    • A categorial type logic 

      Morrill, Glyn (2014)
      Article
      Open Access
      In logical categorial grammar [23,11] syntactic structures are categorial proofs and semantic structures are intuitionistic proofs, and the syntax-semantics interface comprises a homomorphism from syntactic proofs to ...

      Article
      Open Access
      In a recent article, Christiansen and Chater (2016) present a fundamental constraint on language, i.e. a now-or-never bottleneck that arises from our fleeting memory, and explore its implications, e.g., chunk-and-pass ...

    • A note on movement in logical grammar 

      Morrill, Glyn (2018)
      Article
      Open Access
      In this article, we make some brief remarks on overt and covert movement in logical grammar. With respect to covert movement (e.g. quantification), we observe how a treatment in terms of displacement calculus interacts ...
    • A second-order joint Eisner model for syntactic and semantic dependency parsing 

      Lluis Martorell, Xavier; Bott, Stefan Markus; Màrquez Villodre, Lluís (2009)
      Conference lecture
      Restricted access - publisher's policy
      We present a system developed for the CoNLL-2009 Shared Task (Hajic et al., 2009). We extend the Carreras (2007) parser to jointly annotate syntactic and semantic dependencies. This state-of-the-art parser factorizes the ...
    • A stronger null hypothesis for crossing dependencies 

      Ferrer Cancho, Ramon (2014-12-04)
      Article
      Open Access
      The syntactic structure of a sentence can be modeled as a tree where vertices are words and edges indicate syntactic dependencies between words. It is well known that those edges normally do not cross when drawn over the ...
    • ADN-classifier: automatically assigning denotation types to nominalizations 

      Peris, Aina; Taulé, Mariona; Boleda Torrent, Gemma; Rodríguez Hontoria, Horacio (2010)
      Conference report
      Open Access
      This paper presents the ADN-Classifier, an Automatic classification system of Spanish Deverbal Nominalizations aimed at identifying its semantic denotation (i.e. event, result, underspecified, or lexicalized). The classifier ...
    • AETAS: A system for semanticizing temporal expressions from unstructured contents 

      Ardalan, Zagros; Martín Escofet, Carme; Padró, Lluís (Springer, 2015)
      Conference report
      Restricted access - publisher's policy
      AETAS is an online tool for converting text into RDF linked data with resolution of temporal expressions. AETAS follows fully SOA architecture and is accessible via web-service. It implements a novel approach for semantic ...
    • An agent-based model of the emergence and evolution of a language system for boolean coordination 

      Sierra Santibáñez, Josefina (2018-03-19)
      Article
      Open Access
      This paper presents an agent-based model of the emergence and evolution of a language system for Boolean coordination. The model assumes the agents have cognitive capacities for invention, adoption, abstraction, repair ...
    • An agent-based model of the emergence and evolution of a language system for boolean coordination 

      Sierra Santibáñez, Josefina (International Foundation for Autonomous Agents and Multiagent Systems (IFAAMAS), 2019)
      Conference report
      Restricted access - publisher's policy
      This paper presents an agent-based model for studying the emergence and evolution of a language system for Boolean coordination. The model has been implemented and tested by conducting a series of experiments that show ...
    • An agent-based model of the emergence and transmission of a language system for the expression of logical combinations 

      Sierra Santibáñez, Josefina (AAAI Press (Association for the Advancement of Artificial Intelligence), 2015)
      Conference report
      Restricted access - publisher's policy
      This paper presents an agent-based model of the emergence and transmission of a language system for the expression of logical combinations of propositions. The model assumes the agents have some cognitive capacities for ...
    • An agent-based model studying the acquisition of a language system of logical constructions 

      Sierra Santibáñez, Josefina (AAAI Press. Association for the Advancement of Artificial Intelligence, 2014)
      Conference report
      Open Access
      This paper presents an agent-based model that studies the emergence and evolution of a language system of logical constructions, i.e. a vocabulary and a set of grammatical constructions that allows the expression of logical ...
    • An empirical study of semi-supervised structured conditional models for dependency parsing 

      Suzuki, Jun; Isozaki, Hideki; Carreras Pérez, Xavier; Collins, Michael (2009)
      Conference report

      Article
      Open Access
      The syntactic structure of a sentence can be modelled as a tree, where vertices correspond to words and edges indicate syntactic dependencies. It has been claimed recurrently that the number of edge crossings in real ...
