| Abstract: | Aiming at the problems of inaccurate feature extraction and gradient explodes or gradient disappears of text information in Chinese implicit sentiment analysis by existing serialization models, a parallel hybrid model of bidirectional long short time neural network and context-aware tree recurrent neural network（CA-TRNN） is proposed. Firstly, it is used to extract the context information from the text by BiLSTM, and is extracted the semantic feature information of the target sentence in the text by the tree recurrent neural network（TRNN）. Finally, two representations are fused by the attention mechanism of the specific target sentence, and then the sentiment classification results of the text are obtained by using softmax. The experimental results in the Chinese implicit sentiment analysis task of SMP2019 micro blog show that the model CA-TRNN can effectively improve the accuracy of classification results with low time cost and better application ability. |
