摘要
A pattern mining method includes obtaining, according to each of transactions comprised in a transactional database, a candidate pattern set satisfying a condition, each of the transactions comprising at least one item, each of candidate patterns in the candidate pattern set comprising one or more items in an itemset, calculating a utility of a respective one of the candidate patterns in each of the transactions, determining, among the transactions, at least one target transaction in which the utility reaches a specified utility threshold, determining a target period value of a target candidate pattern corresponding to the at least one target transaction, according to a target time attribute of each of the at least one target transaction, and determining the target candidate pattern as a mining result, based on the target period value of the target candidate pattern being less than or equal to a period threshold.
