Problems solved by technology

The objective weighting method has objective standards for weighting, and can use a certain mathematical model to calculate the weight coefficient of the attribute. Its disadvantage is that it ignores the subjective preference information such as the subjective knowledge and experience of the decision maker, and sometimes the weight coefficient is not correct. reasonable phenomenon

Abstract

The invention provides a program evaluation system and method based on a variable coefficient method. The system comprises an input unit, a variable coefficient matrix construction unit, a variable coefficient weight acquisition unit and an acquisition unit, wherein the input unit is used for inputting a program to be evaluated and an evaluation index; the variable coefficient matrix construction unit constructs a variable coefficient matrix according to the mean value and the standard deviation of the evaluation index; the variable coefficient weight acquisition unit calculates the weight of each index for the system; and the acquisition unit obtains the comprehensive evaluation value of each program and program sorting according to the audience rating information of the program to be evaluated and the weight of each index. By use of the program evaluation system, the original data information of the program to be evaluated can be fully reflected, the scientific empowerment of the evaluation index is realized, and program evaluation accuracy is improved.

Description

technical field [0001] The present invention relates to the field of radio and television, and more specifically, to a program evaluation system and method based on the coefficient of variation method. Background technique [0002] In the field of broadcasting and television, multiple indicators are usually used to evaluate users' preferences for programs, and the assignment of evaluation index weights is an important part of multi-objective decision-making. The weight of the index is the reflection of the different importance of the index in the evaluation process, and it is a comprehensive measure of the subjective evaluation and objective reflection of the relative importance of the index in the decision (or evaluation) problem. Whether the weight assignment is reasonable or not plays a vital role in the scientific rationality of the evaluation results; if the weight of a certain factor changes, it will affect the entire evaluation result. Therefore, the assignment of we...
