社交媒体中信息可靠性测评研究——以微博为例

The Reliability Evaluation on Information in Social Media——A Case of Micro Blog

通过问卷调查从信息接收者、信息发布者、信息传播途径和信息本身4个方面构建了社交媒体中信息可靠性测评的指标体系。根据社交媒体中信息可靠性测评指标的模糊性构建了基于三角模糊数的社交媒体中信息可靠性测评模型,利用模糊一致偏好关系确定评价指标权重。以微博为例详细阐述了社交媒体中信息可靠性测评的流程。将理论研究和实际应用有效结合起来,有利于提高社交媒体中信息可靠性判断的准确性。

From the receivers, information publishers, information transmission and information itself, it constructs index system for reliability evaluation of information in social media. According to the ambiguity of information transformed in social me- dia, it presented a new reliability evaluation model based on triangular fuzzy number. Fuzzy consistent preference relations are ap- plied to determine the weight of each index. MicroBlog is selected as a typical case to elaborate the process of reliability evaluation of information within it. The Combination between theoretical study and practical application is benefit for users of social media to improve judging accuracy of the reliability of information transformed within social media.
