Super set of iemset x ) according to constrained subtree of itemset x, if item “ a ” isn ’ t a fuzzy item, we don ’ t scan database in addition. it can be generated by ffp tree. we propose two order methods for constructing ffp tree. one is that sorting database attributes holding frequent item in ascending order of their nodes number in ffp tree. another is that sorting frequent item of not fuzzy attributes in descending order of their support firstly, then sorting database fuzzy attributes with frequent item in ascending order of their nodes number in ffp tree. our experimental results show that although fmf needs more space costly than the algorithms based on apriori, its time costly is obviously lower than the latter
針對ffp -樹的生成，提出了兩種排序方法:按屬性順序將每個屬性下的頻繁項目依次插入到頭表中，屬性按照其在ffp -樹中可能的不同結點的個數從少到多進行排序;先對非模糊屬性下的頻繁項目按支持度從大到小進行排序，再對模糊屬性按其在ffp -樹中包含的不同結點的個數，從少到多進行排序，然後依次將各屬性下的頻繁項目插入到頭表中。 -
