Participación de SINAI en TASS 2016

This paper introduces the polarity classification system used by the SI-NAI team for the task 1 at the TASS 2016 workshop. Our approach is based on a supervised learning algorithm over vectors resulting from a weighted vector. This vector is computed using a deep-learning algorithm called Word2Vec. The algorithm is applied so as to generate a word vector from a deep neural net trained over a specific tweets collection and the Spanish Wikipedia. Our experiments show massive data from Twitter can lead to a slight improvement in classificaciones accuracy. el apartado 4 se describe el sistema desarro
