Performance Evaluation of E-Government Information Service System Based on Balanced Scorecard and Rough Set

With increased E-government website, it becomes more and more important how to evaluate objectively and accurately performance of e-government information services. This paper builds evaluation index system based on balanced scorecard. Then rough set theory and information entropy are adopted to process the obtained research data. Firstly, property reduction is processed to identify redundant indexes, sencondly, the weights of each index are calculated. Finally, we get the evaluation index system of the e-government services made up of four dimensions and fourteen index, and also assign the weight of each indicator. The application of this system will help the government administration to find the defects of current e-government information services, and will provide support for the system´s improvement.
