E-business website evaluating base on extension theory

Website evaluation is affected by multiple factors, that is important for E-business system evaluation. The principles of extension theory have been used in this paper to establish the matter-element model for the evaluation of website. The quantitative evaluated results have been given through the calculation of the matter-element dependent degree. A case analysis has indicated that by using extension theory, the evaluation index of the multiple factors on website evaluating is effective and feasible. The conclusions obtained are basically consistent with the engineering practice and have the significance of reference for solving similar problems in website evaluation.
