1. Introduction
Data mining can help derive useful knowledge from databases. Among its technology, association-rule mining [1,3,28] considers frequency relationship among items and is commonly applied to many applications. A transaction usually includes the items bought and the time of its occurrence. Besides, the periods for items to be exhibited are also important. Some researches about temporal data mining were thus presented [27]. For example, the time period for an item may be the entire time interval of a database [5], the duration from the first occurring time of the item to the end of a database [20], or the on-shelf time periods of the item [8]. However, an infrequent item for the entire time interval may be frequent within part of the time.In this paper, we thus organize time into granules and consider temporal data mining for different levels of granules. We use the first transaction including an item as the start point for the item. We propose a three-phase mining framework with consideration of the above item lifespan definition to mine temporal association rules with time granules from a temporal database. According to the definition of item lifespan, in the first phase, each elementary time interval is processed. The temporal frequent itemsets within the above intervals are first found, and then the itemsets are identified as candidate temporal frequent ones in all the time granules of the upper level of the hierarchy. These candidates are then judged for being temporal or not at each level of granules. Additional database scans may be needed to find the actual supports of the candidates. In the third phase, the possible candidate association rules are derived from the temporal frequent itemsets at each level. Their confidence values are then calculated and compared with the minimum confidence value to get the final temporal association rules.
