| 本文将序贯模式的发现从单层（SingleLevel）概念扩展到多层（MultipleLevel）概念．即既允许在同层概念之间，也允许在不同层概念之间发现序贯模式，提出了发现广义序贯模式的自顶向下逐层递进的方法． |

| 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. |
| Key words: Knowledge discovery generalized sequential pattern concept hierarchy |
