摘　　要：针对社会网络环境下的大群体分类决策问题,首先,通过构建个性化相似度阈值学习模型,将相似度与社会网络融合,得到修正后的社会网络;然后,利用子网络分割算法将社会网络划分为具有一定特征的子网络,并形成对应的子群,通过DeGroot模型计算子群的群体偏好;接着,在群体偏好聚合过程中,综合偏好顺序一致性程度、子群内聚力及其成员数量,并通过参数学习计算三个指标的最优权重分配,进而计算子群权重.最后,通过一个算例来验证方法的有效性和可行性.In order to solve the problem of large group classification decision-making in social network environment,firstly,we construct a personalized similarity threshold learning model,integrate the similarity with social network,and get the modified social network;then,we use sub-network segmentation algorithm to group decision-makers,and compute the group preferences of subgroups through DeGroot model;next,we integrate the degree of consistency of the preference order,cohesion of subgroups and the number of their members in the process of aggregation of group preferences,and compute the optimal weight assignment of three indicators through parameter learning,and then compute the weights of subgroups.Secondly,in the process of group preference aggregation,we combine the degree of preference order consistency,subgroup cohesion and its number of members,and calculate the optimal weight assignment of the three indexes through parameter learning to compute the subgroup weights.Finally,the validity and feasibility of the method are verified by an example.
