Measuring User Satisfaction of Networked Software Based on User Behavior

End user satisfaction of software or information system is an important research topic. However, existing research has been focused on questionnaire and indicators selection. An important issue has not been paid enough attention so far is that the traditional method is hardly suitable in web 2.0, which user using pattern and software runtime environment have changed. In this paper, we present a new approach to evaluate user satisfaction based on user behavior. We give the measure indicators and their calculate method. Based on a case study and a simulate experiment, we showed the feasibility and maneuverability of this approach.
