摘要
在突发事件的信息传播系统中，分别针对手机、人、互联网信息载体三种最为活跃和最具代表性的要素建立三种类型的信息传播网络，并根据三者间的关联关系将它们集成起来，构建一个“超网络”模型，并通过例子构建超网络的邻接矩阵和网络直观图；在超网络视域下，针对现有算法的不足，提出一种新的重要节点的判定算法，并通过例子进行验证与分析。
The mobile phone, person and Internet information carrier are the most active and representative elements in the emergencies information dissemination system. This paper, based on the theory of supernetwork, presents a supernetwork model which comprises mobile phone network, the personnel network and the Internet information carrier network, and the complex interrelations among them. It builds the adjacency matrix and the visual network graph of the supernetwork through an example. Based on the lack of existing algorithm, this paper proposes a new algorithm to determine the important nodes from the perspective of supernetwork. Finally, the new algorithm is illustrated through an example.
