Developer’s Description

By Christian Borgelt
Find frequent item sets using extension of the Eclat algorithm.
JIM is a program to find Jaccard item sets with an extension of the Eclat algorithm. In analogy to frequent item set mining, where one tries to find item sets the support of which exceeds a user-specified threshold (minimum support) in a database of transactions, a Jaccard item set is an item set for which the (generalized) Jaccard index of its item covers exceeds a user-specified threshold. This measure yields a much better assessment of the association strength of the items than simple support. Since the (generalized) Jaccard index is like the support also anti-monotone, the same basic approach can be used for the search provided. It is extended to compute the denominator of the Jaccard index.
