    The emergence of the Web 2.0 technologies in the last years have/nchanged the way people interact with knowledge. Services for cooperation and/ncollaboration have placed the user in the centre of a new knowledge building/nspace. ...
  • Sikora, Martin, 1976-; Laayouni, Hafid, 1968-; Calafell i Majó, Francesc; Comas, David, 1969-; Bertranpetit, Jaume, 1952- (Nature Publishing Group, 2011)
    Studies of large sets of SNP data have proven to be a powerful tool in the analysis of the genetic structure of human populations. In this work, we analyze genotyping data for 2,841 SNPs in 12 Sub-Saharan African populations, ...
  • Bellur, Ashwin; Ishwar, Vignesh; Serra, Xavier; Murthy, Hema A. (Universitat Pompeu Fabra, 2012)
    In this paper, we describe several techniques for detecting tonic pitch value in Indian classical music. In Indian music, the raga is the basic melodic framework and it is built on the tonic. Tonic detection is therefore ...
  • Sordo, Mohamed; Serrà Julià, Joan; Koduri, Gopala Krishna; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    In this paper a method for extracting semantic information/nfrom online music discussion forums is proposed. The semantic relations are inferred from the co-occurrence of musical concepts in forum posts, using network ...
  • Sordo, Mohamed; Koduri, Gopala Krishna; Sentürk, Sertan; Gulati, Sankalp; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    In the context of the CompMusic project we are developing methods to automatically describe/annotate audio music recordings pertaining to various music cultures. As a/nway to demonstrate the usefulness of the methods we ...
  • Cunha Fanego, Iria da; Fernández, Silvia; Velázquez Morales, Patricia; Vivaldi, J. (Jorge), 1952-; SanJuan, Eric; Torres Moreno, Juan Manuel (Springer, 2007)
    In this article we present a hybrid approach for automatic summarization of Spanish medical texts. There are a lot of systems for automatic summarization using statistics or linguistics, but only a few of them combining ...
  • Morales del Castillo, José Manuel, 1974-; Pedraza, Rafael; Ruiz Rodríguez, Antonio Ángel; Peis, Eduardo; Herrera-Viedma, Enrique (ALA American Library Association, 2010)
    In this paper we present the theoretical and methodological/nfoundations for the development of a multi-agent/nSelective Dissemination of Information (SDI) service/nmodel that applies Semantic Web technologies for ...
  • Takeuchi, Akiko; Schmitt, David; Chapple, Charles E.; Babaylova, Elena; Karpova, Galina; Guigó Serra, Roderic; Krol, Alain; Allmang, Christine (Oxford University Press, 2009)
    Selenoproteins contain the amino acid selenocysteine which is encoded by a UGA Sec codon. Recoding UGA Sec requires a complex mechanism, comprising the cis-acting SECIS RNA hairpin in the 3′UTR of selenoprotein mRNAs, and ...
  • Wang, Ni-Chun; Biglieri, Ezio; Yao, Kung (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    A systolic array to implement lattice-reduction-aided linear/ndetection is proposed for a MIMO receiver. The lattice reduction/nalgorithm and the ensuing linear detections are operated in the same array, which can be ...
  • Gulati, Sankalp; Salamon, Justin; Serra, Xavier (Universitat Pompeu Fabra, 2012)
    In this paper we propose a new approach for tonic identification in Indian art music and present a proposal for a/ncomplete iterative system for the same. Our method splits the task of tonic pitch identification into two ...
  • Jindal, Nihar; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    The optimization of the pilot overhead in single-user wireless fading channels is investigated, and the dependence of this overhead on various system parameters of interest (e.g., fading rate, signal-to-noise ratio) is ...
