ABSTRACT:
A method including providing a database with a plurality of items, each item having several attributes, and developing and displaying a cluster map (SOM) attribute plane from the items and attributes, including clusters of items having similar attributes. Selecting an attribute of interest and splitting the plurality of items into clusters of interest based on distribution of the selected attribute. Utilizing rule induction to provide a rule for each cluster of interest, drawing a line around adjacent items in the SOM attribute plane for each rule to form at least one complete fenced area in the display, and comparing fenced areas to clusters to separate statistically meaningful rules from statistically meaningless rules or coincidences.
