论文摘要
通过使信息的生产和复制民主化的技术，社交媒体中每日互动的很大一部分被谣言感染了。尽管对谣言检测和验证进行了广泛的研究，但到目前为止，尚未考虑计算谣言传播力量的问题。为了解决这一研究差距，本研究寻求一个模型来计算谣言（SPR）作为基于内容特征的功能两类的功能：虚假谣言（FR）和真实谣言（TR）。为此，将采用Allport和Postman的理论，它声称重要性和歧义是谣言和谣言的力量中的关键变量。引入了两个类别的“重要性”（28个功能）和“歧义”（14个功能）的42个内容功能以计算SPR。在两个数据集（Twitter和Telegram）上评估了所提出的模型。结果表明，（i）虚假谣言文件的传播力量很少超过真正的谣言。 （ii）两组虚假谣言和真实谣言的SPR平均值之间存在显着差异。 （iii）SPR作为标准可以对区分虚假谣言和真实谣言产生积极影响。
With technologies that have democratized the production and reproduction of information, a significant portion of daily interacted posts in social media has been infected by rumors. Despite the extensive research on rumor detection and verification, so far, the problem of calculating the spread power of rumors has not been considered. To address this research gap, the present study seeks a model to calculate the Spread Power of Rumor (SPR) as the function of content-based features in two categories: False Rumor (FR) and True Rumor (TR). For this purpose, the theory of Allport and Postman will be adopted, which it claims that importance and ambiguity are the key variables in rumor-mongering and the power of rumor. Totally 42 content features in two categories "importance" (28 features) and "ambiguity" (14 features) are introduced to compute SPR. The proposed model is evaluated on two datasets, Twitter and Telegram. The results showed that (i) the spread power of False Rumor documents is rarely more than True Rumors. (ii) there is a significant difference between the SPR means of two groups False Rumor and True Rumor. (iii) SPR as a criterion can have a positive impact on distinguishing False Rumors and True Rumors.
