  • Marimon, Montserrat; Bel Rafecas, Núria (ACL (Association for Computational Linguistics), 2004)
    We report on the development and employment of lexical entry templates in a large–coverage unification–based grammar of Spanish. The aim of the work reported in this paper is to provide robust deep linguistic processing ...
  • Bel Rafecas, Núria (ACL (Association for Computational Linguistics), 2010)
    We propose a strategy to reduce the impact of the sparse data problem in the tasks of lexical information acquisition based on the observation of linguistic cues. It justifies that the uncertainty created by missing values, ...
  • Fomicheva, Marina; Bel Rafecas, Núria; Da Cunha Fanego, Iria; Malinovskiy, Anton (ACL (Association for Computational Linguistics), 2015)
    An important limitation of automatic evaluation metrics is that, when comparing Machine Translation (MT) to a human reference, they are often unable to discriminate between acceptable variation and the differences that are ...
  • Francopoulo, Gil; Bel Rafecas, Núria; George, Monte; Calzolari, Nicoletta; Monachini, Monica; Pet, Mandy; Soria, Claudia (ACL (Association for Computational Linguistics), 2006)
    Optimizing the production, maintenance and extension of lexical resources is one the crucial aspects impacting Natural Language Processing (NLP). A second aspect involves optimizing the process leading to their integration ...
  • Marimon, Montserrat; Bel Rafecas, Núria; Espeja, Sergio; Seghezzi, Natalia (ACL (Association for Computational Linguistics), 2007)
    This paper describes work on the development of an open-source HPSG grammar for Spanish implemented within the LKB system. Following a brief description of the main features of the grammar, we present our approach for ...
  • Martínez Alonso, Héctor; Sandford Pedersen, Bolette; Bel Rafecas, Núria (ACL (Association for Computational Linguistics), 2013)
    We present the result of an annotation task on regular polysemy for a series of semantic classes or dot types in English, Danish and Spanish. This article describes the annotation process, the results in terms of inter-encoder ...
  • Poch, Marc; Bel Rafecas, Núria; Espeja, Sergio; Navío, Felipe (ACL (Association for Computational Linguistics), 2014)
    This paper presents a system for suggesting a ranked list of appropriate vacancy descriptions to job seekers in a job board web site. In particular our work has explored the use of supervised classifiers with the objective ...
  • Bel Rafecas, Núria; Pocostales, Joel (ACL (Association for Computational Linguistics), 2018)
    Aspect identification in user generated texts by supervised text classification might suffer degradation in performance when changing to other domains than the one used for training. For referring to aspects such as quality, ...
  • Romeo, Lauren; Martínez Alonso, Héctor; Bel Rafecas, Núria (ACL (Association for Computational Linguistics), 2013)
    This paper describes an effort to capture the sense alternation of dot-type nominals using Word Sense Induction (WSI). We propose dot-type nominals generate more semantically consistent groupings when clustered into more ...
  • Romeo, Lauren; Mendes, Sara; Bel Rafecas, Núria (ACL (Association for Computational Linguistics), 2013)
    The work presented here depicts experiments toward the automatic classification of complex-type nominals using distributional information. We conducted two experiments: classifying complex-type nominals as members of ...
  • Romeo, Lauren; Lebani, Gianluca E.; Bel Rafecas, Núria; Lenci, Alessandro (ACL (Association for Computational Linguistics), 2014)
    This paper empirically evaluates the performances of different state-of-the-art distributional models in a nominal lexical semantic classification task. We consider models that exploit various types of distributional ...
  • Romeo, Lauren; Mendes, Sara; Bel Rafecas, Núria (ACL (Association for Computational Linguistics), 2014)
    The work detailed in this paper describes a 2-step cascade approach for the classification of complex-type nominals. We describe an experiment that demonstrates how a cascade approach performs when the task consists in ...
  • Villegas, Marta; Bel Rafecas, Núria; Gonzalo, Carlos; Moreno, Amparo; Simelio, Nuria (ACL (Association for Computational Linguistics), 2012)
    In this paper we present two real cases, in the fields of discourse analysis of newspapers and communication research which demonstrate the impact of Language Resources (LR) and NLP in the humanities. We describe our ...
  • Del Tredici, Marco; Bel Rafecas, Núria (ACL (Association for Computational Linguistics), 2015)
    We present a method for the detection and representation of polysemous nouns, a phenomenon that has received little attention in NLP. The method is based on the exploitation of the semantic information preserved in Word ...
  • Bel Rafecas, Núria; Espeja, Sergio; Marimon, Montserrat (ACL (Association for Computational Linguistics), 2007)
    The work we present here is concerned with the acquisition of deep grammatical information for nouns in Spanish. The aim is to build a learner that can handle noise, but, more interestingly, that is able to overcome the ...
  • Necsulescu, Silvia; Mendes, Sara; Jurgens, David; Bel Rafecas, Núria; Navigli, Roberto (ACL (Association for Computational Linguistics), 2015)
    The lexical semantic relationships between word pairs are key features for many NLP tasks. Most approaches for automatically classifying related word pairs are hindered by data sparsity because of their need to observe two ...
  • Martínez Alonso, Héctor; Sandford Pedersen, Bolette; Bel Rafecas, Núria (ACL (Association for Computational Linguistics), 2011)
    The following work describes a method to automatically classify the sense selection of the complex type Location/Organization –which depends on regular polysemy– using shallow features, as well as a way to increase the ...
  • Costa Carreras, Joan (ÉLiPhi Editions de Linguistique et de Philologie, 2018)
  • Bach, Carme, 1971- (ÉLiPhi Editions de Linguistique et de Philologie, 2018)
  • Llopart, Elisabet; Loureda, Óscar; Cabré, M. Teresa (Maria Teresa), 1947-; Freixa, Judit (2014)
