摘要
使用multi-Agent的建模思想,以现实为基础建立了一个舆论涌现的仿真模型.该模型主要由个体和媒体以及它们之间的规则组成.个体的属性包括了个体之间的信任度、个体观点的可信度和个体的从众性;媒体的属性包括媒体的影响范围和权威度.规则包括个体交互规则和个体与媒体的交互规则.通过仿真证明了模型是合理的,并且用该模型来仿真媒体对舆论演化的引导作用,从媒体的数量和报道频率2个方面研究媒体在舆论形成过程中的引导作用,结果发现积极媒体的数量越多对舆论的引导作用越强,媒体的报道频率增加会对舆论的形成产生积极效果,但是超过一定次数时对舆论的影响作用有限.最后通过对模拟结果的分析,提出了通过媒体来引导舆论的方式.
A dynamic model of opinion maki agents, media, and the rules for interaction ng in a multi-agent media system was developed. The model contained between them. Agent attributes included values for the degree of trust between them, for credibility, and for conformity. Media attributes were influence and authority. The rules of interaction included agent rules as that allowed agent interactions with media. Simulation results proved that the model was reasonable. Increased frequency of reports had a positive effect on the formation of public opinion. Nevertheless, when a critical number of reports was exceeded, further influence became limited. Based on analysis of the outcome, the best way to guide the formation of opinions was proposed.
