So, this paper, based on mathematical expectation, brought up the concept of the positively correlated frequent itemsets, and improved the algorithm of mining frequent itemsets directly in FP-tree to mine positively correlated frequent itemsets. In this way, a solution to the above mentioned problems was got.
