摘要: In the past, we proposed incremental mining algorithms for maintenance of sequential patterns based on the concept of pre-large sequences as records were inserted or deleted Although maintenance of sequential patterns for record modification can be performed by usage of the deletion procedure and then the insertion procedure, twice computation time of a single procedure is needed In this paper, we thus attempt to apply the concept of pre-large sequences to maintain sequential patterns as records are modified. The proposed algorithm does not require rescanning original databases until the accumulative amount of modified customer sequences exceeds a safety bound derived by pre-large concept. As databases grow larger, the numbers of modified customer sequences allowed before database rescanning is required also grow.
