To reduce the generation of candidate sequences and the scans to sequence database for
AprioriAll algorithm, an efficient sequential pattern mining method based on improved AprioriAll
algorithm is presented. Firstly, data are preprocessed. Then do the sequential pattern mining with
improved AprioriAll algorithm. The improvements of AprioriAll algorithm are mainly two points:
one is to change the connection of candidate sequences to reduce the generation of candidate
sequences; the other is to reduce the needless database scans to improve the efficiency of
algorithm. Finally, the efficiency and validity of improved AprioriAll algorithm is validated
through experiments.
