文摘The plausibility relation which is generalization of fuzzy relation and probabilistic relation is proposed in thepaper. We think data mining to be a process of finding the plausibility relation in database and correlativity measure tobe a particular plausibility relation based on correlativity sets. The critical calculates such as the accuracy of the roughsets, the confidence and the bayesian form in data mining can be united using the correlativity measure. The GPDM(General Process of Data Mining)that represents the nature of data mining is also proposed. The data mining theoreti-cal foundation and frameworks based on correlativity sets are also given and discussed in the paper.
