基于卷积神经网络和用户信息的微博话题追踪模型

摘要

为了解决微博文本特征抽取及特征稀疏问题,提出基于卷积神经网络的微博话题追踪模型(CNN-TTM).基于微博用户信息,又提出融合微博用户信息及卷积神经网络的微博话题追踪模型(CNN-UserTTM),利用微博用户信息提高话题追踪准确率.实验表明,在新浪微博数据集上,CNN-TTM和CNN-UserTTM分别获得较高的微博话题追踪准确率.%Aiming at feature sparseness and feature extraction of microblog text, a topic tracking model for Chinese microblog based on convolutional neural network(CNN-TTM) is proposed. Furthermore, user profiles and attributes are incorporated into CNN-TTM and a model called CNN-UserTTM is constructed. The user information of microblog is used to improve the accuracy of topic tracking. The experimental results demonstrate that CNN-TTM and CNN-UserTTM reach a high accuracy respectively on Sina microblog dataset.
