RESEARCH ON ALL NEGATIVE ASSOCIATION RULES MINING IN A DATABASE
摘要
Abstract
In a database, associated rule information is one of the representation formats for knowledge. Negative association rule mining is so important to study in database association information mining that it bears wide application value. Existing mining approaches can not obtain all negative rules from a database. The paper considers to extract all negative association rules from a database through: (1) scanning the database to build a database frequent pattern tree called DFP-tree; (2) acquiring based on pruning the DFP-tree all small infrequent itemsets; (3) acquiring via upward closure packets of large frequent itemsets in ASI all infrequent itemsets; (4) based on the previous 3 steps adopting correlation metric as one of rule interest measurements to extract negative association rules. Theories and experiments validate the correctness and efficiency of the presented algorithm.关键词
