer from a number of issues such as tag scarcity or ambiguous ...
  • Laurier, Cyril François; Meyers, Owen; Serrà Julià, Joan; Blech, Martin; Herrera Boyer, Perfecto, 1964-; Serra, Xavier (Springer, 2010)
    In the context of content analysis for indexing and retrieval, a method for creating automatic music mood annotation is presented. The method is based on results from psychological studies and framed into a supervised ...
  • Koduri, Gopala Krishna; Ishwar, Vignesh; Serrà Julià, Joan; Serra, Xavier (Taylor & Francis (Routledge), 2014)
    Intonation is a fundamental music concept that has a special relevance in Indian art music. It is characteristic of a rga and key to the musical expression of the artist. Describing intonation is of importance to several ...
  • Serrà Julià, Joan; Kantz, Holger; Serra, Xavier; Andrzejak, Ralph Gregor (Institute of Electrical and Electronics Engineers (IEEE), 2011)
    Intuitively, music has both predictable and unpredictable components. In this work we assess this qualitative statement in a quantitative way using common time series models fitted to state-of-the-art music descriptors. ...
  • Serrà Julià, Joan; Gómez Gutiérrez, Emilia, 1975-; Herrera Boyer, Perfecto, 1964-; Serra, Xavier (Taylor & Francis (Routledge), 2008)
    Motivated by evidence that image source statistics predict the response properties of several visual perception aspects, we provide an empirical analysis of the relation between chroma statistics and human judgments of ...
  • Salomon, Justin; Serrà Julià, Joan; Gómez Gutiérrez, Emilia, 1975- (Springer, 2013)
    In this study we compare the use of different music representations for retrieving alternative performances of the same musical piece, a task commonly referred to as version identification. Given the audio signal of a song, ...
  • Bogdanov, Dmitry; Serrà Julià, Joan; Wack, Nicolas; Herrera Boyer, Perfecto, 1964-; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2011)
    Measuring music similarity is essential for multimedia retrieval. For music items, this task can be regarded as obtaining a suitable distance measurement between songs defined on a certain feature space. In this paper, we ...
  • Haro Berois, Martín; Serrà Julià, Joan; Herrera Boyer, Perfecto, 1964-; Corral, Álvaro (Public Library of Science (PLoS), 2012)
    Timbre is a key perceptual feature that allows discrimination between different sounds. Timbral sensations are highly dependent on the temporal evolution of the power spectrum of an audio signal. In order to quantitatively ...
