Active Data Mining

We introduce an active data mining paradigm that combines the recent work in data mining with the rich literature on active database systems. In this paradigm, data is continuously mined at a desired frequency. As rules are discovered, they are added to a rulebase, and if they already exist, the history of the statistical parameters associated with the rules is updated. When the history starts exhibiting certain trends, speci ed as shape queries in the user-speci ed triggers, the triggers are red and appropriate actions are initiated. To be able to specify shape queries, wedescribe the constructs for de ning shapes, and discuss how the shape predicates are used in a query construct to retrieve rules whose histories exhibit the desired trends. We describe how this query capability is integrated into a trigger system to realize an active mining system. The system presented here has been validated using two sets of customer data.
