A user satisfaction analysis approach for software evolution

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.
