    • A categorial type logic 

      Morrill, Glyn (2014)
      Article
      Accés obert
      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 ...
    • A count invariant for Lambek calculus with additives and bracket modalities 

      Valentín Fernández Gallart, José Oriol; Serret, Daniel; Morrill, Glyn (Springer-Verlag Berlin Heidelberg, 2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The count invariance of van Benthem (1991) is that for a sequent to be a theorem of the Lambek calculus, for each atom, the number of positive occurrences equals the number of negative occurrences. (The same is true ...
    • A note on movement in logical grammar 

      Morrill, Glyn (2018)
      Article
      Accés obert
      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 polynomial-time algorithm for the Lambek calculus with brackets of bounded order 

      Kanovich, Max; Kuznetsov, Stepan; Morrill, Glyn; Scedrov, Andre (Dagstuhl Publishing, 2017)
      Text en actes de congrés
      Accés obert
      Lambek calculus is a logical foundation of categorial grammar, a linguistic paradigm of grammar as logic and parsing as deduction. Pentus (2010) gave a polynomial-time algorithm for determining provability of bounded depth ...
    • A reply to Kubota and Levine on gapping 

      Valentín Fernández Gallart, José Oriol; Morrill, Glyn (2017-02)
      Article
      Accés obert
      In a series of papers Kubota and Levine give an account of gapping and determiner gapping in terms of hybrid type logical grammar, including anomalous scopal interactions with auxiliaries and negative quantifiers. We make ...
    • Categorical formalisation of relativisation : pied piping, islands, and extraction sites 

      Morrill, Glyn (1992-09-27)
      Report de recerca
      Accés obert
    • Clausal proof nets and discontinuity 

      Morrill, Glyn (1994-03)
      Report de recerca
      Accés obert
      We consider the task of theorem proving in Lambek calculi and their generalisation to "multimodal residuation calculi". These form an integral part of categorial logic, a logic of signs stemming from categorial grammar, ...
    • Computational coverage of TLG : the Montague test 

      Morrill, Glyn; Valentín Fernández Gallart, José Oriol (2015)
      Text en actes de congrés
      Accés obert
      This paper reports on the empirical coverage of Type Logical Grammar (TLG) and on how it has been computer implemented. We analyse the Montague fragment computationally and we proffer this task as a challenge to computational ...
    • Computational coverage of TLG: displacement 

      Morrill, Glyn; Valentín Fernández Gallart, José Oriol (2015)
      Text en actes de congrés
      Accés obert
      This paper reports on the coverage of TLG of Morrill (1994) and Moortgat (1997), and on how it has been computer implemented. We computer-analyse examples of displacement: discontinuous idioms, quantification, (medial) ...
    • Computational coverage of TLG: nonlinearity 

      Morrill, Glyn; Valentín Fernández Gallart, José Oriol (2015)
      Text en actes de congrés
      Accés obert
      We study nonlinear connectives (exponentials) in the context of Type Logical Grammar (TLG). We devise four conservative extensions of the displacement calculus with brackets, Db!, Db!?, Db!b and Db!b?r which contain the ...
    • Computational coverage of type logical grammar: The Montague test 

      Morrill, Glyn; Valentín Fernández Gallart, José Oriol (2016)
      Text en actes de congrés
      Accés obert
      It is nearly half a century since Montague made his contributions to the field of logical semantics. In this time, computational linguistics has taken an almost entirely statistical turn and mainstream linguistics has ...
    • Count-invariance including exponentials 

      Kuznetsov, Stepan; Morrill, Glyn; Valentín Fernández Gallart, José Oriol (Association for Computational Linguistics, 2017)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      We define infinitary count-invariance for categorial logic, extending countinvariance for multiplicatives (van Benthem, 1991) and additives and bracket modalities (Valentín et al., 2013) to include exponentials. This ...
    • Difference lists and difference bags for logic programming of categorial deduction 

      Llore, F. X.; Morrill, Glyn (1995-01-01)
      Report de recerca
      Accés obert
      We show how difference lists can be used for systematically compiled linear clauses for Lambek categorial grammar and its generalisations, in analogy with standard Horn clauses for CF grammar. We also consider use of ...
    • Discontinuity and pied-piping in categorial grammar 

      Morrill, Glyn (1993-06)
      Report de recerca
      Accés obert
      Discontinuity refers to the phenomena in many natural language constructions whereby signs differ markedly in their prosodic and semantic forms. As such it presents interesting demands on monostratal computational formalisms ...
    • Displacement logic for anaphora 

      Morrill, Glyn; Valentín Fernández Gallart, José Oriol (2014-03)
      Article
      Accés obert
      The displacement calculus of Morrill, Valentín and Fadda (2011) [25] aspires to replace the calculus of Lambek (1958) [13] as the foundation of categorial grammar by accommodating intercalation as well as concatenation ...
    • Dutch word order and binding 

      Morrill, Glyn (2000-10)
      Report de recerca
      Accés obert
      This paper offers a type-logical account of Dutch word order with special reference to quantifier binding in subordinate clauses.
    • Generalising discontinuity 

      Morrill, Glyn; Merenciano Saladrigas, Josep Maria (1996-01)
      Report de recerca
      Accés obert
      This paper makes two generalisations of categorial calculus of discontinuity. In the first we introduce unary modalities which mediate between continuous and discontinuous strings. In the second each of the modes of ...
    • Geometry of language 

      Morrill, Glyn (1997-10)
      Report de recerca
      Accés obert
      Girard (1987) introduced proof nets as a syntax of linear proofs which eliminates inessential rule ordering manifested by sequent calculus. Proof nets adapted to the Lambek calculus (Roorda 1991) fulfill a role in ...
    • Geometry of language and linguistic circuitry 

      Morrill, Glyn (2003-03)
      Report de recerca
      Accés obert
      We illustrate the potential for geometry of language and linguistic circuitry under the rendering of the syntactic structures of Lambek categorial grammar as proof nets. This empirical application sees sentences as proof ...
    • Grammar logicised: relativisation 

      Morrill, Glyn (2017-04-01)
      Article
      Accés obert
      Many variants of categorial grammar assume an underlying logic which is associative and linear. In relation to left extraction, the former property is challenged by island domains, which involve nonassociativity, and the ...
