Sentiment Classification Based on Double Attention Convolutional Neural Network Model
Convolutional Neural Networks (CNN) cannot discriminate the correlation between feature words and emotions in the input text. Therefore
this paper proposes a double attention mechanism convolutional neural network to incorporate word and POS(Part-of-speech Tagging) information into sentiment classification (Double Attention Convolutional Neural Networks
DACNN)
which combines the word features with the part-of-speech features to obtain the feature representation of the text and determine the sentiment tendency. In this paper
we introduce an attention convolutional neural network to incorporate word and POS information into sentiment classification. The first local attention mechanism captures local feature from word and POS channels. And then we propose a novel architect for combining two features by a global attention mechanism
which can decide how much information to use from word or POS information. The model is validated on MR and SST-1 datasets
achieving 0.7% and 1% improvement in accuracy compared to conventional convolutional neural networks and traditional machine learning methods.
