  • 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, ...
  • Camacho-Collados, Jose; Delli Bovi, Claudio; Espinosa-Anke, Luis; Oramas, Sergio; Pasini, Tommaso; Santus, Enrico; Shwartz, Vered; Navigli, Roberto; Saggion, Horacio (ACL (Association for Computational Linguistics), 2018)
    This paper describes the SemEval 2018 Shared Task on Hypernym Discovery. We put forward this task as a complementary benchmark for modeling hypernymy, a problem which has traditionally been cast as a binary ...
  • Angelosante, Daniele; Biglieri, Ezio; Lops, Marco (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    In this paper, we introduce a pilot-aided multipath channel estimator for Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) systems. Typical estimation algorithms assume the number of ...
  • Haro Ortega, Gloria (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    We propose a 3D reconstruction algorithm based on silhouettes and color images. It is robust to inconsistent silhouettes, often common in real applications due to occlusions, errors in the background subtraction, noise or ...
  • Haro Ortega, Gloria (Institute of Electrical and Electronics Engineers (IEEE), 2014)
  • 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 ...
  • Özaslan, Tan Hakan; Serra, Xavier; Arcos, Josep Lluís (Universitat Pompeu Fabra, 2012)
    Ney is an end-blown flute which is mainly used for Makam music. Although from the beginning of 20th century a score representation based on extending the Western music/nis used, because of its rich articulation repertoire, ...
  • Biglieri, Ezio; Hong, Yi; Viterbo, Emanuele (European Association for Signal Processing (EURASIP), 2008)
    Silver Code (SilC) was originally discovered in [1–4] for 2×2 multiple-input multiple-output (MIMO) transmission. It has non-vanishing minimum determinant 1/7, slightly lower than Golden code, but is fast-decodable, i.e., ...
  • Herrera Boyer, Perfecto; Bello, Juan; Widmer, Gerhard; Sandler, Mark; Celma Herrada, Òscar; Vignoli, Fabio; Pampalk, Elias; Cano, Pedro; Pauws, Steffen; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2005)
    The SIMAC project addresses the study and development of innovative components for a music information retrieval system. The key feature is the usage and exploitation of semantic descriptors of musical content that are ...
  • de Boer, Marteen; Bonada, Jordi, 1973-; Cano, Pedro; Loscos, Àlex; Serra, Xavier (International Computer Music Conference, 2000)
    This paper presents the implementation aspects of a real-time system for morphing two voices in the context of a karaoke application. It describes the software design and implementation under a PC platform and it discusses ...
  • Gong, Rong; Serra, Xavier (International Speech Communication Association (ISCA), 2018)
    In this paper, we tackle the singing voice phoneme segmentation problem in the singing training scenario by using language independent information – onset and prior coarse duration. We propose a two-step method. In the ...
  • Bonada, Jordi, 1973-; Celma Herrada, Òscar; Loscos, Àlex; Ortolà, Jaume; Serra, Xavier; Yoshioka, Yasuo; Kayama, Hiraku; Hisaminato, Yuji; Kenmochi, Hideki (International Computer Music Conference, 2001)
    This paper presents an approach to the modeling of the singing voice with a particular emphasis on the naturalness of the resulting synthetic voice. The underlying analysis/synthesis technique is based on the Spectral ...
  • Farrús, Mireia; Anguita, Jan; Anguera Miró, Xavier, 1978-; Crego, Josep Maria; de Gispert, A.; Hernando, Javier; Nadeu Camprubí, Climent (2004)
    La visió actual de la societat de la informació gira fonamentalment al voltant de la llengua escrita. No obstant, és evident que la forma més natural i espontània de comunicació entre els éssers humans és la parla, i no ...
  • Schaper, Marie-Monique; Malinverni, Laura; Parés, Narcís, 1966- (ACM Association for Computer Machinery, 2015)
    The aim of this paper is to explore techniques to design specific gestures with children to improve the interaction design of a Full- Body Interaction Learning Environment. This exploratory case study is part of the ...
  • Lluch Alvarez, Èric; Doste, Rubén; Giffard-Roisin, Sophie; This, Alexandre; Sermesant, Maxime; Camara, Oscar; De Craene, Mathieu; Morales, Hernán G. (Springer, 2017)
    Finite element methods (FEM) are generally used in cardiac 3D-electromechanical modeling. For FEM modeling, a step of a suitable mesh construction is required, which is non-trivial and time-consuming for complex geometries. ...
  • Eakin, Richard Thomas; Serra, Xavier (International Conference on Digital Audio Effects, 2009)
    We present a real-time implementation of SMS synthesis in Pure Data. This instrument focuses on interaction with the ability to continuously synthesize any frame position within an SMS sound representation, in any order, ...
  • Purohit, Hemant; Castillo, Carlos; Imran, Muhammad; Pandey, Rahul (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    The public expects a prompt response from emergency services to address requests for help posted on social media. However, the information overload of social media experienced by these organizations, coupled with their ...
  • Furelos Blanco, Daniel; Jonsson, Anders, 1973- (Association for the Advancement of Artificial Intelligence (AAAI) - Congrés ICAPS17, 2018)
    In this work we present a novel approach to solving concurrent multiagent planning problems in which several agents act in parallel. Our approach relies on a compilation from concurrent multiagent planning to classical ...
  • Angelosante, Daniele; Biglieri, Ezio; Lops, Marco (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    This paper aims at illustrating some applications of Finite Random Set (FRS) theory to the design and analysis of wireless communication receivers, and at pointing out similarities and differences between this scenario and ...
