【摘要】 提出了一种间断序列分析方法,实现了应用序列模式分析提取网络环境下用户正常行为模式。并在此基础上提出了基于栈结构的支持度计算算法,该算法仅对数据库进行一次扫描,即可实现候选序列的计数操作。实验证明该算法具有较好的实用性。更多还原

【Abstract】 The paper presents a break sequences analysis method for such situation and implements extracting the users normal behavior patterns by using sequential analysis in the network environment.Then it presents a support computing algorithm based on stack structure,which can count the candidate sequences by scanning the database only once.The tests show that the algorithm is practical.更多还原
