The paper presents an agent based simulation of opinion evolution, based on a nonlinear emotion/information/opinion (E/I/O) individual dynamics, to an actual Internet discussion forum. The goal is to reproduce the results of two-year long observations and analyses of the user communication behavior and of the expressed opinions and emotions, via simulations using an agent based model. The model allowed to derive various characteristics of the forum, including the distribution of user activity and popularity (outdegree and indegree), the distribution of length of dialogs between the participants, their political sympathies and the emotional content and purpose of the comments. The parameters used in the model have intuitive meanings, and can be translated into psychological observables.
本文基于非线性情感/信息/观点（E/I/O）个体动态，对一个实际的互联网讨论论坛进行了基于主体的观点演变模拟。目标是通过使用基于主体的模型进行模拟，重现对用户交流行为以及所表达的观点和情感进行的为期两年的观察与分析结果。该模型能够得出论坛的各种特征，包括用户活跃度和受欢迎程度的分布（出度和入度）、参与者之间对话长度的分布、他们的政治倾向以及评论的情感内容和目的。模型中使用的参数具有直观意义，并且可以转化为心理学可观测指标。
