  • Gialampoukidis, Ilias; Vrochidis, Stefanos; Kompatsiaris, Ioannis; Wanner, Leo (Springer, 2016)
    Nowadays there is an important need by journalists and media monitoring companies to cluster news in large amounts of web articles, in order to ensure fast access to their topics or events of interest. Our aim in this work ...
  • Ballesteros, Miguel; Wanner, Leo (ACL (Association for Computational Linguistics), 2016)
    Even syntactically correct sentences are perceived as awkward if they do not contain correct punctuation. Still, the problem of automatic generation of punctuation marks has been largely neglected for a long time. We/npresent ...
  • Nazar, Rogelio (Universitat Pompeu Fabra, 2010-10-01)
    The present research focuses on the study of the distribution of lexis in corpus and its aim is to inquire into the relations that exist between concepts through the occurrences of the terms that designate them. The initial ...
  • 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 ...
  • 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 ...
  • Domínguez Bajo, Mónica; Farrús, Mireia; Wanner, Leo (COLING, 2016)
    Speech prosody is known to be central in advanced communication technologies. However, despite the advances of theoretical studies in speech prosody, so far, no large scale prosody annotated resources that would facilitate ...
  • 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. ...
  • Domínguez Bajo, Mónica; Farrús, Mireia; Wanner, Leo (International Speech Communication Association (ISCA), 2016)
    Intonation is traditionally considered to be the most important prosodic feature, whereupon an important research effort has been devoted to automatic segmentation and labeling of speech samples to grasp intonation cues. ...
  • Ballesteros, Miguel; Bohnet, Bernd; Mille, Simon; Wanner, Leo (Cambridge University Press, 2016)
    ‘Deep-syntactic’ dependency structures that capture the argumentative, attributive and co-/nordinative relations between full words of a sentence have a great potential for a number/nof NLP-applications. The abstraction ...
  • Ballesteros, Miguel; Bohnet, Bernd; Mille, Simon; Wanner, Leo (ACL (Association for Computational Linguistics), 2015)
    Abstract structures from which the generation naturally starts often do not contain any functional nodes, while surface-syntactic structures or a chain of tokens in a linearized tree contain all of them. Therefore, data-driven ...
  • Mille, Simon (Universitat Pompeu Fabra, 2014-07-25)
    The present Ph.D. thesis addresses the problem of deep data-driven Natural Language Generation (NLG), and in particular the role of proper corpus annotation schemata for stochastic sentence realization. The lack of multilevel ...
  • Rodríguez Fernández, Sara; Carlini, Roberto; Espinosa-Anke, Luis; Wanner, Leo (ELRA (European Language Resources Association), 2016)
    Collocations such as heavy rain or make [a] decision, are combinations of two elements where one (the base) is freely chosen, while the/nchoice of the other (collocate) is restricted, depending on the base. Collocations ...
  • Espinosa-Anke, Luis; Camacho-Collados, Jose; Rodríguez Fernández, Sara; Saggion, Horacio; Wanner, Leo (COLING, 2016)
    WordNet is probably the best known lexical resource in Natural Language Processing. While it/nis widely regarded as a high quality repository of concepts and semantic relations, updating and/nextending it manually is costly. ...
  • Soler Company, Juan (Universitat Pompeu Fabra, 2017-07-06)
    Author profiling and identification are two areas of data-driven computational linguistics that have gained a lot of relevance due to their potential applications in, e.g., forensic linguistic studies, marketing analysis, ...
  • 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 ...
  • Cunha Fanego, Iria da (Universitat Pompeu Fabra, 2008-04-25)
    En esta tesis se presenta un modelo lingüístico de resumen automático de artículos médicos en español que aúna criterios basados en la estructura textual, en las unidades léxicas y la estructura discursiva y sintáctico-c ...
  • Domínguez Bajo, Mónica; Latorre, Iván; Farrús, Mireia; Codina-Filbà, Joan; Wanner, Leo (COLING, 2016)
    This paper presents an implementation of the widely used speech analysis tool Praat as a web application with an extended functionality for feature annotation. In particular, Praat on the Web addresses some of the central ...
  • 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 ...
  • 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 ...
  • Cunha Fanego, Iria da; Wanner, Leo; Cabré, M. Teresa (Maria Teresa), 1947- (John Benjamins Publishing, 2007)
    In this article, we present the current state of our work on a linguistically-motivated model for automatic summarization of medical articles in Spanish. The model takes into account the results of an empirical study which ...
