  • 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, ...
  • Agerri, Rodrigo; Aldabe, Itziar; Laparra, Egoitz; Rigau Claramunt, German; Fokkens, Antske; Huijgen, Paul; Izquierdo Beviá, Rubén; van Erp, Marieke; Vossen, Piek; Minard, Anne-Lyse; Magnini, Bernardo (International Conference on Language Resources and Evaluation (LREC), 2016)
    We describe a novel modular system for cross-lingual event extraction for English, Spanish,, Dutch and Italian texts. The system consists of a ready-to-use modular set of advanced multilingual Natural Language Processing ...
  • Rach, Niklas; Minker, Wolfgang; Ultes, Stefan (ACL (Association for Computational Linguistics), 2017)
    For estimating the Interaction Quality (IQ) in Spoken Dialogue Systems (SDS), the dialogue history is of significant importance. Previous works included this information manually in the form of precomputed temporal features ...
  • Oramas, Sergio; Sordo, Mohamed; Espinosa-Anke, Luis (ACM Association for Computer Machinery, 2015)
    This paper presents a rule based approach to extracting relations from unstructured music text sources. The proposed approach identifies and disambiguates musical entities in text, such as songs, bands, persons, albums and ...
  • Oramas, Sergio; Nieto Caballero, Oriol; Sordo, Mohamed; Serra, Xavier (ACM Association for Computer Machinery, 2017)
    An increasing amount of digital music is being published daily. Music streaming services often ingest all available music, but this poses a challenge: how to recommend new artists for which prior knowledge is scarce? In ...
  • Fonseca, Eduardo; Gong, Rong; Bogdanov, Dmitry; Slizovskaia, Olga; Gómez Gutiérrez, Emilia, 1975-; Serra, Xavier (Tampere University of Technology, 2017)
    This work describes our contribution to the acoustic scene classifi- cation task of the DCASE 2017 challenge. We propose a system that consists of the ensemble of two methods of different nature: a feature engineering ...
  • Oramas, Sergio; Sordo, Mohamed; Serra, Xavier (Society for Interdisciplinary Musicology, 2014)
    Most of the current musicological knowledge is present in printed books and manuscripts. In the last years greats efforts have been done in order to digitize and make available these documents in form of Digital Libraries. ...
  • Oramas, Sergio; Gómez, Francisco; Gómez Gutiérrez, Emilia, 1975-; Mora, Joaquín (International Society for Music Information Retrieval (ISMIR), 2015)
    Online information about flamenco music is scattered over different sites and knowledge bases. Unfortunately, there is no common repository that indexes all these data. In this work, information related to flamenco ...
  • Senanayake, Rajitha; Lozano Solsona, Angel; Smith, Peter; Evans, Jamie (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    This paper considers distributed massive MIMO networks where a large number of antennas, either collocated or geographically scattered over a region, communicate with mobile users. This communication is impaired by ...
  • George, Geordie; Mungara, Ratheesh K.; Lozano Solsona, Angel; Haenggi, Martin (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    The application of stochastic geometry to the analysis of wireless networks is shown to be propelled by (i) a clean separation of time scales, (ii) abstraction of small-scale effects via ergodicity, and (iii) an interference ...
  • Cerdà, Ramon; Farrús, Mireia; Hernando, Javier; Veyrat Rigat, Montserrat (Dirección Xeral de Creación e Difusión Cultural, 2007)
    La presente comunicación no ofrece todavía resultados de ningún experimento ya ejecutado, sino, com su título indica, una serie de comentarios en torno a la noción de "campo de dispersión fonemática" (o "fonológica") o ...
  • Farrús, Mireia; Anguita, Jan; Hernando, Javier; Cerdà, Ramon (Dirección Xeral de Creación e Difusión Cultural, 2007)
    Los sistemas automáticos de reconocimiento de locutor más utilizados recientemente están basados en características acústicas de bajo nivel, como las magnitudes espectrales, las frecuencias de los formantes, etc. Sin ...
  • Farrús, Mireia; Erro, Daniel; Hernando, Javier (Universidad de Valladolid, 2008)
    Security systems relying on voice identification can be threatened by human voice imitation or synthetic voices. As voice conversion can be seen as a sort of voice imitation, this paper analyses the performance of an ...
  • Leiva, Víctor; Freire, Ana (Springer, 2017)
    The statistics presented by the World Health Organization inform that 90% of the suicides can be attributed to mental illnesses in high-income countries. Besides, previous studies concluded that people with mental illnesses ...
  • Barbieri, Francesco; Espinosa-Anke, Luis; Ballesteros, Miguel; Soler Company, Juan; Saggion, Horacio (ACL (Association for Computational Linguistics), 2017)
    Videogame streaming platforms have become a paramount example of noisy usergenerated text. These are websites where gaming is broadcasted, and allows interaction with viewers via integrated chatrooms. Probably the ...
  • Barbieri, Francesco; Ballesteros, Miguel; Saggion, Horacio (ACL (Association for Computational Linguistics), 2017)
    Emojis are ideograms which are naturally combined with plain text to visually complement or condense the meaning of a message. Despite being widely used in social media, their underlying semantics have received little ...
  • Fonseca, Eduardo; Pons Puig, Jordi; Favory, Xavier; Font Corbera, Frederic; Bogdanov, Dmitry; Ferraro, Andrés; Oramas, Sergio; Porter, Alastair; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2017)
    Openly available datasets are a key factor in the advancement of data-driven research approaches, including many of the ones used in sound and music computing. In the last few years, quite a number of new audio datasets ...
  • Perez Miguel, Naiara; Cuadros Oller, Montse (ACL (Association for Computational Linguistics), 2017)
    This paper describes a web-based application to design and answer exercises for language learning. It is available in Basque, Spanish, English, and French. Based on open-source Natural Language Processing (NLP) ...
  • 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 ...
