Mining sequential patterns is an important problem in the field of data mining and many algorithms and optimization techniques have been published to deal with that problem. An GSP algorithm, which is one of them, can be used for mining sequential patterns with some additional constraints, like gaps between items. Taxonomies can exist upon the items in sequences. It can be applied to mine sequential patterns with items on several hierarchical levels of the taxonomy. If a more general item appears in a pattern, the pattern has higher or at least the same support as the one containing the corresponding specific item. This allows us to mine more patterns with the same minimal support parameter and to reveal new potentially useful patterns. This paper presents a method for mining multi-level sequential patterns. The method is based on the GSP algorithm and generalization of more specific sequences based on the information theory.
