开放互联网环境基于信息熵的信息传播影响力计算方法

Calculation method of information dissemination based on information entropy in public internet

研究了开放互联网环境下衡量信息传播的影响力,提出了一种基于最大熵理论的信息传播影响力计算方法。首先,对信息传播影响力所涉及的要素进行建模;然后,以香农信息熵理论为基础,根据“奥卡姆剃刀原理”选取信息影响力关联指标;最后,基于信息熵理论给出了信息传播影响力的计算方法。对学术论文引文和网络舆情事件的传播影响力进行了分析,验证了所提方法的有效性,所提方法对探究信息在开放互联网环境中的传播影响力以及对受众的影响程度具有重要的现实意义。

A method of how to calculate the influence of information dissemination based on the maximum entropy theory was presented,which aimed at evaluating the impacts of the information dissemination in the open internet environment.Firstly,the influential factors of the information dissemination were analyzed.Then,the factors that have high correlation with the calculation of information dissemination were selected by the principle of“Occam’s Razor”,based on Shannon's information entropy theory.Finally,the method of computing the influence of information dissemination was proposed based on the information entropy theory.The effectiveness of the proposed method was validated by the experiments of analyzing the influence of the information dissemination of academic paper citations and hot public opinion events.The experiments show that the proposed method is of great significance for investigating the influence of information dissemination and the extent of impacts on the audience as well as the trends of information evolution in the open internet environment.
