摘　　要：随着各类社交媒体上的评论数据数量的急剧增加,从大量的评论数据中挖掘出其所包含的情感信息具有越来越高的商业价值。本文提出了一种基于卷积神经网络的社交媒体情感分类模型,首先通过包含酒店评论在内的语料库完成词向量的初始化,而后通过卷积网络层、隐含层、嵌入层和分类层完成评论数据的情感分类。实验结果表明,基于卷积神经网络的情感分类模型无论是面对不同维度的词向量模型还是不同比例的测试集,都能够得到较高的分类准确率。With the number of comments on all kinds of social media increased dramatically,it has higher and higher commercial value while mining emotional information contained in a large number of comments. This article puts forward a social media sentiment classification model based on convolutional neural network. It at first finishes the word vector initialization through a corpus of hotel reviews,and then realizes the sentiment classification through convolutional network layer,hidden layer,embed layer and classification layer. Experiment results show that the emotion classification model based on convolutional neural network can get higher classification accuracy in terms of different dimension word vector models or in different proportion of test sets.
