  • Rankothge, Windhya; Le, Franck; Russo, Alessandra; Lobo, Jorge (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Network Function Virtualization (NFV) is bringing closer the possibility to truly migrate enterprise data centers into the cloud. However, for a Cloud Service Provider to offer such services, important questions include ...
  • Pons Puig, Jordi; Lidy, Thomas; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    A common criticism of deep learning relates to the difficulty in understanding the underlying relationships that/nthe neural networks are learning, thus behaving like a black-box. In this article we explore various ...
  • AbuRa’ed, Ahmed; Chiruzzo, Luis; Saggion, Horacio (ELRA (European Language Resources Association), 2018)
    The identification of explicit and implicit citations to a given reference paper is important for numerous scientific text mining activities such as citation purpose identification, scientific opinion mining, and scientific ...
  • Serra, Xavier (Logos Verlag Berlin, 2013)
    Music Information Research (MIR) is a discipline that aims to understand and model music from an information processing perspective, but the successful approaches used in MIR are going beyond the traditional data processing ...
  • Doulaverakis, Charalampos; Vrochidis, Stefanos; Kompatsiaris, Ioannis (SCITEPRESS, 2015)
    Ontology alignment is the process where two different ontologies that usually describe similar domains are ’aligned’, i.e. a set of correspondences between their entities, regarding semantic equivalence, is determined. In ...
  • Oramas, Sergio; Espinosa-Anke, Luis; Lawlor, Aonghus; Serra, Xavier; Saggion, Horacio (International Society for Music Information Retrieval (ISMIR), 2016)
    In this paper, we explore a large multimodal dataset of about 65k albums constructed from a combination of Amazon customer reviews, MusicBrainz metadata and AcousticBrainz audio descriptors. Review texts are further ...
  • Barbieri, Francesco; Marujo, Luís; Karuturi, Pradeep; Brendel, William; Saggion, Horacio (CEUR Workshop Proceedings, 2018)
    The frequent use of Emojis on social media platforms has created a new form of multimodal social interaction. Developing methods for the study and representation of emoji semantics helps to improve future multimodal ...
  • Pragst, Louisa; Minker, Wolfgang; Ultes, Stefan (© Springer The final publication is available at Springer via https://doi.org/10.1007/978-3-319-92108-2_20, 2017)
    In this paper, we investigate the applicability of soft changes to the system behaviour, namely changing the amount of elaborateness and indirectness displayed. To this end, we examine the impact of elaborateness and ...
  • Nistal, Javier; Herrera Boyer, Perfecto, 1964-; Jordà Puig, Sergi (2017)
    We present a study on the behavior of human finger-tapping and the spontaneous expression of rhythm. For the purposes of this study we construe interpret finger-tapping as the casual and rhythmic hitting of objects for ...
  • Bonada, Jordi, 1973-; Umbert Morist, Martí; Blaauw, Merlijn (International Speech Communication Association (ISCA), 2016)
    Sample and statistically based singing synthesizers typically require a large amount of data for automatically generating expressive synthetic performances. In this paper we present a singing synthesizer that using two ...
  • Font Corbera, Frederic; Serra, Xavier (Springer, 2011)
    Sound and music online services driven by communities of users are filled with large amounts of user-created content that has to be properly described. In these services, typical sound and music modeling is performed using ...
  • Martínez, Elena; Celma Herrada, Òscar; Sordo, Mohamed; de Jong, Bram; Serra, Xavier ([Sound and Music Computing], 2009)
    This paper presents an in–depth study of the social tagging mechanisms used in Freesound.org, an online community where users share and browse audio files by means of tags and content–based audio similarity search. We ...
  • Espinosa-Anke, Luis; Camacho-Collados, Jose; Rodríguez Fernández, Sara; Saggion, Horacio; Wanner, Leo (COLING, 2016)
    WordNet is probably the best known lexical resource in Natural Language Processing. While it/nis widely regarded as a high quality repository of concepts and semantic relations, updating and/nextending it manually is costly. ...
  • Sordo, Mohamed; Oramas, Sergio; Espinosa-Anke, Luis (Springer, 2015)
    This paper presents a method for the generation of struc- tured data sources for music recommendation using information extracted from unstructured text sources. The proposed method identi es entities in text that are ...
  • 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/ninformation that could not otherwise be extracted/nfrom audio signals or symbolic score representations. In/nthis paper we propose a methodology for ...
  • Zehlike, Meike; Bonchi, Francesco; Castillo, Carlos; Hajian, Sara; Megahed, Mohamed; Baeza-Yates, Ricardo (ACM Association for Computer Machinery, 2017)
    In this work, we define and solve the Fair Top-k Ranking problem, in which we want to determine a subset of k candidates from a large pool of n>>k candidates, maximizing utility (i.e., select the “best” candidates) subject ...
  • Favory, Xavier; Fonseca, Eduardo; Font, Frederic; Serra, Xavier (FRUCT, 2018)
    Properly annotated multimedia content is crucial for supporting advances in many Information Retrieval applications. It enables, for instance, the development of automatic tools for the annotation of large and diverse ...
  • Jindal, Nihar; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    The purpose of this paper is to examine (1) some of the models commonly used to represent fading,/nand (2) the information-theoretic metrics most commonly used to evaluate performance over those models. We raise the question ...
  • Gialampoukidis, Ilias; Vrochidis, Stefanos; Kompatsiaris, Ioannis (Springer, 2016)
    Most of the image retrieval approaches nowadays are based on the Bag-of-Words (BoW) model, which allows for representing an image efficiently and quickly. The efficiency of the BoW model is related to the efficiency of the ...
  • Chamorro Servent, Judit; Aguirre, Juan; Ripoll, Jorge; Vaquero, Juan J.; Deseo, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    Fluorescence Enhanced Diffuse Optical Tomography (FDOT) retrieves 3D distributions of fluorophore concentration in small animals, non-invasively and in vivo. The FDOT problem can be formulated as a system of equations, ...
