| Abstract: | It is difficult to select proper comprehensive evaluation models.In order to solve this problem,key attributes and typical comprehensive evaluation models have been selected which play an important part in model selection.Then a model selection method has been proposed which constructs the decision tree based on C4.5 by calculating the entropy of the selected key attributes.Finally the effectiveness of this method has been confirmed by empirical study on city and municipal economy comprehensive evaluation issues which provide the support for decision making. |
