双语和谐微观仿真模型与计算实验

Bilingual Harmony Micro-simulation Model and Computational Experiment

城镇化背景下,社会网络弱连接关系增多,对弱势语言保护提出了挑战。基于改进的agent社会圈子网络建模方法构建了具有远程弱连接关系的新型社会网络;不同人群语言演化机制上除考虑语言地位和语言人口比例的影响外,引入了双语者对单语者向双语者转变的影响力、语言态度和网络连接关系对语言选择行为的影响新机制;给出了改进的agent语言水平和垂直传播模型。计算实验结果表明:在社会网络弱连接关系增多背景下,培养积极的语言态度、提高双语者对单语者向双语者转变的影响力等措施有利于形成稳定的全民双语型社区。

Under the background of urbanization,the weak connection of social networks has increased,which has challenged the protection of vulnerable languages.A new social network with remote weak connection is constructed based on the improved modeling method of agent social circle network;in addition to considering the influence of language status and the language population ratio on the language evolution mechanism of different populations,a new mechanism is introduced for the influence of bilinguals on the transition from monolingual to bilingual,and the influence of language attitudes and network connections on language choice behaviors;an improved agent language level and vertical propagation model is presented.The results of calculation experiments show that in the context of increasing weak connections on social networks,fostering positive language attitudes and improving the influence of bilinguals on the transition from monolinguals to bilinguals are conducive to forming a stable bilingual community.
