Abstract: With the of theory of fuzzy set, combined with concept and method of fuzzy query, rules template, linguist quantifier, and so on, the rules are further constrained in quantitative information so as to solve the limitative problem, i.e., not thinking over quantitative information with correlation of the items, on the basis of which the mining of association rules based on fuzzy quantitative constraints are put forward. By experiment, the mining method put forward in the paper exhibits nicer flexibility, and more pertinence in its mining effect.

Key words: data mining, association rules, fuzzy query, quanti tative constraints
