Recent Submissions

  • Sorodoc, Ionut-Teodor; Pezzelle, Sandro; Bernardi, Raffaella (ACL (Association for Computational Linguistics), 2018)
    The present work investigates whether different quantification mechanisms (set comparison, vague quantification, and proportional estimation) can be jointly learned from visual scenes by a multi-task computational model. ...
  • Boleda, Gemma; Aina, Laura; Silberer, Carina; Sorodoc, Ionut-Teodor; Westera, Matthijs (ACL (Association for Computational Linguistics), 2019)
    Humans use language to refer to entities in the external world. Motivated by this, in recent years several models that incorporate a bias towards learning entity representations have been proposed. Such entity-centric ...
  • Boleda, Gemma; Del Tredici, Marco; Fernández, Raquel (ACL (Association for Computational Linguistics), 2019)
    We present the first exploration of meaning shift over short periods of time in online communities using distributional representations. We create a small annotated dataset and use it to assess the performance of a standard ...
  • Boleda, Gemma; Gulordava, Kristina; Aina, Laura (ACL (Association for Computational Linguistics), 2019)
    In neural network models of language, words are commonly represented using context invariant representations (word embeddings) which are then put in context in the hidden layers. Since words are often ambiguous, representing ...
  • Westera, Matthijs (ACL (Association for Computational Linguistics), 2019)
    Distributional semantics has had enormous empirical success in Computational Linguistics and Cognitive Science in modeling various semantic phenomena, such as semantic similarity, and distributional models are widely used ...
  • Wentland, Wolodja; Silberer, Carina; Hartung, Matthias (ELRA (European Language Resources Association), 2008)
    In this paper, we present HeiNER, the multilingual Heidelberg Named Entity Resource. HeiNER contains 1,547,586 disambiguated English Named Entities together with translations and transliterations to 15 languages. Our work ...
  • Silberer, Carina; Ponzetto, Simone Paolo (ACL (Association for Computational Linguistics), 2010)
    We describe the University of Heidelberg (UHD) system for the Cross-LingualWord Sense Disambiguation SemEval-2010 task (CL-WSD). The system performs CLWSD by applying graph algorithms previously developed for monolingual ...
  • Silberer, Carina; Lapata, Mirella (ACL (Association for Computational Linguistics), 2012)
    A popular tradition of studying semantic representation has been driven by the assumption that word meaning can be learned from the linguistic environment, despite ample evidence suggesting that language is grounded in ...
  • Silberer, Carina; Frank, Anette (ACL (Association for Computational Linguistics), 2012)
    Linking implicit semantic roles is a challenging problem in discourse processing. Unlike prior work inspired by SRL, we cast this problem as an anaphora resolution task and embed it in an entity-based coreference ...
  • Silberer, Carina; Ferrari, Vittorio; Lapata, Mirella (ACL (Association for Computational Linguistics), 2013)
    We consider the problem of grounding the meaning of words in the physical world and focus on the visual modality which we represent by visual attributes. We create a new large-scale taxonomy of visual attributes covering ...
  • Grimm, Scott; McNally, Louise, 1965- (Cascadilla Proceedings Project, 2016)
  • Boleda, Gemma; Vecchi, Eva Maria; Cornudella Gaya, Miquel; McNally, Louise, 1965- (ACL (Association for Computational Linguistics), 2012)
    Adjectival modification, particularly by expressions that have been treated as higher-order modifiers in the formal semantics tradition, raises interesting challenges for semantic composition in distributional semantic ...
  • Aina, Laura; Bernardi, Raffaella; Fernández, Raquel (CEUR Workshop Proceedings, 2018)
    In this paper, we investigate the relation between negated adjectives and antonyms in English using Distributional Semantics methods. Results show that, on the basis of contexts of use, a negated adjective (e.g., not cold) ...
  • Boleda, Gemma; Baroni, Marco; Pham, Nghia The; McNally, Louise, 1965- (ACL (Association for Computational Linguistics), 2013)
    Distributional semantics has very successfully modeled semantic phenomena at the word level, and recently interest has grown in extending it to capture the meaning of phrases via semantic composition. We present experiments ...
  • 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 ...
