Abstract

'Fake news' refers to the misinformation presented about issues or events, such as COVID-19. Meanwhile, social media giants claimed to take COVID-19 related misinformation seriously, however, they have been ineffectual. This research uses Information Fusion to obtain real news data from News Broadcasting, Health, and Government websites, while fake news data are collected from social media sites. 39 features were created from multimedia texts and used to detect fake news regarding COVID-19 using state-of-the-art deep learning models. Our model's fake news feature extraction improved accuracy from 59.20% to 86.12%. Overall high precision is 85% using the Recurrent Neural Network (RNN) model; our best recall and F1-Measure for fake news were 83% using the Gated Recurrent Units (GRU) model. Similarly, precision, recall, and F1-Measure for real news are 88%, 90%, and 88% using the GRU, RNN, and Long short-term memory (LSTM) model, respectively. Our model outperformed standard machine learning algorithms.

摘要

“假新闻”指的是关于各种问题或事件(如新冠疫情)所呈现的错误信息。与此同时,社交媒体巨头声称严肃对待与新冠疫情相关的错误信息,然而,他们并未取得成效。本研究运用信息融合从新闻广播、健康及政府网站获取真实新闻数据,而假新闻数据则从社交媒体网站收集。从多媒体文本中创建了39个特征,并使用最先进的深度学习模型来检测有关新冠疫情的假新闻。我们模型的假新闻特征提取将准确率从59.20%提高到了86.12%。使用循环神经网络(RNN)模型时,总体高精度为85%;使用门控循环单元(GRU)模型时,我们针对假新闻的最佳召回率和F1值为83%。同样,使用GRU、RNN和长短期记忆(LSTM)模型时,真实新闻的精确率、召回率和F1值分别为88%、90%和88%。我们的模型优于标准机器学习算法。
