针对传统挖掘算法生成的关联规则存在大量冗余、难于理解和应用的问题,提出一种新的频繁闭项集概念格FCIL(Fre-quent Closed Itemsets Lattices),用于生成无冗余关联规则。首先,对概念格理论进行研究,概念格节点间的泛化和例化关系非常适合规则提取;然后,结合频繁闭项集能有效减少规则数目的特点,构建一种新的FCIL;最后,给出FCIL构造算法和相应的规则提取算法。实验表明,该方法能够高效地产生无冗余规则集。

Association rules generated by traditional mining algorithm have a large number of redundancies,which are hard to be understood and applied.Aiming at this problem,we present a new frequent closed itemset concept lattice (FCIL),which can generate non-redundancy association rules.First,we study the theory of concept lattice,the generalisation and specialisation relations between the nodes of concept lattice are very suitable for rule extraction;then,we build a new FCIL in combination with the characteristic of frequent closed itemsets which can effectively reduce the number of rules;finally,we develop the FCIL construction algorithm and the corresponding rules extraction algorithm.Experiment shows that the proposed method can efficiently generate non-redundancy rules set.
