基于Agent的情感劝说的决策过程及模型研究

Agent具有情感后进行的劝说决策会更加理性,而现有研究还不够全面深入。针对此问题,首先结合形式逻辑理论,定义了基于Agent的情感劝说及其决策过程,并将基于Agent的情感劝说的决策过程划分为评价情感劝说行为、更新情感劝说状态、调整情感劝说目标、产生情感劝说行为四个阶段;其次针对这四个阶段,结合OCC情感模型和PAD心情模型,运用多属性效用理论,引入情感淡化因子和情感评价因子,定义了Agent情感触发函数,建立了八种Agent基本情感与劝说目标的映射关系,将Agent的情感劝说行为分为奖励型、申辩型、威胁型和反辩型四类,分别构建了相应的决策模型,从而构成了更加完整和合理的基于Agent的情感劝说的决策过程模型;最后通过算例证明了模型的合理性和有效性。

Agent-based on emotional persuasion decision process and model

With the rise of the Internet environment,automatic negotiation has become a research hotspot in the field of artificial intelligence.Especially in the complex negotiation environment,Agent has made the negotiation process more efficient because of its unique intelligence and interaction,and persuasive negotiation takes full consideration of persuasion factors and makes full use of persuasion,making the negotiation process more rational.Because emotion affects human cognition,goal and behavior,it plays an important role in human decision-making process.Therefore,emotion is an integral part of the field of artificial intelligence.Emotion is introduced into the field of Agent persuasion.By constructing emotional Agent,the intelligence and adaptability of Agent are improved and agent persuasion behavior is made.It is more consistent with human behavior,which has become the consensus of scholars.In the related research,the scholars and experts in this field have studied the persuasion based on Agent and the construction of emotional Agent from different angles,but there are the following problems:1.the research on emotion is not comprehensive,especially the study of emotion calculation;2.the research on the application of emotional theory to the Agent persuasion field is less;3.to Agent More research is on the protocol mechanism,less research on the process of persuasion,especially the influence of emotion on the Agent persuasion process.In order to solve these problems effectively,this paper takes emotion as an important factor in the process of Agent persuasion,and focuses on Agent's emotional persuasion decision-making process.First,the formal model based on the Agent emotional persuasion decision process is defined.Then the emotional persuasion decision-making process is defined and divided.The emotional persuasion decision process based on Agent is divided into four stages:the evaluation of emotional persuasion,the renewal of emotional persuasion,the adjustment of the emotional persuasion target,and the emotional persuasion.Secondly,through the influence of Agent's personality on emotional trigger threshold,the emotion desalination factor is introduced,Agent emotional trigger function is defined,and the renewal emotion is built in the persuasion state model.Again,the mapping relationship between eight basic emotions and targets is established by defining emotional evaluation factors,and the emotional persuasion target model is constructed.In the end,the emotional persuasion behavior is divided into four categories:incentive emotional persuasion,pleading emotional persuasion,threatening emotional persuasion and antiplea emotional persuasion,and setting up the principle of emotional persuasion and target matching,and constructing emotional persuasion behavior model.Finally,a complete emotional persuasion decision-making process is formed,and the rationality and validity of the model is proved by an example.To illustrate the above decision process and the effectiveness of the model,an example is designed and analyzed.The example shows that emotional persuasion plays an important role in the decision-making process of Agent and the generation of emotional persuasion.If Agent evaluates the current persuasion to produce happy,dependent,relaxed,gentle,and so on,the emotion that has positive pleasure will encourage Agent to generate incentive or plea emotional persuasion.On the contrary,the feelings of negative pleasure,such as hostility,disdain,boredom,and anxiety,may cause Agent to defer or plead.Type of emotional persuasion.Based on this,the validity of the model is verified,and the important influence of emotion on persuasion decision process is also illustrated.
