On social media platforms, hot topics often contain several pieces of related information that can influence internet users, generating either positive or negative opinion orientation. Some of them will choose to retain or change their original opinions after exposure to multiple related messages. To describe the opinion-transfer transient and collective behaviors in this scenario, this paper proposes an opinion-transfer susceptible-forwarding-immunized (OT-SFI) information cross-propagation model. Real multiple information in messages with opinions obtained from the Chinese Sina microblog is used for data fitting to illustrate how model parameters can be estimated and used to predict the accumulative numbers of users with a particular view. The study attempts to relate changes in group views in the network to initial opinion distribution and individuals' opinion choices at the macro level. Furthermore, the model parameters at the micro level are used to measure the probability of "retention" and "reversal" of views in events, as well as the extent to which the masses are influenced by new information views. The result illustrates that the viewpoint distribution of the initial message and the opinion selection of the new message opinion leaders play crucial roles in promoting attention to the topic and driving for a desired collective opinion.
在社交媒体平台上,热门话题通常包含几条相关信息,这些信息会影响互联网用户,产生积极或消极的舆论导向。其中一些人在接触到多条相关信息后会选择保留或改变他们原来的观点。为了描述这种情况下的观点转移瞬态和集体行为,本文提出了一种观点转移易感-转发-免疫(OT-SFI)信息交叉传播模型。利用从中国新浪微博获得的带有观点的真实多条信息进行数据拟合,以说明如何估计模型参数并用于预测具有特定观点的用户累积数量。该研究试图在宏观层面将网络中群体观点的变化与初始观点分布和个体的观点选择联系起来。此外,微观层面的模型参数用于衡量事件中观点“保留”和“反转”的概率,以及大众受新信息观点影响的程度。结果表明,初始信息的观点分布和新信息意见领袖的观点选择在促进对话题的关注和推动形成期望的集体意见方面起着关键作用。
