AbstractAssociation rules are important one of data mining activities. All algorithms of association rule mining consist of finding frequency of itemsets, which satisfy a minimum support threshold, and then compute confidence percentage for each k-itemsets to construct strong association rules’. Some of these association rules are not important
because the extracted knowledge from their is found in other. Hence we proposed algorithm to construct only important association rules by depend on closed frequent itemset. An itemset is closed if one of its immediate supersets has the same support as the itemset. Finding these closed frequent itemsets can be of a great help to purge a lot of
itemsets that are not needed to find association rules. So that aid to reduce execution time and work space of algorithm and end the algorithm at any level of k-itemset, without construct all K-itemset.
