Abstract

Incremental association mining refers to the maintenance and utilization of the knowledge discovered in the previous mining operation for later association mining. In paper, we propose a notion called maximal itemset based on which large itemsets with dynamic minimum support can be identified easily. When new transactions are inserted into a database, the maximal itemsets of the new database can be generated from previous maximal itemsets and new transactions.
