Abstract
The invention relates to the internet field, and especially relates to an electronic commerce client evaluation judging and marking system. The system comprises a client, a network connection device, an ID similarity judgment module, a content similarity judgment module and a false evaluation marking module. The client acquires relevant evaluation data information of a target commodity through the network connection device, and outputs the information to the ID similarity judgment module, the content similarity judgment module and the false evaluation marking module which are sequentially connected. Based on an ID similarity analysis of target commodity evaluations, the system determines whether evaluation content given by the same or similar evaluation IDs are the same or similar through the content similarity judgment module; if the evaluation content is the same or similar, the system determines that the IDs giving the same or similar evaluations are the false evaluation IDs; and the system timely marks the false evaluation IDs and the corresponding evaluations through the false evaluation marking module. The system can automatically indentify the false evaluations from the target commodity evaluations.
