Cícero dos Santos · 2014
In this paper we describe a Deep Convolutional Neural Network (DNN) approach to perform two sentiment detection tasks: message polarity classification and contextual polarity disambiguation.We apply the proposed approach for the SemEval-2014 Task 9: Sentiment Analysis in Twitter.Despite not using any handcrafted feature or sentiment lexicons, our system achieves very competitive results for Twitter data.
