| 摘 要： | 针对模糊关联规则挖掘时隶属函数的确定困难以及区间划分边界过硬等问题,提出了模糊关系关联规则挖掘算法,确定了关系等级数目和相邻等级相似度,将语言表达式(事务的属性值)根据模糊运算规则映射到标签集的各个等级上得到等级权值。在这些权值的基础上定义了模糊关系支持度和置信度,阐述了算法的详细步骤,最后给出了算法在服务信任领域挖掘关联规则的应用过程。

| Abstract: | For the difficult determining of the membership function and the hard border of interval division when the fuzzy association rules are mining,association rules mining algorithm based on fuzzy relation is proposed.After the relation grade numbers and the similarity of neighbor grades are determined,the linguistic expressions(the properties of transactions) are mapped to each grade of the label set and then get the grade ratings as the weights.Based on these weights,the fuzzy relation support and confidence are defined.The detailed steps of the algorithm are elaborated in this paper.At the end of this article the application of this proposed algorithm about mining association rules in service trust area is described. |
