摘要
针对大群体应急决策中环境复杂多变及公众参与度较低的问题,提出一种数据分析驱动的大群体应急决策公众专家动态协同方法。首先,通过对社交媒体平台中的文本数据进行情感分析,分别从属性层和综合层评价大群体应急决策质量;其次,根据属性层决策质量提出了属性权重动态更新规则;然后,在社会网络环境下基于综合决策质量及专家偏好与群体偏好的距离动态更新专家间的信任关系,并使用改进PageRank算法计算专家权重;最后,通过某飞行器事故的案例应用和对比分析验证了所提方法的有效性和优越性。
Aiming at the complex and changeable environment and the low public participation in large-group emergency decision-making,a data-driven dynamic collaborative method of public and experts in large-group emergency decision-making is proposed.Firstly,the sentiment analysis is carried out on text data in social media platforms to evaluate the quality of large-group emergency decision-making from attribute level and comprehensive level respectively.Secondly,according to the decision-making quality of attribute level,the dynamic update rules of attribute weight are proposed.Then,under the social network environment,the trust relationship between different experts is dynamically updated based on the comprehensive quality of decision-making and the distance between experts’preference and groups preference,and the expert weight is calculated by the PageRank algorithm.Finally,the effectiveness and superiority of the proposed method are verified through the case application and comparative analysis of an aircraft accident.
