Claim:
A method for managing merchandise information, the method comprising: acquiring merchandise information of a plurality of merchandises, and storing the merchandise information into a storage system of an electronic device; setting a plurality of categories and multi-level sub-categories, and classifying the plurality of merchandises into corresponding categories and sub-categories, wherein each of the categories and sub-categories is assigned a level, and each level is assigned to a serial number; calculating a relative coefficient between a selected merchandise and each of the other merchandises in the same category as the selected merchandise according to a price coefficient, a category coefficient and a formula of F(x)=(N/M)*R1+(1-O/P)*R2, wherein: F(x) represents the relative coefficient of two merchandises in the same category; N represents a serial number of a level of the same sub-category if the two merchandises both belong to the same sub-category, or represents a serial number of a level of the category if the two merchandises do not belong to the same sub-category; M represents a total number of levels that the category has R1 represents a proportion between the category coefficient and the relative coefficient; O represents a price difference between the two merchandises; P represents a sum of prices of the two merchandises; and R2 represents a proportion between the price coefficient and the relative coefficient; predefining a threshold value to compare with calculated relative coefficients; determining one or more relative coefficients that are larger than the threshold value, and selecting related merchandises corresponding to the determined relative coefficients; linking the related merchandises to the selected merchandise; and displaying the merchandise information and the linked merchandises of the selected merchandise on a display of the electronic device.
