【摘要】 为提高对网络短文本分类的性能,提出一种融合卷积神经网络(CNN)和句子级监督学习的分类方法。构建一种用于短文本分类的经典CNN模型;将主题句融入到CNN中,即对输入文本进行句子级CNN监督学习,构建句子模型并识别主题句;将主题句子模型赋予较高权重,通过加权和构建文本模型。通过文本级CNN监督学习,实现文本分类。在两个评论数据集上的实验结果表明,提出方法具有较高的分类准确性。更多还原

【Abstract】 To improve the performance of network short text classification,a fusion method of convolution neural network(CNN)and sentence-level supervised learning was proposed.A classic CNN model was built for short text classification.The subject sentence was integrated into the CNN,the sentence-level CNN supervised learning for the input text was executed,and sentence model was built and the subject sentence was identified.The subject sentence model was given a higher weight,and the text model was constructed by weighting.Text classification was achieved through text-level CNN supervised learning.Experimental results on the two review datasets show that the proposed method has high classification accuracy.更多还原
