A program evaluation system and method

Abstract

The invention provides a program evaluation system and a program evaluation method. The program evaluation system comprises an input unit, a program index attribute space construction unit, a weighted index space construction unit, a program evaluation model construction unit, an optimal solution determination unit and an obtainment unit; the input unit is used for inputting weighting methods, programs to be evaluated and evaluation indexes; the program index attribute space construction unit obtains a decision making matrix according to the programs to be evaluated and an evaluation index calculation formula; the weighted index space construction unit calculates the weight of the evaluation index of each program according to the weighting methods and multiplies the weight by a linear expression coefficient of each weighting method, so that a compound weight vector is obtained; the program evaluation model construction unit utilizes the decision making matrix and the compound weight vectors to construct target optimization models according to the evaluation method; the optimal solution determination unit adopts the Lagrangian multiplier method to solve optimal solutions of the program evaluation models; the obtainment unit obtains an optimal linear expression coefficient vector and an optimal compound weight vector of each evaluation index of each program according to the audience information and optimal solutions of the programs to be evaluated, and thereby a comprehensive evaluation value of each program is obtained. The invention reflects objective and subjective decision making at the same time, realizes the scientific weighting of evaluation indexes, and increases the accuracy of evaluation.

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. 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 weights must be scientific and objective, which...

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 unreasonable.
