The invention discloses a training method of a multimedia content evaluation model, and the evaluation model comprises an evaluation network module and a post-processing unit; the evaluation network module comprises a classification network sub-module and a subsequent dimension reduction sub-module, and the training method comprises the following steps: training the evaluation network module; inputting the plurality of picture data into the trained evaluation network module to obtain evaluation network module output, and inputting the evaluation network module output into a post-processing unit for processing to determine post-processing parameters for converting the evaluation network module output into a final evaluation value. The invention also provides a multimedia content evaluationmethod and evaluation device, and electronic equipment. According to the scheme, the training data acquisition difficulty can be effectively reduced, learning of multimedia content features is betterdriven, and therefore the
