Modifying fuzzy association rules with linguistic hedges

We introduce linguistic hedges in data mining, especially in association rule mining, based on our recent work on fuzzy taxonomic structures where fuzzy rules like “expensive cosmetics ⇒ tropical fruits” can be dealt with. In order to express the decision knowledge more naturally, the notion of fuzzy association rules with linguistic hedges is presented such as “very expensive goods ⇒ sort of fruit”. Furthermore, a method of mining all possible fuzzy association rules with a particular pool of linguistic hedges is discussed
