  • Prieto, Luis P.; Martínez-Maldonado, Roberto; Spikol, Daniel; Hernández Leo, Davinia; Rodríguez-Triana, María Jesús; Ochoa, Xavier (CEUR Workshop Proceedings, 2017)
    Learning is a complex, mostly invisible process that happens across spaces, occurring in the physical world but also increasingly in virtual worlds or web-based spaces. In order to explore what happens in such blended ...
  • 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 ...
  • Gialampoukidis, Ilias; Vrochidis, Stefanos; Kompatsiaris, Ioannis; Antoniou, Ioannis (2017)
    Topic detection is usually considered as a decision process implemented in some relevant context, for example clustering. In this case, clusters correspond to topics that should be identifed. Density-based clustering, ...
  • Ten-Ventura, Carla; Carlini, Roberto; Dasioupoulou, Stamatia; LLorach Tó, Gerard; Wanner, Leo (Springer, 2017)
    We present work in progress on (verbal, facial, and gestural) modality selection in an embodied multilingual and multicultural conversation agent. In contrast to most of the recent proposals, which consider non-verbal ...
  • Burga Díaz, Alicia; Cajal, Sergio; Codina-Filbà, Joan; Wanner, Leo (LREC, 2016)
    Despite the popularity of coreference resolution as a research topic, the overwhelming majority of the work in this area focused so far on single antecedence coreference only. Multiple antecedent coreference (MAC) has been ...
  • Soler Company, Juan; Wanner, Leo (LREC, 2016)
    In most of the research studies on Author Profiling, large quantities of correctly labeled data are used to train the models. However, this does not reflect the reality in forensic scenarios: in practical linguistic forensic ...
  • Giménez Mínguez, Paula; Bijnens, Bart; Bernardino Perez, Gabriel; Lluch Alvarez, Èric; Soveral, Iris; Gómez, Olga; García Cañadilla, Patricia, 1985- (Springer, 2017)
    Introduction: Aortic coarctation is one of the most difficult cardiac defects to diagnose before birth, and it accounts for 8% of congenital heart diseases. Antenatal diagnosis is crucial for early treatment of the neonate ...
  • Wang, Xingce; Liu, Yue; Wu, Zhongke; Mou, Xiao; Zhou, Mingquan; González Ballester, Miguel Ángel, 1973-; Zhang, Chong (2017)
    Identifcation of anatomical vessel branches is a prerequisite task for diagnosis, treatment and inter-subject comparison. We propose a novel graph labeling approach to anatomically label vascular structures of interest. ...
  • Luque, Jordi; Morros, R.; Garde, I.; Anguita, Jan; Farrús, Mireia; Macho, D.; Marqués, F.; Martínez, C.; Vilaplana, V.; Hernando, Javier (Springer, 2007)
    In this paper, we address the modality integration issue on the example of a smart room environment aiming at enabling person identification by combining speech and 2D face images. First we introduce the monomodal audio ...
  • Villarejo Muñoz, Luis; Farrús, Mireia; Ortiz, Sergio; Ramírez, Gemma (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    In this paper, we describe the adaptation process of Apertium, a free/open-source rule-based machine translation platform which is operating in a number of different real-life contexts, to the linguistic needs of the ...
  • Ruiz, Adrià; Martinez, Oriol; Binefa i Valls, Xavier; Sukno, Federico M. (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    An essential issue when training and validating computer vision systems for affect analysis is how to obtain reliable ground-truth labels from a pool of subjective annotations. In this paper, we address this problem ...
  • Fernandez-Lopez, Adriana; Martinez, Oriol; Sukno, Federico M. (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Speech is the most used communication method between humans and it involves the perception of auditory and visual channels. Automatic speech recognition focuses on interpreting the audio signals, although the video can ...
  • Mille, Simon; Carlini, Roberto; Burga Díaz, Alicia; Wanner, Leo (ACL (Association for Computational Linguistics), 2017)
    We present the contribution of Universitat Pompeu Fabra’s NLP group to the Sem-Eval Task 9.2 (AMR-to-English Generation). The proposed generation pipeline comprises: (i) a series of rule-based graphtransducers for the ...
  • Miehle, Juliana; Bagci, Ilker; Minker, Wolfgang; Ultes, Stefan (2017)
    In this work, we present the development and evaluation of a social companion and conversation partner for the special user group of elderly.With the aim of designing a user-adaptive system, we responded to the desires ...
  • Pragst, Louisa; Minker, Wolfgang; Ultes, Stefan (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 ...
  • Öktem, Alp; Farrús, Mireia; Wanner, Leo (2017)
    This paper presents an open-source tool that has been developed to visualize a speech corpus with its transcript and prosodic features aligned at word level. In particular, the tool is aimed at providing a simple and clear ...
  • Domínguez Bajo, Mónica; Farrús, Mireia; Wanner, Leo (2017)
    This paper presents a demonstration of a stochastic prosody tool for enrichment of synthesized speech using SSML prosody tags applied over hierarchical thematicity spans in the context of a CTS application. The motivation ...
  • Kleinhans, Janine; Farrús, Mireia; Gravano, Agustín; Pérez, Juan Manuel; Lai, Catherine; Wanner, Leo (2017)
    This work aims to explore the correlation between the discourse structure of a spoken monologue and its prosody by predicting discourse relations from different prosodic attributes. For this purpose, a corpus of semi-spontaneous ...
  • Öktem, Alp; Farrús, Mireia; Wanner, Leo (ACL (Association for Computational Linguistics), 2017)
    This paper presents a methodology to extract parallel speech corpora based on any language pair from dubbed movies, together with an application framework in which some corresponding prosodic parameters are extracted. ...
  • Nogueira, Mariana; Piella Fenoy, Gemma; Sanchez Martinez, Sergio; Langet, Hélène; Saloux, Eric (Springer, 2017)
    In this paper, we capture patterns of response to cardiac stress-testing using a multiview dimensionality reduction technique that allows the compact representation of patient response to stress, regarding multiple features ...
