Patent ID: 8341006

Claim:
A system for product recommendation, comprising: a plurality of automatic service equipments, wherein each of the automatic service equipments is linked to other automatic service equipments via a communication network, each of the automatic service equipments comprising: a storage device in which data of a plurality of first user groups, data of a plurality of first product groups, a relation matrix and a reliance list are stored, wherein the relation matrix is used to record correlation coefficients between the first user groups and the first product groups, and the reliance list comprises network connection data of the other automatic service equipments; an input device used for receiving input data; and a processing device electrically connected to the storage device and the input device, the processing device comprising modules that when executed by the processing device cause the processing device to: obtain, via a data obtaining module, data of other first user groups, data of other first product groups and other relation matrixes from the other automatic service equipments via the communication network in accordance with the network connection data of the other automatic service equipments recorded in the reliance list; integrate, via a group integrating module, the data of the other first user groups into the data of the first user groups, and integrating the data of the other first product groups into the data of the first product groups; revise, via a matrix-revising module, the relation matrix in accordance with the data of the integrated first user groups, the data of the integrated first product groups, the other relation matrixes and the relation matrix, thereby enabling the revised relation matrix to record the correlation coefficients between the integrated first user groups and the integrated first product groups; and provide, via a recommendation module, data of at least one recommended product in accordance with the input data, the data of the integrated first user groups, the data of the integrated first product groups, and the revised relation matrix.
