Accurate predicting the Web Service computation times is an important issue for scheduling successfully in Cloud Computing Environment. The authors propose a novel rough set algorithm to predict that employee rough set theory to acquire a reduced attribute collection and then calculate the computation prediction. The novel algorithm is based on rough set theory and can determine a reduced attribute collection. The reduced attribute collection is some factors which can determine the runtime of a web service. They conduct experiments to verify the effectiveness of their hypothesis. The experiments result shows that their hypothesis can be a general solution for predicting the computation times of a web service in cloud computing environment.
