Abstract: The key to set pair analysis method is to compute the connection degree.The structure of set pair correlation function provides a new soft computing method of describing the relationship between the collections and determining the connection degree express formula.Firstly,based on rough set,the attribute correlation function was defined and the basic properties were discussed.Secondly,the set pair correlation function was defined and it was proved that the set pair correlation degrades into the attribute correlation function when any collection of set pair is expended to the whole region.The basic properties of the set pair correlation function were discussed.What’s more,the synthetic operations and operation laws were given.Finally,the feasibility and practicability of the set pair of soft computing method about attributes were illustrated through a case study.

Key words: Rough set,Connection degree,Attribute correlation function,Set pair correlation function
