ZHU Heng-min,LIU Jian-guo,WANG Ning-sheng (Research Center of CIMS Engineering,Nanjing University of Aeronautics and Astronautics,Nanjing 210016,China.)  
To the meta rule instantiation of meta-rule-guided data mining,the current methods to instantiate meta rule are discussed.It is pointed out that,besides data type of attribute,the set of attribute value restricts the instantiation of the same attribute variable of meta rule.The notion of connected attributes between relation tables and relative theories are proposed,based on which a method of instan meta rule is given.An example shows that the proposed method is effective and can greatly reduce the size of meta rule candidate instantiation set.
