中文摘要: 情感倾向性分类是自然语言处理领域中的热门话题,它的一个重要应用是挖掘线上评论中的重要信息,掌握网络舆论走向,因此本文提出一种基于GDBN网络的文本情感倾向性分类算法.该算法通过引入遗传算法来改进深度置信网络模型中的隐层,使模型自行对隐单元个数寻优,取得当前模型的适宜值,并以此模型进行深层建模与特征提取.最后通过反向传播网络对提取到的特征进行情感倾向性分类.在多个文本数据集上进行实验验证,验证结果表明了本文算法的有效性.
Abstract:Text sentiment classification is a hot topic in the field of natural language processing. One of its important applications is to dig out important information from online comments and grasp the trend of public opinion on the Internet. Therefore, this study proposes a method of text sentiment classification based on GDBN neural network. The algorithm improves the hidden layer in the DBN neural network by introducing genetic algorithm, which is of powerful global searching ability, and the algorithm optimizes the number of hidden units and obtains the appropriate value of the current model, then the modeling and feature extraction of this model. Finally, we can classify the extracted features of the BP neural network. By testing multiple data, the results show that the proposed algorithm is effective.
