Modelling Lexical Ambiguity with Density Matrices

Francois Meyer, Martha Lewis

Words can have multiple senses. Compositional distributional models of meaning have been argued to deal well with finer shades of meaning variation known as polysemy, but are not s…

Cats climb entails mammals move: preserving hyponymy in compositional distributional semantics

Gemma De las Cuevas, Andreas Klingler, Martha Lewis +1

To give vector-based representations of meaning more structure, one approach is to use positive semidefinite (psd) matrices. These allow us to model similarity of words as well as…

Towards logical negation for compositional distributional semantics

Martha Lewis

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 log…

Compositionality for Recursive Neural Networks

Martha Lewis

Modelling compositionality has been a longstanding area of research in the field of vector space semantics. The categorical approach to compositionality maps grammar onto vector sp…

Translating and Evolving: Towards a Model of Language Change in DisCoCat

Tai-Danae Bradley, Martha Lewis, Jade Master +1

The categorical compositional distributional (DisCoCat) model of meaning developed by Coecke et al. (2010) has been successful in modeling various aspects of meaning. However, it f…

Internal Wiring of Cartesian Verbs and Prepositions

Bob Coecke, Martha Lewis, Dan Marsden

Categorical compositional distributional semantics (CCDS) allows one to compute the meaning of phrases and sentences from the meaning of their constituent words. A type-structure c…
