    Thanks any advices in advance.

    sorry, the last messenge is not clear.My problem is as follows:

    Given two itemsets
    T={i1,i2,¡­,im}, T¡¯={j1,j2,¡­,jn}, m¡Ùn
    also know the distance between any pair of elements from T and T'

    how to define the similarity between T and T', in other words,
    given a target itemset, I need to query the similarity itemset from
    many many other itemsets.
