E-COMWEB: a quality Model for e-commerce Web sites

This paper introduces a statistical approach to the construction of a new Quality Model for Web Sites (E-COMWEB). A brief overview on Web Sites Quality Models and used top-down and bottom- up approaches are introduced. The approach to the construction of E-COMWEB is different from most of the current ones: exploiting the considerable number of available Web Sites, it uses statistical analysis for validating the relations between variables in a traditional Quality Model and finding new ones. The process for constructing such a newly conceived model and its composition are presented and discussed, and examples of its application are shown.
