"Not not bad" is not "bad": A distributional account of negation

Karl Moritz Hermann, Edward Grefenstette, Phil Blunsom

In this paper, we address shortcomings in the ability of current models to capture logical operations such as negation. We propose a tripartite formulation for acontinuous vector space representation of semantics. We then use this representation to develop a formal compositional notion of negation within such models.

Abstract

With the increasing empirical success of distributional models of compositional semantics, it is timely to consider the types of textual logic that such models are capable of capturing. In this paper, we address shortcomings in the ability of current models to capture logical operations such as negation. As a solution we propose a tripartite formulation for a continuous vector space representation of semantics and subsequently use this representation to develop a formal compositional notion of negation within such models.

Towards logical negation for compositional distributional semantics
The categorical compositional distributional model of meaning gives the composition of words into phrases and sentences pride of place. However, it has so far lacked a model of logical negation. This paper gives some steps towards providing this operator.

Challenges for Distributional Compositional Semantics
This paper summarises the current state of the art in the study of distributional semantics. We single out generalised quantifiers and intensional semantics as areas to focus attention for the development of the theory. Once suitable theories have been developed, algorithms will be needed to apply the theory to tasks.

Compositional Operators in Distributional Semantics
This survey presents in some detail the main advances that have been recently taking place in Computational Linguistics. It reviews the compositional formal semantics view and the distributional models of meaning based on vector spaces.

Don't Blame Distributional Semantics if it can't do Entailment
Distributional semantics has had enormous empirical success in Computational Linguistics and Cognitive Science. The standard answer is that distributional semantics is not fully adequate in this regard. We argue that this standard answer rests on a misconception.

Experimenting with Transitive Verbs in a DisCoCat
The categorical compositional distributional (DisCoCat) model of meaning of Coecke et al. (arXiv:1003.4394v1 [cs.CL) combines aspected of form al and distributional models. We discuss three ways of constructing such matrices,

Mathematical Foundations for a Compositional Distributional Model of Meaning
We propose a mathematical framework for a unification of the distributional and compositional theories of meaning. This mathematical framework enables us to compute the meaning of a well-typed sentence from the meanings of its constituents.
