为帮助公众识别假新闻,研究使用人工智能和高级统计技术检测假新闻,在此基础上探讨开发学生媒体素养的评估和学习工具。通过人工智能、计算语言学和高级统计,分析用户或推特属性是否能区分4165条纠正过拼写错误的英文推文的真、假新闻,这些推文与20条匹配的相关新闻报道之一(10条真,10条假)关联。相较而言,使用常用词、负面情绪、更高情感激励、更高支配力、第一人称单数代词、第三人称代词或拥有更多关注用户的推文,是真新闻的可能性更大;使用第二人称代词、以无主语句开头或使用委婉语的推文,是假新闻的可能性更大。结果表明,一些通用的预测因素(如代词、礼貌用语、关注用户人数等)和特定主题的预测因素(如常用词、情绪、委婉语等)可以有效识别真假新闻。最后提出用简单易懂的媒体素养仪表盘模拟假新闻的传播范围、速度和形状,以帮助学生学习和评估自身媒体素养。
