presented an ontology-based association rule mining
method, which query the ontology to filter the instances used
in the association rule mining process Ontology in this work
provides the constraints for queries in the association mining
process. The search space of association mining is constrained
by the query returned from the ontology that some items
from the output association rules are excluded or to be used
to characterize interesting items according to an abstraction
level. The user constraints include both pruning constraints,
which are used for filtering a set of non-interesting items, and
abstraction constraints, which permit a generalization of an
item to a concept of the ontology.
