Abstract

The embodiment of the invention provides a video playing evaluation method and device. The method comprises the steps of obtaining a grade value of a definition grade factor of a played video and a numerical value of a target playing factor; Determining a target evaluation function corresponding to the obtained grade value from the corresponding relationship between each grade value and the evaluation function; And obtaining an evaluation result of the played video based on the target evaluation function and the numerical value of the target playing factor. According to the technical scheme, the definition grade factor is added in the evaluation process to serve as the non-service-quality feature, the service quality feature of the playing interaction factor and / or the playing experience factor is further included, and evaluation is more comprehensive compared with evaluation in the prior art based on the non-service-quality feature and the service quality feature. Wherein the definition level factor is related to the playing interaction factor and the playing experience factor, and the playing interaction factor is not related to the playing experience factor, so that the increasing number of the cross features is controlled, and the increasing degree of the evaluation complexity is further controlled.
