Abstract: Study the core “data results of value” of big data.Firstly,the rough set method,cluster-based method,quotient space method,fuzzy information method and cloud model method for granulating big data are described.According to their common characteristics —“division”,the big data is “granulated”,and a “granularity tree” is established in the big data according to the size of division.“granular space” is defined in the “granular Tree”.Then it defines the usage relationship between the granular space and the representative project,and the conditions that the usage relationship of different granular spaces meets.Finally,according to the usage of each particle and each particle set in the usage relationship of the particle space,the usage is divided into three types:“regular use” “inevitable use”and “related use”.Take the average value of their attributes and objects and round them to 0~100,as the values of “data results of value”“inevitable value” and “relevant value” of big data.The effective calculation method of the core “data results of value” of big data is given,and the application examples of the core “data results of value” calculation of big data in telemedicine,urban management,universities and other fields are also given.

Key words: Big data value, Data results of value, Granularity tree, Usage relationship, Regular use, Inevitable use, Related use
