从猎鹿博弈论风险性话语

A Discussion of Risky Speech Based on Stag Hunt Game Theory

猎鹿博弈论述的是弈者合作共赢的利益问题。运用博弈建模阐释语言交际中的风险性话语,即可能导致交际失败、需双方共同合作的话语;同时利用Parikh的博弈模型通过形式化的途径来理解交际过程。交际者会对话语传递的准确性、适当性等进行调整以期效用最大化。语言交际亦如经济活动,风险偏好者和风险厌恶者为不同的效用转换着各自的策略和角色。

Stag Hunt Game is about players who realize mutual gains by making cooperation. Real discourse is modeled with stag hunt game to explain the risky speech,which needs more mutual cooperation and may result in failure communication. Parikh＇s model provides an explicit formalism for understanding the communication process. Communicators will adjust the accuracy and appropriateness of their words for maximum utility. Language communication is like economic activities,in which risk- averse players and？ risk- seeking players switch their strategies and roles for different utilities.
