Abstract: ［Purpose/Significance］Government hotlines are important channels for public service and participation. With the analysis of the accumulated amount of data, requirements of the public and enterprise could be revealed and issues of urban governance could be solved. Evaluating the management and application of government hotline data is helpful to give full play to its value.
