Comprehensive evaluation model of smart city economic management efficiency based on multidimensional data mining

In order to improve the comprehensive evaluation quality of the economic management efficiency of smart city, multidimensional data mining technology is applied to the comprehensive evaluation modeling of the economic management efficiency of smart city. In order to avoid the maximum distance between classes caused by the large sample problem, MMC algorithm is used to mine multi-dimensional data from multiple dimensions, including the status, rationality and management mode of smart city economic management. Based on the multi-dimensional data of smart city economy, it is necessary to build an evaluation index system. The weight of each evaluation index is calculated, and in order to eliminate the influence of dimension, the index is quantized. Combined with entropy and coefficient of variation, the calculation model of comprehensive evaluation index of smart city economic management efficiency is calculated. The experimental results show that, compared with the traditional evaluation methods, the text method can ensure the evaluation efficiency and improve the evaluation accuracy.
