|Title:||ITEM SET DETERMINATION METHOD, APPARATUS, PROCESSING DEVICE, AND STORAGE MEDIUM|
Provided are an item set determination method, an apparatus, and processing device. The method comprises: determining at least one target transaction corresponding to a to-be-processed item set; determining a time validity value of the to-be-processed item set in an uncertain database; determining an expected support degree of the to-be-processed item set; multiplying the expected support degree of the to-be-processed item set by an item set weight of the to-be-processed item set, and determining an expected weight support degree of the to-be-processed item set; and if the time validity value of the to-be-processed item set in the uncertain database is not less than a predefined minimum time validity threshold, and the expected weight support of the to-be-processed item set is not less than the product of the predefined minimum expected weight threshold and the total number of transactions in the uncertain database, then it is determined that the to-be-processed item set is a high expected weight item set of a valid time (S240). The method realizes the determination of the high expected weight item set of the valid time in the uncertain database.
