  • Albó Pérez, Laia; Hernández Leo, Davinia; Barceló, Jaume; Sanabria Russo, Luis (European Distance and E-Learning Network, 2015)
    Nowadays Higher Education is adopting new ways of teaching such as ways of Video-Based Learning (VBL) with the/naim of moving away from the traditional classrooms. The interest in VBL has increased as a result of new forms ...
  • Gómez Gutiérrez, Emilia, 1975-; Arias Martínez, Pablo; Zinemanas, Pablo; Haro Ortega, Gloria (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Automatic transcription is a well-known task in the music information retrieval (MIR) domain, and consists on the computation of a symbolic music representation (e.g. MIDI) from an audio recording. In this work, we address ...
  • Aragón, Pablo; Gómez, Vicenç; Kaltenbrunner, Andreas (Association for the Advancement of Artificial Intelligence (AAAI), 2016)
    Online debate tools for participatory democracy and crowdsourcing legislation are limited by different factors. One of them arises when discussion of proposals reaches a large number of contributions and therefore ...
  • Soler Company, Juan; Ballesteros, Miguel; Bohnet, Bernd; Mille, Simon; Wanner, Leo (ACL (Association for Computational Linguistics), 2015)
    “Deep-syntactic” dependency structures bridge the gap between the surface-syntactic structures as produced by state-of-the-art dependency parsers and semantic logical forms in that they abstract away from surfacesyntactic ...
  • Cano, Pedro; Loscos, Àlex; Bonada, Jordi, 1973-; de Boer, Marteen; Serra, Xavier (International Computer Music Conference, 2000)
    In this paper we present a real-time system for morphing two voices in the context of a karaoke application. As the user sings a pre-established song, his pitch, timbre, vibrato and articulation can be modified to resemble ...
  • Vera, Sergio; González Ballester, Miguel Ángel, 1973-; Gil, Debora (Technical University of Denmark, 2013)
    A coordinate system parameterizing the interior of organs is/na powerful tool for a systematic localization of injured tissue. If the same/ncoordinate values are assigned to speci c anatomical sites, parameterizations/nensure ...
  • Espinosa-Anke, Luis; Ronzano, Francesco; Saggion, Horacio (ACL (Association for Computational Linguistics), 2015)
    Definition Extraction (DE) is the task to extract textual definitions from naturally occurring text. It is gaining popularity as a prior step for constructing taxonomies, ontologies, automatic glossaries or dictionary ...
  • Llorach, Gerard; Evans, Alun Thomas; Blat, Josep; Grimm, Giso; Hohmann, Volker (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Virtual characters are an integral part of many games and virtual worlds. The ability to accurately synchronize lip movement to audio speech is an important aspect in the believability of the character. In this paper we ...
  • Barbieri, Francesco; Ronzano, Francesco; Saggion, Horacio (ELRA (European Language Resources Association), 2016)
    Emojis allow us to describe objects, situations and even feelings with small images, providing a visual and quick way to communicate. In this paper, we analyse emojis used in Twitter with distributional semantic models. ...
  • Urbano, Julián; Bogdanov, Dmitry; Herrera Boyer, Perfecto; Gómez Gutiérrez, Emilia, 1975-; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2014)
    Music Information Retrieval is largely based on descriptors computed from audio signals, and in many practical applications they are to be computed on music corpora containing audio files encoded in a variety of lossy ...
  • Jindal, Nihar; Lozano Solsona, Angel; Marzetta, Thomas L. (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    The spectral efficiency achievable with joint processing of pilot and data symbol observations is compared with that achievable through the conventional (separate) approach of first estimating the channel on the basis of ...
  • AbuRa’ed, Ahmed; Chiruzzo, Luis; Saggion, Horacio (ACL (Association for Computational Linguistics), 2017)
    In the current context of scientific information overload, text mining tools are of paramount importance for researchers who have to read scientific papers and assess their value. Current citation networks, which link ...
  • Aragón, Pablo; Volkovich, Yana; Laniado, David; Kaltenbrunner, Andreas (Association for the Advancement of Artificial Intelligence (AAAI), 2016)
    Social media has become a key mechanism for the organization of grassroots movements. In the 2015 Barcelona City Council election, Barcelona en Com´u, an emerging grassroots party, was the most voted one. This candidacy ...
