    This paper presents an interactive multimedia search engine, which is capable of searching into multimedia collections by fusing textual and visual information. Apart from multimedia search, the engine is able to perform ...
  • Gialampoukidis, Ilias; Moumtzidou, Anastasia; Liparas, Dimitris; Vrochidis, Stefanos; Kompatsiaris, Ioannis (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Nowadays, multimedia retrieval has become a task of high importance, due to the need for efficient and fast access to very large and heterogeneous multimedia collections. An interesting challenge within the aforementioned ...

  • Bijnens, Bart; Cardenes, Rubén; Sebastián Aguilar, Rafael, 1978-; Soto-Iglesias, David; Andreu Martínez, David; Fernández-Armenta, Juan; Berruezo Sánchez, Antonio; Camara, Oscar (Springer, 2014)
    The electrical activation of the heart is a complex physiological process that is essential for the understanding of several cardiac dysfunctions, such as ventricular tachycardia (VT). Nowadays, electro-anatomical mappings ...
  • Gialampoukidis, Ilias; Moumtzidou, Anastasia; Tsikrika, Theodora; Vrochidis, Stefanos; Kompatsiaris, Ioannis (ACM Association for Computer Machinery, 2016)
    Searching for multimedia objects with heterogeneous modal- ities is critical for the construction of e ective multimedia retrieval systems. Towards this direction, we propose a framework for the multimodal fusion of visual ...
  • Llorach, Gerard; Evans, Alun Thomas; Blat, Josep; Grimm, Giso; Hohmann, Volker (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Virtual characters are an integral part of many games and virtual worlds. The ability to accurately synchronize lip movement to audio speech is an important aspect in the believability of the character. In this paper we ...
  • 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 ...
  • Farrús, Mireia (Universitat de Barcelona, 2011)
    La biometria té com a objectiu el reconeixement de persones mitjançant un o més identificadors biomètrics com la veu, la cara o les empremtes dactilars, entre d'altres. Gràcies a la bona acceptació social i el poc intrusisme ...
  • Farrús, Mireia; Noguera, Ingrid; Santanach, Francesc; Moré, Quim; López Pérez, Cristina; Appel, Christine (Col·legi Oficial de Bibliotecaris-Documentalistes de Catalunya, 2011)
    Durant les últimes dècades, en un context en què impera la influència de les TIC, el model de l'ensenyament universitari ha canviat radicalment. Paral·lelament, els rols de l'estudiant i del professor també s'han vist ...
  • 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 ...
  • Andrzejak, Ralph Gregor; Laiou, Petroula (American Physical Society, 2017)
    The understanding of interacting dynamics is important for the characterization of real-world/nnetworks. In general real-world networks are heterogeneous in the sense that each node of the/nnetwork is a dynamics with di ...
  • 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)
