Application-Adaptive Model Evaluation in E-government Spatial Information Service

Spatial information service plays an important role in E-Government, but different models differ most in various applications of decision-making support activities. Therefore, how to evaluate the applicability of spatial application model is the key problem for the usage of spatial models in E-Government application. In this paper an evaluating model has been proposed to solve this problem. Based on semantic analysis, the author explicates the model for the evaluation of model applicability, which is constructed by spatial application model¿s commonness and specialty and is layered and dynamic-extended. The author also provides its software prototype. At last, this method and software tool are successfully used in a test of E-Government spatial information service applicability evaluation.
