【摘要】： 随着信息时代的进步以及互联网和通信技术的发展,手机信息业务作为一种新兴的传播手段,以其价格低廉、收发方便、不受时空约束等优点,已成为一项比较重要的交流手段并深受手机用户的欢迎。对手机信息传播的了解都只是微观层面上的,手机信息的使用者不能宏观量上理解信息的传播情况。为了建立手机信息传播的模型,采用的是复杂系统的建模工具——元胞自动机。元胞自动机是由大量简单的、具有局部相互作用的元胞构成的一个空间离散、时间离散、状态离散的模型。手机信息的传播不受时间空间的约束,正好符合元胞自动机的这几个特点。因此,本文主要从定性和定量的方面来建立手机信息传播的元胞自动机模型。首先简要介绍了元胞自动机有关理论内容,为最后建立手机信息的元胞自动机模型提供理论基础。接着是数据的收集与分析。先是根据手机信息的内容将手机信息分为十类:祝福类、问候类、娱乐类、新闻类、笑话类、聊天类、广告类、通知类、倡议类(如抵制家乐福字样的短信)、提醒类(如四川广元柑橘事件)等。目的主要是分别研究各类手机信息传播的模型,模拟其传播的过程和范围。然后根据研究对象的特点将元胞自动机中的八个邻元设定为:父母、兄弟姐妹、亲戚、朋友、同学、同事、老师和其他八类。接着设计调查问卷,利用在线调查的方式来获得手机信息使用情况的数据,最重要的是获得了元胞向周围的八个邻元转发手机信息的概率。最后就是利用此概率来建立元胞自动机模型,模拟各类手机信息传播的过程。此外还分析了模型的特点和产生这种结果的原因。
[Abstract]:With the progress of the information age and the development of the Internet and communication technology, the mobile phone information service, as a new means of communication, is cheap, convenient to receive and receive, and not subject to space-time constraints. Has become a more important means of communication and popular with mobile phone users. The understanding of mobile phone information dissemination is only micro level, mobile phone information users can not understand the dissemination of information macroscopically. In order to establish the model of mobile phone information transmission, the cellular automata, the modeling tool of complex system, is adopted. Cellular automata (CA) is a spatial discrete, time-discrete and state-discrete model composed of a large number of simple, locally interacting cells. The transmission of mobile phone information is not restricted by time and space, which accords with the characteristics of cellular automata. Therefore, the cellular automata model of mobile phone information transmission is established from qualitative and quantitative aspects. Firstly, this paper briefly introduces the theory of cellular automata, which provides a theoretical basis for the establishment of cellular automata model of mobile phone information. Then there is the collection and analysis of data. First of all, according to the content of mobile phone information, the mobile phone information is divided into ten categories: blessing, greeting, entertainment, news, jokes, chat, advertising, notification, advocacy (such as text messages boycotting Carrefour). Reminders (such as the Guangyuan citrus event in Sichuan). The purpose of this paper is to study the models of mobile phone information transmission, and to simulate the process and scope of its spread. Then according to the characteristics of the subjects, the eight neighbor elements of the cellular automata are set as: parents, brothers and sisters, relatives, friends, classmates, colleagues, teachers and other eight categories. Then the questionnaire is designed to obtain the data of mobile phone information using online survey. The most important thing is to obtain the probability that the cell can transmit the mobile phone information to the eight neighboring elements around. Finally, using this probability to establish cellular automata model, simulate the process of various mobile phone information transmission. In addition, the characteristics of the model and the reasons for the result are analyzed.
