面向评价局部环境的群评价长效机制分析

在群组评价问题中,称评价参与者(即节点集)及参与者之间的评价关系构成群组评价局部环境,即评价群体的网络结构。将评价局部环境看作是一个有限状态、不可约且非周期性马尔可夫过程,使得群组评价问题水平维度的评价局部环境基于时间维度进行拓展,证明参与者对评价关系的调整可以改善群体网络结构的稳定性;具有评价关系的参与者状态正相关;参与者不满意效用状态持续时间的增加降低了其达到满意效用状态的概率。在此基础上,讨论以被评价对象为主要研究对象设置群组评价方法,根据三种常见的评价局部环境状态,考察评价群体的群体性行为或认知趋势性特征,在此基础上讨论评价目标的可执行性。允许有关被评价对象的新信息注入群组评价系统,在长期分析评价群体的群体性评价行为的趋势特征,据此构建面向评价局部环境的群组评价方法,分析评价目标的可执行性,以期使群组评价行为具有稳定性和可预见性。

Group Evaluation Long-term Mechanismanalysis under Giving Evaluation Environment

This paper studies long-term mechanism of group evaluation problem. The group evaluation process is taken as a Markov process with Limited Status, Irreducible and aperiodic. And we define the partial evaluation environment is the group structure consisting of participants and theirs’ evaluation relationships. And we prove the following: (1) group structure could more stable through participants adjusting their evaluation relationships; (2) participants are positive correlation if there are evaluation relationships between them; (3) participants with different state will cluster if their original states last. We analysis evaluation objectives enforceability under three common evaluation environment, and the trend features of group cognition or behaviors. On this basis, long-term mechanism of group evaluation allow new information to be injected, and restore evaluation objectives as constraints.
