  • Arcos, Josep Lluís; López de Mántaras, Ramon; Serra, Xavier (International Computer Music Conference, 1997)
    We have studied the problem of generating expressive musical performances in the context of tenor saxophone interpretations. We have done several recordings of a tenor sax playing dierent Jazz ballads with dierent degrees ...
  • Smeros, Panayiotis; Castillo, Carlos; Aberer, Karl (ACM Association for Computer Machinery, 2019)
    This paper describes, develops, and validates SciLens, a method to evaluate the quality of scientific news articles. The starting point for our work are structured methodologies that define a series of quality aspects for ...
  • Sentürk, Sertan; Gulati, Sankalp; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2013)
    Tonic is a fundamental concept in many music traditions/nand its automatic identification should be relevant for establishing/nthe reference pitch when we analyse the melodic/ncontent of the music. In this paper, we present ...
  • Pons Puig, Jordi; Gong, Rong; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2017)
    This paper introduces a new score-informed method for the segmentation of jingju a cappella singing phrase into syllables. The proposed method estimates the most likely sequence of syllable boundaries given the estimated ...
  • Gong, Rong; Obin, Nicolas; Dzhambazov, Georgi Bogomilov; Serra, Xavier (Folk Music Analysis, 2017)
    This paper introduces a new unsupervised and score-informed method for the segmentation of singing voice into syllables. The main idea of the proposed method is to detect the syllable onset on a probability density ...
  • Lipovetzky, Nir; Geffner, Héctor (Association for the Advancement of Artificial Intelligence (AAAI), 2011)
    We define a probe to be a single action sequence computedgreedily from a given state that either terminates in the goalor fails. We show that by designing these probes carefullyusing a number of existing and new polynomial ...
  • Dzhambazov, Georgi Bogomilov; Sentürk, Sertan; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2015)
    Search by lyrics, the problem of locating the exact occurrences of a phrase from lyrics in musical audio, is a recently emerging research topic. Unlike key-phrases in speech, lyrical key-phrases have durations that bear ...
  • Anguera Miró, Xavier, 1978-; Farrús, Mireia; Hernando, Javier (2004)
    L'evolució de la societat de la informació ha esdevingut un incessant increment de continguts audiovisuals que s’emeten constantment en cadenes de televisió i emissores de radio locals i nacionals en llengua catalana. ...
  • Castellví Fernández, Quim; Sánchez-Velázquez, Joan; Berjano, Enrique J.; Burdío Pinilla, Fernando; Ivorra Cano, Antoni, 1974- (Springer, 2015)
    Spread tumors in liver are not suitable to be treated with local treatments, such as conventional surgery or radiofrequency ablation, thus entailing a poor prognosis. Electroporation-based therapies imply the delivery of ...
  • Vitoria, Patricia; Sintes Marcos, Joan; Ballester, Coloma (SCITEPRESS, 2019)
    Image inpainting is the task of filling-in missing regions of a damaged or incomplete image. In this work we tackle this problem not only by using the available visual data but also by incorporating image semantics through ...
  • 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 ...
  • Rodríguez Fernández, Sara; Espinosa-Anke, Luis; Carlini, Roberto; Wanner, Leo (ACL (Association for Computational Linguistics), 2016)
    L2 learners often produce “ungrammatical” word combinations such as, e.g., *give a suggestion or *make a walk. This is because of the “collocationality” of one of their items (the base) that limits the acceptance of ...
  • Barbieri, Francesco; Camacho-Collados, Jose; Ronzano, Francesco; Espinosa-Anke, Luis; Ballesteros, Miguel; Basile, Valerio; Patti, Viviana; Saggion, Horacio (ACL (Association for Computational Linguistics), 2018)
    This paper describes the results of the first shared task on Multilingual Emoji Prediction, organized as part of SemEval 2018. Given the text of a tweet, the task consists of predicting the most likely emoji to be used ...
  • 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 ...
  • Vujovic, Milica; Hernández Leo, Davinia (2019)
    In this paper we question the role of environmental sound on the process of CL. The first pilot study is presented where we investigated effects of environmental sound on EDA and voice VA of the participants. The created ...
  • Haro Ortega, Gloria (Institute of Electrical and Electronics Engineers (IEEE), 2014)
  • 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 ...
