摘　　要：在Web网络中承载着不同的协议和网络信道,由此产生危险信息,给网络信息空间带来安全威胁,通过对危险Web信息的准确挖掘,可净化网络空间,确保网络安全。传统方法采用模糊关联规则算法进行危险Web信息分类挖掘,在干扰背景下,模糊聚类过容易受到干扰,导致很难建立有效的关联规则,挖掘效率较低。提出一种基于改进关联规则的危险Web信息挖掘技术。在建立关联规则前,引入Takens定理进行危险Web信息数据的相空间重构,构建Web网络的危险信息挖掘的信道模型,并对危险Web信息的信息流多源进程进行分类设计。设计自适应IIR级联滤波算法进行数据干扰滤波,运用以上方法对规则关联过程进行改进,实现危险Web信息的准确挖掘。仿真实验进行了性能验证,结果表明,采用该算法进行危险Web数据挖掘,去干扰性能较好,精度较高。The security of cyber information space is threatened by the hazard information that caused by different protocols and network channels in Web network,and the cyber space is purified to ensure the network security by mining the hazard Web information accurately. The algorithm of the fuzzy association rules are used in the traditional method to excavate and classified the dangerous Web information. The fuzzy clustering is easy to be disturbed in the influence background and has low efficiency,so it is hard to establish effective association rules. Because of this,the risk Web information mining technology based on the improved association rules is proposed. Before establishing the association rules,Takens theorem is introduced to reconstruct the phase space of the hazard Web information data to establish the channel model for the hazard information mining in Web network and make classification design for the multisource progress of the risk Web information flow. An adaptive IIR cascade filtering algorithm is designed to filter the data influence,improve the progress of the association rules,and realize the accurate mining of the risk Web information. The simulation results for the performance verification show that this algorithm has advantages of good filtering interference performance and high accuracy.
