中文摘要：

在分析网络舆情突发事件的成因和应急决策特性的基础上,从舆情状态、突发事件警情和民众关注三个方面构建网络舆情突发事件应急决策的指标体系。由于舆情事件的不确定性、复杂性,单一方法难以做出有效的决策,本文提出一种综合模糊语言变量、加权欧式距离以及优先集成算子的针对舆情事件应急决策的模糊多属性群决策模型。以模糊语言变量给出舆情事件在属性下的评价,然后使用基于加权欧式距离的方法计算专家的决策评价与平均的群体评价之间的距离,以反向调整专家的初始权重,增强群体意见一致性。现实应急决策问题中,决策指标通常有不同的优先级,本文使用优先集成算子集成舆情事件决策信息,得到最终决策评价值,进而对各舆情事件按紧急度排序。最后,通过一个实例验证本文方法的有效性。

英文摘要：

On the basis of analyzing causes of Internet public opinion emergency（IPOE）and features of the emergency decision,the index system of the emergency decision for IPOE is constructed from three aspects：The states of Internet public opinion,emergency alarm and public attention.Due to the uncertainty and the complexity of IPOE,a single method is difficult to make effective decisions.A fuzzy multi-attribute group decision-making model that combines fuzzy linguistic variables,weighted Euclidean distance and prioritized aggregation operators is proposed against Internet public opinion emergency.Taking fuzzy linguistic variables as the evaluation set of the IPOE,a weighted Euclidean distance-based method is put forward to calculate the distance between the decision evaluation of an expert and the average decision evaluation.In so doing,the original weights of experts can be adjusted reversely to enhance the group consensus.In real decision problems,this indexes have different priorities commonly.A linguistic prioritized weighted average operator is developed for integrating the evaluation values of IPOE,and then all IPOEs will be ranked by their final evaluation values.Finally,apractical example is given to verify the practicality and effectiveness of the proposed approach.
