Association rule visualization

Definition

Association rule mining finds frequent associations between sets of data items from a large number of transactions. In market basket analysis, a typical association rule reads: 80% of transactions that buy diapers and milk also buy beer. The rule is supported by 10% of all transactions. In this example, the 10% and 80% are called support and confidence, respectively. Depending on the user-specified minimum support and minimum confidence, association rule mining often produces too many rules for humans to read over. The answer to this problem is to select the most interesting rules. As interestingness is a subjective measure, selecting the most interesting rules is inherently human being’s work. It is expected that information visualization may play an important role in managing a large number of association rules, and in identifying the most interesting ones.

Historical Background

An association rule reflects a many-to-many...
