Abstract—In order to accurately predict the Web service Qos in a highly dynamic environment,we put forward a Qos dynamic prediction method based on Semi-Markov Processes(SMP) and Case-based Reasoning(CBR).This method firstly uses semi-Markov process to predict business state of web service in the future, and then applies the technology of CBR to predict Web service QoS, for example,when the service deals with a specific task. Experimental results show that this prediction method can improve the accuracy of Web service QoS greatly. The results provides a reliable basis for the objective evaluation and successful Web service composition.
Index Terms—Web Service; QoS(Quality of Service); Dynamic Prediction; Semi-Markov Processes; Case-based Reasoning.
