| Abstract: | In this paper, the scope of discovery of sequential pattern has been extended from single level to multiple level, that is, discover sequential pattern among the objects in the same concept level or in different level. And a top-down and progressively deepening method for discovering sequential pattern in each different level has been put forward. |

| Keywords: | Knowledge discovery generalized sequential pattern concept hierarchy |
