摘要： 针对一种信息特征进行检测方法在信息传播早期阶段提取的特征信息往往不充分,导致传播早期阶段检测准确率较低的问题,提出一个新颖的混合深度模型EGSI,模型由EXTRACT、GRU、SCORE和INTERATE 4个模块组成。EXTRACT通过卷积神经网络提取信息的传播路径特征,GRU通过门控循环单元捕获信息的文本特征和反馈特征,SCORE基于用户行为挖掘用户特征,INRERATE整合以上特征并预测出信息事件类标。EGSI通过整合信息最基本的4种特征(文本、用户、反馈、传播路径),从而可以在信息传播的早期阶段充分提取可用特征信息,进而较准确地检测出虚假信息。真实数据集的试验结果表明,模型在信息传播60 min内的准确率达到95.9%。相比基准方法,EGSI模型在检测虚假信息的准确率和时效性之间取得了较好的平衡。
