Geometry of Semantic Space: Comparative Study of Discrete and Continuous Models
Gabriel Bounias, Sabine Ploux
This work examines the semantic geometry underlying NLP models. We compare supervised vector embeddings, such as CamemBERT, with lexical co-occurrence graphs that encode semantic r…

Organization and Independence or Interdependence? Study of the Neurophysiological Dynamics of Syntactic and Semantic Processing
Sabine Ploux, Viviane Déprez
In this article we present a multivariate model for determining the different syntactic, semantic, and form (surface-structure) processes underlying the comprehension of simple phr…

Random vector generation of a semantic space
Jean-François Delpech, Sabine Ploux
We show how random vectors and random projection can be implemented in the usual vector space model to construct a Euclidean semantic space from a French synonym dictionary. We eva…
