  • 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 ...
  • Evans, Alun Thomas; Agenjo, Javier; Blat, Josep (ACM Association for Computer Machinery, 2014)
    In this paper we present a system for progressive encoding, storage, transmission, and web based visualization of large point cloud datasets. Point cloud data is typically recorded on-set during a film production, and is ...
  • 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 ...
  • Laniado, David; Tasso, Riccardo; Volkovich, Yana; Kaltenbrunner, Andreas (Association for the Advancement of Artificial Intelligence (AAAI), 2011)
    Talk pages play a fundamental role in Wikipedia as the place for discussion and communication. In this work we use the comments on these pages to extract and study three networks, corresponding to different kinds of ...
  • Oliver Riera, Miquel; Salas, Francisco (Americas Information and Communications Research Network, 2017)
    TV White Spaces is a cost-effective solution to provide broadband Internet in rural and remote areas. Several TVWS pilots and testbeds are now being deployed to explore the limitations of such technology. Some Latin American ...
  • Geffner, Héctor; Lipovetzky, Nir (IOS Press, 2012)
    We introduce a width parameter that bounds the complexity of classical planning problems and domains, along with a simple but effective blind-search procedure that runs in time that is exponential in the problem width. We ...
  • Freire, Ana; Ruiz-Garcia, Aurelio; Moreno Oliver, Verónica (ACPI - Academic Conferences and Publishing International Limited, 2018)
    Although technology comprises an important part of our daily life, no matter your gender, women are underrepresented in the overall sector of Information and Communications Technologies (ICT). Among several reasons, ...
  • Ferrés, Daniel; Marimon, Montserrat; Saggion, Horacio; AbuRa’ed, Ahmed (Springer, 2016)
    We present a text simplifier for English that has been built with open source software and has both lexical and syntactic simplification capabilities. The lexical simplifier uses a vector space model approach to obtain the ...
