In this age of Facebook, Instagram, and Twitter, there is rapidly growing interest in understanding network-enabled opinion dynamics in large groups of autonomous agents. The phenomena of opinion polarization, the spread of propaganda and fake news, and the manipulation of sentiment is of interest to large numbers of organizations and people. Whether it is the more nefarious players such as foreign governments that are attempting to sway elections or it is more open and above board, such as researchers who want to make large groups of people aware of helpful innovations, what is at stake is often significant.In this paper, we review opinion dynamics including the extensions of many classical models as well as some new models that deepen understanding. For example, we look at models that track the evolution of an individual’s power, that include noise, and that feature sequentially dependent topics, to name a few.While the first papers studying opinion dynamics appeared over 60 years ago, there is still a great deal of room for innovation and exploration. We believe that the political climate and the extraordinary (even unprecedented) events in the sphere of politics in the last few years will inspire new interest and new ideas.It is our aim to help those interested researchers understand what has already been explored in a significant portion of the field of opinion dynamics. We believe that in doing this, it will become clear that there is still much to be done.

从古典到现代的意见动态

在这个 Facebook、Instagram 和 Twitter 的时代，人们对​​了解大型自治代理群体中基于网络的意见动态的兴趣迅速增长。舆论两极分化、宣传和假新闻的传播、情绪操纵等现象引起了广大组织和民众的关注。无论是更邪恶的参与者，例如试图影响选举的外国政府，还是更开放和光明正大的参与者，例如希望让大批人意识到有用的创新的研究人员，所面临的风险往往是重大的。在本文中，我们回顾了意见动态，包括许多经典模型的扩展以及一些加深理解的新模型。例如，我们查看跟踪个人权力演变的模型，包括噪声，以及具有顺序相关主题的特征，仅举几例。虽然第一篇研究意见动态的论文出现在 60 多年前，但仍有很大的创新和探索空间。我们相信，过去几年的政治气候和政治领域的非凡（甚至是前所未有的）事件将激发新的兴趣和新的想法。我们的目标是帮助那些感兴趣的研究人员了解已经在重大领域探索的内容意见动态领域的一部分。我们相信，在这样做的过程中，很明显还有很多工作要做。我们相信，过去几年的政治气候和政治领域的非凡（甚至是前所未有的）事件将激发新的兴趣和新的想法。我们的目标是帮助那些感兴趣的研究人员了解已经在重大领域探索的内容意见动态领域的一部分。我们相信，在这样做的过程中，很明显还有很多工作要做。我们相信，过去几年的政治气候和政治领域的非凡（甚至是前所未有的）事件将激发新的兴趣和新的想法。我们的目标是帮助那些感兴趣的研究人员了解已经在重大领域探索的内容意见动态领域的一部分。我们相信，在这样做的过程中，很明显还有很多工作要做。
