  • Bogdanov, Dmitry; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2017)
    While a vast amount of editorial metadata is being actively gathered and used by music collectors and enthusiasts, it is often neglected by music information retrieval and musicology researchers. In this paper we propose ...
  • Caro Repetto, Rafael; Zhang, Shuo; Serra, Xavier (2017)
    When lyrics of tonal languages are set to music, the pitch contour of the tones has to agree to a certain extent with the melodic contour to assure intelligibility. The relationship between the linguistic tones of the ...
  • Gialampoukidis, Ilias; Liparas, Dimitris; Vrochidis, Stefanos; Kompatsiaris, Ioannis (CEUR Workshop Proceedings, 2016)
    In this paper, we present a framework for topic detection in news articles. The framework receives as input the results retrieved from a query-based search and clusters them by topic. To this end, the recently introduced ...
  • Meditskos, Georgios; Dasiopoulou, Stamatia; Vrochidis, Stefanos; Kompatsiaris, Ioannis (ACM Association for Computer Machinery, 2016)
    In this paper we present an ontology-driven framework for natural language question analysis and answering over user models (e.g. preferences, habits and health problems of individuals) that are formally captured using ...
  • Dyer, Chris; Kuncoro, Adhiguna; Ballesteros, Miguel; Smith, Noah A. (ACL (Association for Computational Linguistics), 2016)
    We introduce recurrent neural network grammars,/nprobabilistic models of sentences with/nexplicit phrase structure. We explain efficient/ninference procedures that allow application to/nboth parsing and language modeling. ...
  • Mayor, Oscar; Llimona, Quim; Marchini, Marco, 1984-; Papiotis, Panagiotis, 1985-; Maestre Gómez, Esteban (ACM Association for Computer Machinery, 2013)
    In this technical demo we present repoVizz (http://repovizz.upf.edu), an integrated online system capable of structural formatting and remote storage, browsing, exchange, annotation, and visualization of synchronous ...
  • Mayor, Oscar; Llop, Jordi; Maestre Gómez, Esteban (International Society for Music Information Retrieval (ISMIR), 2011)
    RepoVizz is a data repository and visualization tool for/nstructured storage and user-friendly browsing of music performance/nmulti-modal recordings. The primary purpose of/nRepoVizz is to offer means for the scientific ...
  • Gialampoukidis, Ilias; Moumtzidou, Anastasia; Tsikrika, Theodora; Vrochidis, Stefanos; Kompatsiaris, Ioannis (ACM Association for Computer Machinery, 2016)
    Searching for multimedia objects with heterogeneous modal- ities is critical for the construction of e ective multimedia retrieval systems. Towards this direction, we propose a framework for the multimodal fusion of visual ...
  • Gómez Marín, Daniel; Jordà Puig, Sergi; Herrera Boyer, Perfecto (International Workshop on Musical Metacreation, 2016)
    We present and discuss our view on rhythm spaces, as metaphors to visualize and interact with rhythms. We take advantage on existing research on alternative lowdimensional music spaces, music cognition, music interaction ...
  • Farrús, Mireia; Wagner, Michael; Anguita, Jan; Hernando, Javier (International Speech Communication Association (ISCA), 2008)
    Prosody plays an important role in the human recognition process; therefore, prosodic elements are normally used by impersonators aiming to resemble someone else. Since such voice imitation is one of the potential threats ...
  • Arcos, Josep Lluís; López de Mántaras, Ramon; Serra, Xavier (International Computer Music Conference, 1997)
    We have studied the problem of generating expressive musical performances in the context of tenor saxophone interpretations. We have done several recordings of a tenor sax playing dierent Jazz ballads with dierent degrees ...
  • Sentürk, Sertan; Gulati, Sankalp; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2013)
    Tonic is a fundamental concept in many music traditions/nand its automatic identification should be relevant for establishing/nthe reference pitch when we analyse the melodic/ncontent of the music. In this paper, we present ...
  • Anguera Miró, Xavier, 1978-; Farrús, Mireia; Hernando, Javier (2004)
    L'evolució de la societat de la informació ha esdevingut un incessant increment de continguts audiovisuals que s’emeten constantment en cadenes de televisió i emissores de radio locals i nacionals en llengua catalana. ...
  • Castellví, Quim; Sánchez-Velázquez, Joan; Berjano, Enrique J.; Burdío Pinilla, Fernando; Ivorra Cano, Antoni, 1974- (Springer, 2015)
    Spread tumors in liver are not suitable to be treated with local treatments, such as conventional surgery or radiofrequency ablation, thus entailing a poor prognosis. Electroporation-based therapies imply the delivery of ...
  • Sá Pinto, António; Davies, Matthew E. P.; Herrera Boyer, Perfecto (Universidade de Aveiro, 2016)
    In this paper we present a methodology for converting semantic descriptions of sounds into computable audio features. This process aims to enable the use of commonly used notions of timbre in an audio engineering context ...
  • Rodríguez Fernández, Sara; Espinosa-Anke, Luis; Carlini, Roberto; Wanner, Leo (ACL (Association for Computational Linguistics), 2016)
    L2 learners often produce “ungrammatical” word combinations such as, e.g., *give a suggestion or *make a walk. This is because of the “collocationality” of one of their items (the base) that limits the acceptance of ...
  • Agirre, Eneko; Banea, Carmen; Cer, Daniel; Diab, Mona; Gonzalez Agirre, Aitor; Mihalcea, Rada; Rigau Claramunt, German; Wiebe, Janyce (ACL (Association for Computational Linguistics), 2016)
    Semantic Textual Similarity (STS) seeks to measure the degree of semantic equivalence between two snippets of text. Similarity is expressed on an ordinal scale that spans from semantic equivalence to complete ...
  • Agirre, Eneko; Gonzalez Agirre, Aitor; Lopez-Gazpio, Iñigo; Maritxalar, Montserrat; Rigau Claramunt, German; Uria, Larraitz (ACL (Association for Computational Linguistics), 2016)
    The final goal of Interpretable Semantic Textual Similarity (iSTS) is to build systems that explain which are the differences and commonalities between two sentences. The task adds an explanatory level on top of STS, ...
  • Angelosante, Daniele; Biglieri, Ezio; Lops, Marco (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    In this paper, we introduce a pilot-aided multipath channel estimator for Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) systems. Typical estimation algorithms assume the number of ...
  • Rullo, Antonino; Serra, Edoardo; Bertino, Elisa; Lobo, Jorge (Springer, 2017)
    We present a method for computing the best provisioning of security resources for Internet of Things (IoT) scenarios characterized by a high degree of mobility. The security infrastructure is specifed by a security ...
