摘　　要：为了有效地挖掘用户所需的序列模式,在序列数据库中对每个项目引入了兴趣度值以示其不同的重要程度。在对概念格模型进行扩展的基础上,提出了基于兴趣度的序列概念格模型及其构建算法。实例表明算法能减少冗余序列的产生,挖掘出满足用户需求的序列模式。In order to mine efficiently the sequential patterns according to user＇s requirements, the interest measure for every item was introduced to reveal the different importance in the sequence database. And on the basis of extending the concept lattice model, the sequence concept lattice model with interest measure and its construction algorithm were presented. The instance shows that the algorithm can reduce the redundant sequences and mine the sequential patterns that satisfy user＇s requirements.
