The importance of user satisfaction is increasing in the competitive market. However, with the development of the Internet, user satisfaction models that based on time-consuming survey become unsuitable for software products, which evolve faster than ever. To support software evolution, this paper presents a new user satisfaction evaluation approach by analyzing user comments, the results of which are instructive for the next-step of evolution. We give an evaluation framework and calculate methods for user satisfaction analysis. Based on a case, we show the feasibility and maneuverability of this approach.
