A Novel Quantity based Weighted Association Rule Mining

Classical association rule mining algorithm discovers frequent itemsets from transactional databases by considering the appearance of the itemset and not other utilities such as profit of an item or quantity in which items bought. But in transactional databases large quantity of items is purchased may lead to very high profit even though items appeared in few transactions. Therefore the quantity of the item is considered as the most important components, lack of which may lead to loss of information. Here binary attributes of the Item is considered for calculating item weight using link based model. This paper provides novel framework, Quantity Based Association Rule Mining (QBARM) algorithm, considers quantity and item weight.
