Abstract:The increasing or decreasing technology of the saturated information dimension was applied to decompose and analyze the structure of information acquisition subspace one, and the acquisition of the value of saturated information dimension was divided into two parts—White and Grey. The saturation information dimension was used as the correlative order, applied to describe the grey correlative space, and the correlative oder was used to describe the correlative degree between information, thus obtaining a new mathematical model focusing on information resource.
