| 摘 要： | 深度神经网络模型通常使用注意力机制或融合卷积神经网络来提取特征，但由于注意力机制抓取的特征过于单一，存在提取特征不完善的问题。 将循环机制引入卷积神经网络中，构建了具有双循环结构的网络模型(DRCNN)，从而改善模型的特征提取能力，将其与双向长短期记忆网络结合，提出一种带有注意力机制、特征提取能力更强的混合模型(BiLSTM-DRCNN)并应用于情感分类任务中。通过情感分类的实验分析表明，BiLSTM-DRCNN 神经网络模型具有比较好的性能，与融合卷积神经网络(CNN)和双循环长短期记忆神经网络(BiLSTM)模型相比，综合评价指标提高2%以上；与BiLSTM-CNN、Fusion Model 模型相比，综合评价指标提高了近1%，且收敛速度更快。

| Abstract: | Deep neural network models usually use attention mechanism or fusion convolutional neural network for feature extraction. However, due to the fact that the features grasped by the attention mechanism are too simplified, there is a problem that the extraction features are not perfect. Therefore, the recurrent mechanism was introduced into the convolutional neural network, and a double recurrent convolutional neural network model was constructed to improve the feature extraction ability of the model. Then the model was combined with the bidirectional long and short-term memory network, so as to put forward a hybrid model with the attention mechanism and stronger feature extraction capability (BiLSTM-CNN), which was applied to sentiment classification tasks. Experimental analysis of sentiment classification shows that the BiLSTM-DRCNN neural network model has good performance, and the comprehensive evaluation index is increased by more than 2% compared with the fusion convolutional neural network (CNN) and the double-loop long short-term memory neural network (BiLSTM) model. Compared with the BiLSTM-CNN and Fusion Model models, the comprehensive evaluation index is improved by nearly 1%, and the convergence is faster. |
