Learning to Negate Adjectives with Bilinear Models

Abstract

We learn a mapping that negates adjectives by predicting an adjective's antonym in an arbitrary word embedding model. We show that both linear models and neural networks improve on this task when they have access to a vector representing the semantic domain of the input word, e.g. a centroid of temperature words when predicting the antonym of `cold'. We introduce a continuous class-conditional bilinear neural network which is able to negate adjectives with high precision.
