Extending attribute-oriented induction as a key preserving data mining method

摘要

Attribute-Oriented Induction (AOI) is a set-oriented dat amining technique used to discover descriptive patterns in large databases.The classical AOI method drops attributes that possess a large number of distinct values or have either no concept hierarchies,which includes keys to relational tables.This implies that the final rule(s) produced have o direct link to the tuples that form them.Therefore the discovered knowledge cannot be used to efficiently query specific dat apertaining to this knowledge in a different relation to the learning relation.
