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, modelling it as a version of projection onto the
subspace orthogonal to a word. We give a small demonstration of the operators
