复杂网络中信息扭曲的仿真研究

摘要在实际生活中由于个体认知能力的有限性以及环境所能提供信息的有限性导致了个体对信息认知处理的扭曲性结果。现有研究鲜有将个体信息扭曲行为放置在一个复杂网络情境中，因此本文旨在将信息扭曲以及复杂网络两个区域的研究成果结合起来，从经典的信息认知处理和信息扭曲的研究中挖掘个体的行为决策机制，将这些决策机制分为“位模式” 决策规则、“标准模式”决策规则和“随机模式”决策规则探讨其对信息的扭曲程度，在一个动态的时空域上观测社会化信息传播或意见演化的过程和效应。75318

实验结果表明，个体的记忆力对信息的扭曲没有明显的影响，传播信息的人数越多，信息扭曲度越低，通过比对所有接收信息同的那部分内容在所有接收信息中的出现频次，并最终选择频次高的作为可信内容的“位模式”决策规则对信息的扭曲程度最低。目前由于手机和网络的迅速发展，各个决策者之间的沟通也变得更加密切，这使得决策者可参照的信息越来越多，从而能更好地帮助决策者做出正确的决策。

Title Simulation of information distortion in complex networks

Abstract In real life, due to the limited cognitive ability is limited and the environment can provide information on the inpidual leads to distortion of information cognitive processing。 Existing studies are not inpidual information distortions placed in a complex network environment, this paper aims to research the information distortion and the complex network of two areas combined mining behavior decision mechanism of inpidual from the classical studies of cognitive information processing and information distortion, the decision-making mechanism is pided into Bit-wise mode, Standard mode and Random mode to investigate the degree of distortion of information, process and effect of social information dissemination or opinion evolution in time-space domain on a dynamic observation。

Experimental results show that the inpidual memory distortion of information, there is no obvious effect, the more the number of information dissemination, information distortion degree is low, by comparison all information received in common the part in all received information in frequency, and ultimately selected frequency high as mode Bit-wise trusted content of information distortion degree minimum。 At present due to the rapid development of mobile phones and the Internet, communication between each decision maker has become more closely, which makes the decision maker can refer to the information more and more, so that it can better help the decision makers to make the right decision。
