2.6 MINING OF COMPACT RULES
As the size of the database increases, it gets more difficult to analyze larger
amounts of data by finding all possible semantic relationships among them.
Hence, the rule-mining focus can be on deriving rules with full confidence.
As described in the previous sections, these rules are derived based on the
dependencies between a target attribute and other condition attributes. A
problem with this plain rule-mining approach arises when many rules are
derived or many condition attributes are involved in the antecedent of each
rule. Hence, for the efficient use of the rules, it is important to be able to
derive rules that are compact.
In this section, a new concept, called a Semantic ...
