A lexicographic encoding for word sense disambiguation with evolutionary neural networks

Abstract

We propose a supervised approach to word sense disambiguation based on neural networks combined with evolutionary algorithms. Large tagged datasets for every sense of a polysemous word are considered, and used to evolve an optimized neural network that correctly disambiguates the sense of the given word considering the context in which it occurs. A new distributed scheme based on a lexicographic encoding to represent the context in which a particular word occurs is proposed. The viability of the approach has been demonstrated through experiments carried out on a representative set of polysemous words. © Springer-Verlag 2009.
