Mobile social networks are dominating in our society’s daily life because of fast advancements of information technologies. To further exploit benefits from the ubiquitous service, studying the influence of information dissemination in this kind of social network becomes a necessity. This paper proposes a mobile social network influence model with regard to multiple roles. In the model, the concept of group is adopted to analyze a user’s role in different contexts. Through the introduction of role’s level and group’s relativity, information dissemination can be investigated deeply, and then, with the Floyd-Warshall algorithm, information strength matrix is constructed to study each node’s influence and under-influence indexes in the network, in addition, the comprehensive influence under multi-role view is also expressed distinctly in the fuzzy form. The result of this research will help find out preferable information disseminators as a new business strategy in e-commerce. Furthermore, it is also useful for detecting gossips and controlling its dissemination in social management.

多角色视角下的移动社交网络信息传播影响模型

由于信息技术的快速发展，移动社交网络在我们社会的日常生活中占主导地位。为了进一步利用无处不在的服务带来的好处，研究信息传播在这种社交网络中的影响成为必要。本文提出了一种多角色的移动社交网络影响力模型。在模型中，采用组的概念来分析用户在不同上下文中的角色。通过引入角色等级和群体的相关性，可以深入研究信息传播，然后利用Floyd-Warshall算法构建信息强度矩阵，研究网络中各个节点的影响力和影响力不足指标，此外，多角色视角下的综合影响也以模糊的形式表现得比较明显。这项研究的结果将有助于找出可取的信息传播者作为电子商务中的一种新的商业战略。此外，它还有助于检测八卦并控制其在社会管理中的传播。
