  • Buckman, Jacob; Ballesteros, Miguel; Dyer, Chris (ACL (Association for Computational Linguistics), 2016)
    We introduce a novel approach to the decoding problem in transition-based parsing: heuristic backtracking. This algorithm uses a series of partial parses on the sentence to locate the best candidate parse, using confidence ...
  • Espinosa-Anke, Luis; Camacho-Collados, Jose; Rodríguez Fernández, Sara; Saggion, Horacio, 1963-; 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. ...
  • Lai, Catherine; Farrús, Mireia; Moore, Johanna D. (International Speech Communication Association (ISCA), 2016)
    As long-form spoken documents become more ubiquitous in everyday life, so does the need for automatic discourse segmentation in spoken language processing tasks. Although previous work has focused on broad topic segmentation, ...
  • Farrús, Mireia; Serra, Montse; Basart i Muñoz, Josep M.; Nadeu Camprubí, Climent (CIDUI Congrés Internacional de Docència Universitària i Innovació, 2016)
    En aquesta comunicació presentem una sèrie d'elements de protagonisme de l'alumne, treballats en una aula d'informàtica, amb l'objectiu de fomentar la participació de l'alumne a la classe. Aquests elements, que inclouen ...
  • Doulaverakis, Charalampos; Vrochidis, Stefanos; Kompatsiaris, Ioannis (SCITEPRESS, 2015)
    Ontology alignment is the process where two different ontologies that usually describe similar domains are ’aligned’, i.e. a set of correspondences between their entities, regarding semantic equivalence, is determined. In ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Meditskos, Georgios; Dasiopoulou, Stamatia; Pragst, Louisa; Ultes, Stefan; Vrochidis, Stefanos; Wanner, Leo (ACM Association for Computer Machinery, 2016)
    In this paper, we describe the principles and technologies that underpin the development of an adaptive dialogue manager framework, tailored to carrying out human-agent conversations in a natural, robust and exible ...
  • Meditskos, Georgios; Dasiopoulou, Stamatia; Vrochidis, Stefanos; Kompatsiaris, Ioannis (ACM Association for Computer Machinery, 2016)
    In this paper we present an ontology-driven framework for natural language question analysis and answering over user models (e.g. preferences, habits and health problems of individuals) that are formally captured using ...
  • Andreadis, Stelios; Stavropoulos, Thanos G.; Meditskos, Georgios; Kompatsiaris, Ioannis (CEUR Workshop Proceedings, 2016)
    With the ever-growing prevalence of dementia, nursing costs are in-creasing, while the ability to live independently vanishes. Dem@Home is an ambient assisted living framework to support independent living while receiv-ing ...
  • Dyer, Chris; Ballesteros, Miguel; Ling, W; Matthews, A; Smith, Noah A. (ACL (Association for Computational Linguistics), 2015)
    We propose a technique for learning representations of parser states in transitionbased dependency parsers. Our primary innovation is a new control structure for sequence-to-sequence neural networks— the stack LSTM. Like ...
  • Ahire, Amit L.; Evans, Alun Thomas; Blat, Josep (ACM Association for Computer Machinery, 2015)
    The main motivation of this paper is to provide a current state and a brief overview of animation on the web. Computer animation is used in many fields and it has seen a lot of development in the recent years. With the ...
  • Moulin-Frier, Clément; Sánchez-Fibla, Martí; Verschure, Paul F. M. J. (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    We provide an original computational model showing how turn-taking behaviors can self-organize out of sensorimotor/ninteractions between vocalizing agents. These agents are equipped with a cognitive architecture based on ...
  • Domínguez Bajo, Mónica; Farrús, Mireia; Burga Díaz, Alicia; Wanner, Leo (ISCA, 2014)
    This paper deals with the adaptation of AuToBI annotation for speech synthesis purposes. AuToBI is a tool that automatically determines and classifies the standard ToBI labels for American English. AuToBI annotation is ...
  • Domínguez Bajo, Mónica; Farrús, Mireia; Burga Díaz, Alicia; Wanner, Leo (ISCA, 2014)
    Several grammar theories relate information structure and prosody, highlighting a major correspondence between theme and rheme, and intonation patterns. Although these theories have been successfully exploited in some ...
  • Farrús, Mireia; Lai, Catherine; Moore, Johanna D. (International Speech Communication Association, 2016)
    Speech synthesis has improved in both expressiveness and voice quality in recent years. However, obtaining full expressiveness when dealing with large multi-sentential synthesized discourse is still a challenge, since ...
  • Espinosa-Anke, Luis; Carlini, Roberto; Saggion, Horacio, 1963-; Ronzano, Francesco (European Language Resources Association, 2016)
    We present DEFEXT, an easy to use semi supervised Definition Extraction Tool. DEFEXT is designed to extract from a target corpus those textual fragments where a term is explicitly mentioned together with its core features, ...
  • Oramas, Sergio; Espinosa-Anke, Luis; Sordo, Mohamed; Saggion, Horacio, 1963-; Serra, Xavier (European Language Resources Association, 2016)
    In this paper we present a gold standard dataset for Entity Linking (EL) in the Music Domain. It contains thousands of musical named entities such as Artist, Song or Record Label, which have been automatically annotated ...
  • Espinosa-Anke, Luis; Saggion, Horacio, 1963-; Delli Bovi, Claudio (CEUR, 2015)
    De nition Extraction is the task to identify snippets of free text in which/na term is de ned. While lexicographic studies have proposed di erent de nition typologies and categories, most NLP tasks aimed at revealing word ...
