Abstract

Micro-blog sentiment analysis aims to study the emotional views of users on hot events, and research shows that deep learning is feasible in micro-blog's sentiment analysis. In view of traditional convolutional neural network, micro-blog sentiment analysis ignores the correlation between discontinuous words. Therefore, this paper applied attention mechanism to the input end of convolutional neural network(CNN) model to improve this problem. Because Chinese micro-blog belongs to the short text category, there was a possibility of losing too many semantic features in the selection of pooling layer features in the process of convolutional neural network forward propagation, so into the long short term memory neural network tree at the output of the convolutional neural network terminal(LSTM), by adding the sentence structure to strengthen the deep semantic learning. Based on the two improvements, it constructed a Chinese micro-blog sentiment analysis model(Att-CTL). Experiments show that the model has excellent characteristics in Chinese micro-blog sentiment analysis, especially in polarity shifting, and maintains a high F1 value.
