评价关系转化及其在群组评价中的应用

评价关系是评价群体形成关于被评价对象群体性认知的重要因素之一,根据参与者的主观经验、学习和认知特征、评价群体的网络结构特征和参与者主观偏好的相似性,定义了由关系度、局部链接中心性测度和参与者偏好相似性测度构成的评价关系,讨论了评价关系转化形式、评价关系优先序算子及其权重向量的确定,给出评价关系优先序算子性质。考虑评价关系的群组评价方法能够差异化处理由于评价目标、评价规则和评价群体特征带来的具体问题,形成有针对性的,由关系值和评价值构成的二元群组评价结论。

Evaluation Relation Transformation and its Application in Group Evaluation

Evaluation relation is one of the important factors in evaluating a group.According to participants’ subjective experience,learning and cognitive characteristics,and a group’s network structure characteristics and similarity of the participants’ preference,this paper defines evaluation relation as comprising of the degree of relations,measurement of local link centrality,and the similarity of participants’ preference.It discusses evaluation relation transformation,priority aggregation operator of evaluation relations and its weight vector calculation,and analyzes the nature of evaluation relation priority aggregation operator.Considering group evaluation method in evaluation relations could treat differently the specific issues caused by evaluation objectives,evaluation rules and group identity,to form a targeted binary groups evaluating conclusion composed by relation and evaluation value.
