基于字词向量的多尺度卷积神经网络微博评论的情感分类模型及实验研究

A Sentiment Classification Model and Experimental Study of Microblog Commentary Based on Multivariate Convolutional Neural Networks Based on Word Vector

[目的/意义]微博评论情感分类模型可以为相关舆情监管部门正确管控话题事件的发展状况和舆情提供一定的指导作用。[方法/过程]基于字词向量的多尺度卷积神经网络,运用多尺度卷积核改善微博评论中上下文信息有限的条件制约,构建基于字词向量的多尺度卷积神经网络微博评论情感分类模型;通过爬取“微博热搜整改”数据,对模型的可行性和优越性进行验证。[结果/结论]验证结果表明基于字词向量的多尺度卷积神经网络在微博舆情等上下文信息有限的短文本分类任务中表现良好。本文在理论层面为微博舆情情感分类提供了更为准确的情感分类理论模型及分类方法,在实践层面可以更好地指导舆情监管部门对舆情的情感倾向进行更好的引导和监管。

[Purpose/significance]The microblog commentary sentiment classification model can play a guiding role for the relevant public opinion supervision departments to correctly control the development of the topic events and the public opinion.[Method/process]Based on the multi-scale convolutional neural network of word vector,this paper used multi-scale convolution kernel to improve the conditional constraints of finite context information in microblog commentary,and constructed multi-scale convolutional neural network microblog commentary emotion classification model based on word vector.Finally,the feasibility and superiority of the model were verified by crawling the real data of“microblogging hot search and rectification”.[Result/conclusion]Verification results show that the multi-scale convolutional neural network based on word vector performs well in the short text classification task with limited context information such as weibo public opinion.On the theoretical level,this paper provides a more accurate emotional classification theory model and classification method for microblogging public opinion emotion classification.In practice,it can better guide the public opinion supervision department to better guide and supervise the emotional sentiment of public opinion.
