  • Sordo, Mohamed; Serrà Julià, Joan; Koduri, Gopala Krishna; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    In this paper a method for extracting semantic information from online music discussion forums is proposed. The semantic relations are inferred from the co-occurrence of musical concepts in forum posts, using network ...
  • Serrà Julià, Joan; Koduri, Gopala Krishna; Miron, Marius; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2011)
    The issue of tuning in Indian classical music has been, historically, a matter of theoretical debate. In this paper, we study its contemporary practice in sung performances of Carnatic and Hindustani music following an ...
  • Koduri, Gopala Krishna; Serrà Julià, Joan; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2012)
    Intonation is an important concept in Carnatic music that is characteristic of a raaga, and intrinsic to the musical expression of a performer. In this paper we approach the description of intonation from a computational ...
  • Koduri, Gopala Krishna; Serrà Julià, Joan; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    Intonation is a fundamental music concept that has a special relevance in Indian art music. It is characteristic of the rāga and intrinsic to the musical expression of the performer. Describing intonation is of importance ...
  • Serrà Julià, Joan; Gómez Gutiérrez, Emilia; Herrera Boyer, Perfecto; 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 ...
  • Koduri, Gopala Krishna; Miron, Marius; Serrà Julià, Joan; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2011)
    The classical music traditions of the Indian subcontinent, Hindustani and Carnatic, offer an excellent ground on which to test the limitations of current music information research approaches. At the same time, studies ...
  • 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 ...
  • Sordo, Mohamed; Serrà Julià, Joan; Koduri, Gopala Krishna; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2012)
    By mining user-generated text content we can obtain musicrelated information that could not otherwise be extracted from audio signals or symbolic score representations. In this paper we propose a methodology for ...
  • Font, Frederic; Serrà Julià, Joan; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2012)
    Collaborative tagging has emerged as an efficient way to semantically describe online resources shared by a community of users. However, tag descriptions present some drawbacks such as tag scarcity or concept ...
  • 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. ...
