1. An automatic classifying system in a dining environment, comprising: a server for directly or indirectly receiving a set of pictures, the server including a picture analysis module to classify a picture, from the set of pictures, according to at least two classifications and generate an analysis result, wherein the set of pictures are received via Internet from an electronic device, wherein the server transmits the analysis result to a web-platform system for initiating display of the picture and the analysis result, wherein the picture analysis module analyzes the picture according to the at least two classifications for obtaining at least two classification weights corresponding to the at least two classifications, respectively, and selects a higher classification weight, of the at least two classification weights, and a classification associated with the higher classification weight as the analysis result for the picture, wherein the server further includes a classification check module for determining whether previous and next pictures, from the set of pictures, are of a same classification, and wherein the classification check module compares the higher classification weight corresponding to the picture with a weight approximation corresponding to a classification of the previous and next pictures when the previous and next pictures are associated with the same classification, and re-assigns the picture to the classification of the previous and next pictures when the higher classification weight is smaller than the weight approximation.
