METHOD FOR MINING IMPORTANT PATTERN OF HIGH RANK K, DEVICE FOR PERFORMING SAME, AND RECORDING MEDIUM STORING SAME

摘要

A method for mining an important pattern of a high rank K comprises: (a) a step of generating a user header table including a generation time, user characteristic information, and a user data link; (b) a step of receiving user data represented by a combination of at least one item from the user header table, performing a data tree visit based on each of the at least one item, and updating a data tree path; and (c) a step of additionally associating the user data as a tail node to a tree end node on the data tree path and sequentially connecting a tail node related to a corresponding user with a corresponding user data link as a start link. Therefore, the method for mining an important pattern of a high rank K can provide average characteristic information for a data group or a transaction to which a corresponding pattern belongs by mining a K number of high-rank important patterns corresponding to a specific time range for the generation time of the user data.;COPYRIGHT KIPO 2017
