Extraction in the Lambek-Grishin Calculus [PDF]

open access: yes, 2010
We propose an analysis of extraction in the Lambek-Grishin calculus (LG): a categorial type logic featuring subtractions, with proof-theoretic behavior dual to that of the usual implications. Our analysis rests on three pillars: Moortgat’s discontinuous type constructors; their decomposition in LG as proposed by Bernardi and Moortgat; and the polarity ...

Mathematical Foundations for a Compositional Distributional Model of Meaning [PDF]

open access: yes, 2010
We propose a mathematical framework for a unification of the distributional theory of meaning in terms of vector space models, and a compositional theory for grammatical types, for which we rely on the algebra of Pregroups, introduced by Lambek.

Lambek calculus is NP-complete

open access: yesTheoretical Computer Science, 2006
The main goal of the paper is to show that the derivability problems for the Lambek calculus (L) and for the Lambek calculus allowing empty premises (L*) are NP-complete. The construction of a reduction from the problem CSAT to the L-derivability and L*-derivability problems is described, and the correctness of this reduction is proved.

Higher-order Linear Logic Programming of Categorial Deduction

open access: yes, 1994
We show how categorial deduction can be implemented in higher-order (linear) logic programming, thereby realising parsing as deduction for the associative and non-associative Lambek calculi.

A Generalised Quantifier Theory of Natural Language in Categorical Compositional Distributional Semantics with Bialgebras [PDF]

open access: yes, 2016
Categorical compositional distributional semantics is a model of natural language; it combines the statistical vector space models of words with the compositional models of grammar.

Context Update for Lambdas and Vectors [PDF]

open access: yes, 2016
Vector models of language are based on the contextual aspects of words and how they co-occur in text. Truth conditional models focus on the logical aspects of language, the denotations of phrases, and their compositional ...

Lexical and Derivational Meaning in Vector-Based Models of Relativisation

open access: yes, 2017
Sadrzadeh et al (2013) present a compositional distributional analysis of relative clauses in English in terms of the Frobenius algebraic structure of finite dimensional vector spaces.
