A device for assessing quality of a multimedia resource, comprising:

• memory for maintaining a log storing information about user behavior associated with a plurality of multimedia resources provided to terminal devices, the information about user behavior including information that indicates percentages associated with different instances of user behavior on each multimedia resource, and the information stored in the log including indicator data for describing user behavior on the multimedia resource;
• a first determining unit configured to determine a cumulative distribution vector of the multimedia resource according to the indicator data;
• a second determining unit connected to the first determining unit and configured to determine an upper boundary vector and a lower boundary vector of the multimedia resource according to the cumulative distribution vector;
• a third determining unit connected to the first and second determining units and configured to determine a quality score of the multimedia resource according to the cumulative distribution vector, the upper boundary vector, and the lower boundary vector;
• and
• a communication interface for outputting dynamic ranking of the plurality of multimedia resources provided to the terminal devices based at least in part on the quality assessment of the multimedia resource among the plurality of multimedia resources based on the determined quality score.
