  In this work, we present an effective method for semantic specialization of
word vector representations. To this end, we use traditional word embeddings
and apply specialization methods to better capture semantic relations between
words. In our approach, we leverage external knowledge from rich lexical
resources such as BabelNet. We also show that our proposed post-specialization
method based on an adversarial neural network with the Wasserstein distance
allows to gain improvements over state-of-the-art methods on two tasks: word
similarity and dialog state tracking.
