Abstract

In order to effectively identify the sentiment polarity of Chinese microblogs, based on the cognitive fact that emojis can change or enhance the sentiment polarity of the texts, this paper proposed an emoji attentional neural network model for microblog sentiment analysis. This model firstly used a Bi-LSTM model to learn the feature representation of the text, and then implemented an emoji-based attention mechanism to obtain a new feature representation after combining text with the emojis, so as to recognize the sentiment polarity of the microblogs. The experiments show that compared with the Bi-LSTM model that inputs plain text and emojis, the accuracy rate of the emoji-attentional model is increased by 4.06%; compared with the Bi-LSTM model that only inputs plain text, the accuracy rate of emoji-attentional model is increased by 6.35%.
