%X Time has not been taken into account in the current international researches of association rules. However, time is an inherent property in the real world. Ther e exists temporal semantics in many real world databases. The temporal constrain t problem called valid time is considered in this paper. Both the methods for ex tending and merging time intervals and the new discovery algorithm for temporal association rules are proposed. Thus, the application of association rules h as been further generalized.
