In the paper, the authors discuss a new approach to extract rare association rules that can be defined as the rules containing the rare items or infrequent items in the dataset. For extracting rare item sets, various efforts have been done. One of them is MS Apriori method which finds the rare association rule. This paper works up to some extent, which suffers from "Rare item problem" dilemma. To extract rare item sets effectively, an approach has been proposed that would allow user to specify multiple minimum support that reflects the nature of items and their varied frequencies in database.
