中文摘要: 在线Web交互网络信息传播的实时性、规模性和难以控制性使突发性群体事件更加难以分析、感知和预测,带来了潜在的社会公共安全风险。现有研究成果尚不能很好地刻画交互网络结构特征,基本理论难以对信息管理提供有效支持,因此,信息敏捷感知和传播预测等基本理论和技术亟待完善与突破。本项目针对交互网络信息传播动态行为,以复杂网络理论为基础,进行以下四个方面的研究:分析网络结构和社会属性,构建基于社区的交互网络状态模型,揭示节点、社区和全局拓扑演化机制;面向动态演化特性,基于局部知识设计高效算法,完成局部重叠社区发现;基于动态社区结构,建立影响力评价模型,设计影响力节点发现算法,构建信息敏捷感知机制;分析节点多维属性和话题偏好特征,建立节点转发模型,形成信息传播范围预测机制;最终设计交互网络动态信息监视与影响分析原型系统,对理论成果进行验证和完善,为在线交互网络的信息管理、舆情分析提供理论和技术支撑。

英文摘要: The real-time, large-scale and difficult control attributes of information dissemination on Web Interactive Network make it very hard to analyze,perceive and predict the abrupt mass events, and bring potential risk of huge social public safety. Existing research still can not describe the structural characteristics of the interactive network very well, the basic theory is difficult to effectively support the network information management,so the basic theory and technology about information agile perception and dissemination prediction urgently need to be improved and broken through.To explore the information dissemination dynamic behaviors, based on the complex network theory, this project carries out the following four aspects research: Firstly, we analyze the network structure and social attributes to build interactive network state model from the point of community, revealing the nodes, community and global topology evolution mechanism. Secondly, considering dynamic evolution features, the efficient algorithms are designed using local knowledge to find the local and the overlapping communities. Thirdly, the influence evaluation model of nodes is conceived based on the dynamic community structure to design algorithm for obtaining the influencing node set, and build up the prompt information perception mecha
