Combination of Convolutional and Recurrent Neural Network for Sentiment Analysis of Short Texts
Sentiment analysis of short texts is challenging because of the limited contextual information they usually contain. In recent years, deep learning models such as convolutional neural networks (CNNs) and recurrent neural networks (RNNs) have been applied to text sentiment analysis with comparatively remarkable results. In this paper, we describe a jointed CNN and RNN architecture, taking advantage of the coarse grained local features generated by CNN and long distance dependencies learned via RNN for sentiment analysis of short texts. Experimental results show an obvious improvement upon the state of the art on three benchmark corpora, MR, SST1 and SST2, with 82.28% 51.50% and 89.95% accuracy, respectively.
