Abstract: In view of the classification of emotional tendency in the short text comments on consumption, a BSP-CNN hybrid neural network model is proposed. The model first uses the Bidirectional Simple Recurrent Unit（BiSRU） to characterize the data, then uses Point-by-point Convolutional Neural Network（P-CNN） to further learn semantic features and output the results of emotional tendency classification. Experimental results show that compared with traditional Long Short-Term Memory neural networks（LSTM） and Convolutional Neural Networks（CNN）, the BSP-CNN hybrid neural network model effectively simplifies calculation, shortens the running time, and obtains higher F1 socre on data sets of different sizes and text lengths.

摘要： 针对消费短文本评论中的情感倾向性分类问题，提出了一种BSP-CNN混合神经网络模型。模型先使用双向简单循环单元（BiSRU）对数据进行特征表示，再使用逐点卷积神经网络（P-CNN）进一步学习语义特征，并输出情感倾向性分类结果。实验结果表明，与传统的长短期记忆神经网络（LSTM）和卷积神经网络（CNN）相比，BSP-CNN混合神经网络模型有效简化了计算，缩短了运行时间，并且在不同大小和不同文本长度的数据集上均能取得更高的F1值。
